Introduction

Ultrasonic cleaners are a great way to clean a wide variety of household and industrial items without using potentially harmful chemicals or abrasive materials. The cleaner consists of a container that the items are placed into, they are then subjected to high frequency sound waves which create cavitation bubbles in ordinary tap water. The bubbles bombard the item to be cleaned at high speed and knock the tiny particles of dirt and grime off of it.

A separate and totally distinct use for the ultrasonic cleaner is in the making of liposomal Vitamin C. This is beneficial in helping your body’s cells absorb more and for less to be passed as waste.

The following is our selection of the best ultrasonic cleaners on the market at the moment:

Safely and hygienically clean all your bracelets, necklaces and rings as well as eye glasses, dentures, coins, CDs and DVDs and a host of other things. Your items will have their sparkle restored in a matter of minutes.

You should always bear in mind when thinking of using an ultrasonic cleaner of any kind that the more sensitive and brittle the object you are cleaning, the more chance there is of some slight damage like flaking occurring in the cleaning process. Even though it uses water, the cleaning process bombards the object at high speed using sound waves to create microscopic cleaning bubbles and although the cleaning process is relatively gentle it could potentially cause some damage to an extremely brittle object.

The capacity of the cleaning basin is 20.3 ounces (600ml) which equates to 6.1″ x 5.1″ x 1.7″), a good size that will hold any small household item but if you need a slightly bigger basket for some specialist application see the number one selection below.

The item comes with a full one-year manufacturer’s warranty from Famili, which is better than some of the rival ultrasonic jewelry cleaners on the market but it would be a surprise if you ever needed to use it, such is the reputation for reliability that the FM800WW has.

If you want great performance at what is a bargain price, then this would be the selection for you. Remarkable value for money and remember it is fully backed by the manufacturer.

corentium-home-radon-detector-by-airthings-223

Radon gas is known as the silent killer and the Corentium Radon Gas Detector will help to protect you, your family and your workplace from its dangers. Radon is a radioactive gas that is given off naturally from rock and gets into houses at the lowest points – for example foundations, water pipes, cracks in walls at low level and cavity wall insulation. One of the problems of modern very highly energy-efficient houses is the lack of ventilation, this can lead to a build-up of radon as the gas lies at low level and once it is in the house does not have a means of escape. Good radon gas testing kit is essential to detect dangerous levels of the gas and allow you to keep your family safe. This instrument is the most advanced electronic radon gas detector available as a handheld unit at an affordable price. Don’t take a chance with potentially dangerously high levels of radon in your home, in your school or in your workplace when the Corentium lets you monitor average radon levels over 1 day, 7 days and a year – all at the same time. This is a very accurate machine with only a 5% error band and is extremely energy efficient – it will run for up to 3 years on one set of batteries. Recalibration isn’t a problem either as it is not required for the whole lifetime of the meter. Another big plus point is the simplicity of use, you literally don’t need to do anything other than insert the batteries and press the reset button for the monitor to display all the information you need. Other radon testing equipment is single use but with this kit you can reset it and reuse, saving a lot of money against the cost of expensive professional radon testing services.

 

Introduction

The purpose of stereo microscopes in general is to enhance resolution, this can apply to an object or image under the scope. A stereo microscope (also known as a dissecting microscope) uses two separate optical paths to give different viewing angles to the left and right eye, resulting in a 3D image of the sample. This type of image is essential for a wide range of industries including watch-making, electronic circuit boards, dissection and microsurgery, the medical industry. Stereo microscopes are also widely used in engineering, biology, forensics, and scientific labs
Other types of microscope available are digital, which use a monitor to display the image rather than looking through a lens and the compound microscope, which use a “compound” optical system consisting of an eyepiece and objective lens.

