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 you body’s cells absorb more and for less to be passed