#3 – Fixed Gas Detector, C3H8, CH4

safe-t-alert-fixed-gas-detector

Next we have selected the Safe T Alert fixed propane gas and natural gas detector, a must-have appliance if you cook or heat your home using propane gas or natural gas. Both Propane gas and natural gas can result in fires or explosions if they leak and are exposed to a source of ignition. The 40-411-P can be mounted in most locations and is fixed near the floor – where heavier propane gas will gather in the event of a leak – using either screws or velcro. An alarm should be fitted near to every appliance that uses gas, also consideration should be given if you live near a waste disposal area or pit as these produce natural gas which can find their way into your house. The unit comes with a decent length of electrical cord and plugs right into a 120V AC mains supply outlet.

 

#2 – Bacharach Leakator Jr 0019-7075 ABS Plastic Combustible Gas Leak Detector

leakator-jr-combustible-gasleak-detector

Runner-up in this section is the Bacharach Leakator Jr, a combustible gas leak detector. This tool is brilliant if you are working in the plumbing industry or other related jobs like HVAC installation or maintenance but is also perfect for the gas industry – inspecting valves, meters and regulators and surveying pipelines, as well as the general building trade and construction industries. The detector easily pinpoints even small gas leaks without any calibration being required so it is very low maintenance. The unit itself is only 6 inches long and has a flexible probe which extends a further 12 inches. It has a loud warning sound on gas detection and two levels of sensitivity, for finding the approximate area then spotting the exact location of the leak. Not only can this product protect you from a costly insurance claim, it can save the lives of you and your customers.

#1 Y201 Propane and Natural Gas Leak Detector; Portable Gas Sniffer to Locate Gas Leaks of Combustible Gases

yeezou-y201-propane-and-natural-gas-leak-detector

Our top pick in the Gas Detectors category is the Yeezou Y201 which is an essential piece of kit for locating any kind of dangerous explosive gas. Some of the gases that the Y201 can locate include propane, butane, kerosene gasoline, ethane, coal gas and sewer gas. This is a serious piece of kit that can save lives as well as save money by finding the source of leaks so that they can be fixed.

It can cost into the hundreds of dollars to call out a technician to find your leak, save yourself the money –  use this kit just once and it will more than pay for itself. Easy to use by just running the sniffer along pipework, tanks or your car to detect the leak. You cas also lose hundreds of dollars worth of gas if you have a leak, not to mention that it could be lethal for you and your family. Th Y201 sniffer will find the gas, save you money and potentially save your life.

Another point that you should consider is that gas does not always have an odour so you could have a leak without knowing it. If your gas bill has risen unexpectedly without you using more gas you may have a leak and you should get it checked. It will be cheaper for you to buy one of these detectors and check it out yourself than pay for somebody else to do it. You can also check out your friends, family and neighbors properties while you’re at it!

The Y201 detector is extremely light and portable and can be taken anywhere both indoors or outdoors to detect leaks. The sniffer is highly flexible as it has a 12 inch head that can be bent into any confined space; hole, pipe tank or under floorboards, anywhere that gas can be found to have leaked. Sensitivity of the sniffer can be varied to filter out false alarms from very small quantities of gas that could trigger a false alarm. Conversely the sensitivity can be increased to detect small quantities of leakes gases.

The alarm is both audio (variable tone alarm, maximum volume of 85dB) and visual with 6 LEDs. On detection of flammable gas an alarm sounds and the LED display indicates gas is present.

Also detects relative concentrations of the following combustible gases: methane, LPG, LNG and toluene as well as other flammable explosive gases.

Introduction

Vacuum chambers are devices for removing gases including air from an enclosed space. The air is sucked out of the enclosure using high performance vacuum pump and the chamber has to be sealed to a high degree to prevent ingress of air using silicon gaskets which do not degrade and are resistant to chemicals. The chambers are used in industrial as well as scientific applications and are capable of maintaining their vacuum seal for days at a time.

Here are the best 5 vacuum pumps and heaters on Amazon, starting with number 5…

#5 BACOENG 5 Gallon Tempered Glass Lid Stainless Steel Vacuum Chamber 

bacoeng-5-gallon-tempered-glass-lid-stainless-steel-vacuum-chamber

The BACOENG 5 Gallon Tempered Glass Lid Stainless Steel Vacuum Chamber is ideal for use in stabilizing wood and degassing silicones, resins, epoxies and essential oils. The chamber provides exceptional stability and will hold its pressure at a steady 30″hg (inches of mercury – approximately 14.5 psi) for as long as you need it.

The BACOENG is well designed and engineered to make it as easy as possible for the user. The chamber is made from quality stainless steel with a chromium layer to prevent any oxygen whatsoever getting in that could damage the chamber or your contents. Stainless steel is the perfect material due to its high resistance to temperature and corrosion and the BACOENG brand ensures that the chamber is built to the highest possible industry standards.

The lid is made from tempered glass which has much stronger resistance against cracking than the standard acrylic lids on other chambers. It also allows for visibility of the contents of the chamber at all times and allows work with more volatile compounds that could damage an acrylic lid. Other design features include the inlet valve being mounted on the side rather than the top, beneficial when releasing pressure and also when introducing material into the chamber, preventing direct spraying onto the contents and an observation window on the side. Th.e design of the chamber has been verified in labs and is proven to be reliable and safe

High quality accessories supplied with the BACOENG 5 Gallon Stainless Steel Vacuum Chamber:
Glass lid, 3-Way valve (with particle filter), oil filled pressure gauge, 5ft vacuum hose, reversable rubber gasket (can be flipped if damaged), non-stick silicone mat (food-grade)

Negative points to consider
As with any product there are always some slight downsides and for full disclosure here’s what we have found that you might want to consider:
– The inlet being on the side instead of the top slightly limits the depth of liquids that you can fill to
– The unit needs very minor assembly that can be done in 5 minutes using an adjustable wrench
– Reports that some of the minor hardware accessories are not of the same very high quality as the chamber itself, although this in no way detracts from the operation or reliability of the unit

The BACOENG has high ratings for Sturdiness, Value for money and Ease of use
This product has 94% positive customer feedback rating on Amazon and is the number one best-selling item in the Lab Vacuum category

Negative points to consider:
There are very few minor negatives but people have reported that the scale on the gauge can be difficult to read at certain pressures. This in no way detracts from the quality or accuracy of the actual gauge itself.
The other main bugbear for some is that the kit does not come with an R134A adaptor for a 12oz can and this has to be bought separately, a very minor expense if you need one at around $6.99.

Introduction

There is a great range of electronic kitchen scales available nowadays. The design is modern and sleek and ergonomic in cool technical colors like silver and black. Accuracy has improved enormously over the years and in general modern day kitchen scales are very precise and the measurements can be relied upon. Although the scales are only intended for use in the kitchen, the design models are calibrated in a science lab to ensure that they are as accurate as possible.

The following are some recommendations of what we consider to be the best electronic kitchen scales on the market at the moment…

#5 Ozeri Pro Digital Multifunction Kitchen and Food Scale, Silver Finish

ozeri-pro-digital-multifunction-kitchen-and-food-scale

These are traditional round shaped kitchen scales and look great in a range of exciting colors to match any kitchen decor. They look both taditional and modern at the same time and will look perfect in any kitchen.

The main things that distinguish the Ozeri Pro kitchen scales is its accuracy for weights up to 12 lbs, the immediate response time and the simplicity of use. The scales have a degree of precision that you don’t find in many similarly priced models with 0.05 ounce graduations – equivalent to just one gram. The Pro has been favorably compared to much more expensive models by users who say the accuracy is spot-on.

Elegant and easy to use, with all the operations able to be carried out via two large buttons that give off a satisfying click to let you know they have been pressed correctly.

A must-have for all kitchen scales nowadays is the tare net weight feature, this feature calculates the weight of the ingredients without including the weight of the measuring bowl so you can be confident your recipes will be accurate and your dishes will turn out spot on. The other button instantly convert your units from ounces to grams or kilograms to pounds and vice versa with the large display screen showing the results. The Pronto runs off batteries which are supplied and last for ages, it uses very little power and you will get a long time of use out of your batteries.

The item ships internationally so if you’re outside the USA you can still get it sent to you with Amazon’s legendary speedy delivery.

 

#4 Kinzi Digital Touch Kitchen Scale (12 lbs Edition), Tempered Glass in Clean White

ozeri-pro-digital-multifunction-kitchen-and-food-scale-2

With a 12 lbs measuring ability, the Kinzi has a bit more measuring capacity than most of the other scales in the same price range so if you need that little bit extra for what you’re weighing this would be the choice for you. Built with typical German efficiency, the high precision sensors ensure that these scales are highly accurate in increments of 1 gram (0.05 oz).

Like the others in this section the Kinzi has a zero tare function to allow automatic subtracting of the eight of the bowl, this speeds up the cooking process as you can just reset the reading and add the weight of the next ingredient rather than having to stop and fiddle around with calculations. The large bright display is stable and the reading stays on for 2-3 minutes, some rival scales will switch off a lot quicker than that causing frustration if you need to start over again. Another great thing about these scales is that they are so easy to clean, there are no unnecessary grooves or tricky corners to get into, everything is on the same surface so cleaning is a breeze.

Featuring a superior build quality than most of the competition with tempered glass surfaces rather than the plastic finish available elsewhere, this unit looks and feels good quality. As a measure of the confidence of the manufacturer, they guarantee to respond to any questions about your purchase within 24 hours, giving you tremendous peace of mind. As another small bonus, the instruction manual is clear and well written in good English, how often have you picked up instructions and not been able to fathom them out!

 

#3 Etekcity 11lb 5kg Digital Multifunction Food Kitchen Scale with Removable Bowl 2.15L Liquid Volume Room Temperature and Timer, Backlight LCD Display

etekcity-11lb-5kg-digital-multifunction-food-kitchen-scale-with-removable-bowl

Our number three selection is this great set of scales from Etekcity and they come highly recommended. Measuring power is delivered by means of the built-in high precision strain gauge sensors which provide tremendous accuracy even at very low quantities and the display is clarity itself, backlit in bright blue.

An unusual thing about this set of scales is that in addition to the obvious function of weighing, the scales also have an alarm timer and temperature sensor! A bit quirky maybe but if you are getting this extra functionality at the same price as other scales that don’t have it – why not? At least Etekcity have gone out of their way to try and distinguish their product from the masses.

Sleek and clean looking lines are the order of the day here with an expensive looking stainless steel finish that will outlast most things in your kitchen and it even comes with its own mixing bowl, again quite unusual for a product in this price range. There are warning lights for low battery power and overload.

You will never need measuring cups and spoons again, these scales replace them, with the tare reset feature which allows you to measure as you’re going along – in any units. You just put your bowl on the scale and add your first ingredient for your recipe, then zero the scale and you can add your next ingredient. No need to measure anything any longer!

There are a host of uses for these scales, some of the most common are baking bread and cakes but there are many more such as home brewing, weighing postage and kids science projects.

#2 ZERLA Digital Kitchen Scale

zerla-digital-kitchen-scale

Runner up in the kitchen scales section is the Zerla. In the sales blurb it says the scales are designed to help you eat healthier meals. To be honest that just isn’t the case, knowing the weight of your food is essential in knowing what you are eating but you will only eat more healthy meals if you buy more healthy ingredients and cook them in a more healthy way. But nonetheless, if your portions are being measured properly then there is less chance that you will be overeating as long as you have the willpower to stick to a weight-loss program.

The design is compact and lightweight making these extremely portable and versatile, use these anywhere – at home or even bring them into work with you to check your portions. The large screen is very easy to read and isn’t obstructed even when using larger bowls. The buttons are intuitive and very simple to understand, one for power / tare and the other to switch between units. Another positive is that the top slides off for easy cleaning. These digital kitchen scales measure very accurately and precisely, right up to 11 lbs and right down to one gram (0.05 oz).

Like all of the other scales in this review, the Zerla has a tare button to automatically deduct the weight of the container and reset to zero after each ingredient is added so that you don’t need to mess about with cups and measuring jugs. Unlike some of the other models however, the Zerla is very accurate at measuring right down to the lowest weight. If you are going to be weighing very small quantities and you want reliable accuracy, then this should probably be your first choice.

The scales are supplied with batteries and comes with a full 30 day money back guarantee backed by the manufacturer and you can return them for any reason if you are not 100% satisfied.

 

#1 Etekcity EK6314 Digital Multifunction Food Kitchen Scale,11lb 5kg, Stainless Steel (Batteries Included)

etekcity-digital-multifunction-food-kitchen-scale

 

Our top pick in the kitchen scales category offer a high degree of accuracy combined with a sleek, modern design at a price that you might not believe for such a great piece of kitchen equipment. You will be happy to leave these scales out on the counter such are their great looks. The sleek design makes it a breeze to clean these scales, they offer all you could ask for your kitchen weighing needs – perfect for cooking and baking as well as measuring out exact portion sizes for meal preparation if you are on a diet program.

Another growing use for the Etekcity EK6314 kitchen scales is for weighing parcels for shipping and sending out. If you are going Amazon or eBay or any other home based business. These scale measure precisely, down to 1g or 0.1oz for extremely accurate measurement and this can be important for saving you money. Make sure you are not paying shipping fees for a higher weight category than you need to! These kitchen scales feature precision one gram resolution strain gauge weight measurement. This measuring system uses four highly accurate sensors, a level of technology that you wouldn’t expect to find in such an inexpensive item.

Constructed from glass and finished in attractive brushed stainless steel, the scales are easy to clean and maintain thanks to the anti-fingerprint technology.

Another benefit of the EK6314 is the Easy-tare function. You can use this button to subtract the weight of your container so that you only measure the weight of the contents. this is invaluable when weighing loose or small ingredients or items like rice or flour or small loose items like nuts or candy as well as liquids or chemicals and drugs. Also, zero reset via the easy tare function to save you preparation time by allowing you to mix ingredients in the bowl without doing any calculations, easy unit conversion for swapping between grams, milliliters, pounds and ounces, ability to measure volume as well as weight and low battery warning light, auto turn-off if the scales are left unused, overload indication, backlit display for easy reading of scale.

There is great customer feedback on Amazon for these scales, nearly 1000 buyers have left an impressive score 4.4 out of 5

Negative points to consider
Nothing much to report here, there’s a suggestion that the unit can be a bit heavy on batteries if you use it a lot but that’s not exactly a big problem really, you would expect the batteries not to last as long if you were using them more. And there’s a low power indicator so you should never get caught unaware.

Introduction

There are many uses for glass bottles in scientific laboratories, the type of glass used being dependent on the particular requirements of the application. The use of glass as a material for lab bottles is becoming less common due to the range of plastic substitutes available – which are virtually unbreakable and cost far less – but sometimes only a glass bottle will do for the job.

Glass has the advantage of being more non-reactive as well as having good heat resistant properties and being transparent. In laboratories bottles are usually used for storing samples and reagents but the items below also have more general uses that they can be put to. There is a wide range of glass bottles available in all of the popular sizes from half an ounce up to 16 ounces to cater for most needs, let’s take a look at what we think are some of the best buys around with our review of the top 5 picks…

#5 1oz Amber Boston Round Glass Bottle with Fine Mist Sprayer

1-oz-amber-boston-round-glass-bottle-with-fine-mist-sprayer

The highly rated 1oz Amber Boston Round Glass Bottle with Fine Mist Sprayer comes in a box of 12 (boxes of 6 also available) and is equally at home in the scientific lab as it is in its alternative use in the home, kitchen and garden. This is a sturdy bottle that can withstand some robust treatment due to the good quality thick glass it is made from and is great for transporting small quantities of liquid when travelling as it will fit easily into any purse or bag. The amber color protects the bottle’s contents from the light. The tight fitting lid gives a great secure fit and will not leak or loosen in normal use.

The sprayer is longer than the bottle and can either be cut to the desired length or even better be left a bit longer than the bottle to make sure it sucks up every last bit of the liquid. The sprayer produces a very fine mist due to the small spray hole and if it is to be used domestically for spraying oil for example (it actually comes with a sample of oil), the hole can easily be enlarged with a needle to produce a better spray. Other uses are facial oils, face toner sprays, hair treatments, aromatherapy, essential oils, homemade hand sanitizer, air fresheners, throat sprays, perfumes, peppermint oil, disinfectant spray, insect repellents, after sun spray and cosmetics.

The bottle is available with a choice of either a black or white screw top lid and sprayer and as well as this 1oz size it is available in a bigger 2oz version.

 

#4 16oz Amber Glass Bottle with Trigger Spray for Essential Oils

16oz-amber-glass-bottle-with-trigger-spray-for-essential-oils

The 16oz Amber Glass Bottle with Trigger Spray for Essential Oils comes in a pack of 6 bottles and is made from actinic glass which is amber (darkened brown) in color. This is the most popular color for dark storage bottles as it will block ultraviolet light and infrared radiation which makes it perfect for protecting light-sensitive contents in scientific labs but also ideal for a whole range of other uses.

The inert nature of the glass means that there will be no reaction between the material of the bottle and its contents which means that the essential oils won’t be harmed by long term storage and also the bottle won’t break down through time. As well as essential oils these handily sized bottles are great for chemicals, health and beauty care such as facial lotions, perfumes, hair treatments or aromatherapy as well as for many other oils that you want to spray or mist over a specific area.

Many buyers of these bottles also use the to spray atomized cooking ingredients in for example cake decoration or around the home and garden for use in insect and pest control or cleaning using natural and home-sourced products. Remember if you are going to be using these bottles in multiple applications to get some self-adhesive labels to mark them with.

Introduction

A lab stirrer (or lab mixer) is used for mixing fluids. There are two distinct types of stirrer – the magnetic stirrer and the overhead stirrer. The magnetic stirrer produces a magnetic field to rotate a stir bar that stirs the fluid in the container on the plate. The overhead stirrer is dropped into the liquid container as an agitator – similar to the way a food mixer works. A magnetic stirrer is quieter and more efficient than a motorized stirrer as it has no moving parts to break or wear out. The stir bar is also small and easy to clean and because it has no lubricants there is no chance of contamination.

Used in scientific and manufacturing applications, there are almost endless applications for these pieces of kit: from making yeast starters for home brewery to biodiesel production, food and drink to stirring cultures.

Here are the best 5 stirrers and mixers you can buy on Amazon right now, starting with number 5…

#5 Scilogex 86152003 Model MS-PB BlueSpin Classic Analog Magnetic Stirrer with Plastic Plate, 100/240V

bluespin-classic-analog-magnetic-stirrer

Our first choice is the Scilogex 86152003 analog magnetic stirrer, it’s a simple, basic stirrer for higher volume use as it has a 3 liter capacity. A stir bar is immersed in the liquid and a rotating magnetic field causes the stir bar to spin and stir the liquid. The speed is adjustable using the knob on the front and the built-in electronic speed control ensures that a constant speed is maintained, even when the load changes. The high magnetic adhesion keeps the load firmly fixed to the plate during use. Requires a 100/240V power supply.

#4 Seesii Mini Magnetic Stirrer Mixer with Stir Bar

Magnetic Lab Stirrer,2000ml 4000RPM, Fast Stirring, Anti-Slip, Powerful Lab Mixer for Laboratory, Classroom, Scientific Research, Home DIY

If you want a fast, efficient magnetic stirrer that has a wide speed range but comes in a small, efficient package, look no further than the The Seesii. This impressive stirrer is perfect for use in a multitude of applications and locations. The sleek, ergonomic design lines make the Seesii perfect for the kitchen or for making homebrew beer and wine or for use in your DIY projects. It is equally at home in a science laboratory or workshop or in educational settings like classrooms and school labs. Despite the small compact design, the Seesii magnetic stirrer is powerful enough to easily handle light industrial applications and can be used in health and medicine, scientific research and even in certain agricultural applications.

The stirrer plate is large and can accommodate a wide range of vessels and glassware with a capacity of up to 2 litres. Quality of construction is extremely high and materials are of lab quality which makes the instrument sturdy, durable and gives it a long life. The controls are easy to understand and offer the owner fast, intuitive adjustment. The unit is anchored by foot pads that are designed to be non-slip and prevent movement whilst the stirring is in operation.

Another use for the stirrer which is not widely known is for decanting wine. At low speed the Seesii creates a whirlpool that gently agitates the wine allowing air to permeate it and bring out the flavors to the best effect.

 

#3 Anzeser Magnetic Stirrer Magnetic Mixer

The Anzeser magnetic stirrer has proved to be a very popular buy and has an 88% customer approval rating on Amazon from 450 ratings. The stir plate has a larger capacity than some comparable units at a full 3 liters capacity when mixing water based solutions and is the number one rated stirrer on the site.

The Anzeser is suitable for use in home, school, industrial and educational environments. At home use it for food preparation, home brewing, mixing paint, wine making and a host of other applications. School applications include for example experiments in a science class or laboratory. The Anzeser magnetic stirrer is also highly suitable for light stirring operations in agriculture and industry.

Buyers have generally found the Anzeser stirrer to be a good buy for the money and a very positive feature is that the unit will not slip, even at the highest speeds which to be honest can’t be said for all magnetic stirrers and especially in this price bracket.

Negative points to consider
—————————
There have been a few isolated complaints from users that the mixing capacity quoted isn’t quite the 3 litres that is quoted by the manufacturer. However this might well be due to buyers using the stirrer on liquids that are too viscous and not suited to the stirrer. Obviously if the liquid is too thick, more energy will be required to achieve the correct mixing and if the liquid is too viscous the stirrer cannot mix the full 3000ml capacity. Overall impression is that this unit is cheap and works but if you need more power, buy a more powerful machine!

 

#2 Duda Energy mags Aluminum HJ-1 Magnetic Stirrer for Use with Magnetic Stir Bars, 2400 RPM

Input Power 110v – 120v AC, rotating Speed 0-2400 rpm (stepless).

Discontinued Items that may still be of interest

Overhead Mixer Stirrer 100w by CB – NOW DISCONTINUED

 

Secondly we have the Variable Speed Overhead Mixer Stirrer from CB. This is different from the magnetic type of stirrer in that it has a conventional motor powering a mixing shaft which is lowered into the substance that is being stirred. This type of stirrer is perfectly suited to the classroom or small lab for mixings samples, buffers and solutions, in formulation, research and development, and clinical research. Easily moved between locations due to its small dimensions, even with the stand the whole unit only weighs 17 lbs. Power supply: 110V. Speed: 0-2000 rpm. Timer range: 0-120 minutes.

Hanna-Instruments HI310N-1 Speedsafe Heavy Duty Magnetic Stirrer- NOW DISCONTINUED

hanna-instruments-hi310n-1

Our next selection is the Hanna-Instruments HI310N-1, an excellent heavy duty stirrer with a capacity of 5 liters. It’s a bit more expensive than the smaller capacity models but if you need production-level power then this is the right choice for you. This machine is ideal for use in a laboratory as well as in a production environment. Speed range is from 100 rpm to 1000 rpm and the speed can be regulated from an electronic control panel on the machine. Control of speed is important on higher capacity stirrers like this one so there is a high-speed limiter (Speedsafe) and a VCO cut out device to prevent acceleration if the load is removed from the plate. Not only that but anautomatic feedback maintains the selected speed electronically when the load or viscosity of the fluid changes. The unit is supplied with magnetic stir bar, 115 VAC power supply, 316 stainless steel cover. (Also available, the cheaper HI300N-1 which can stir up to 2.5 liters).
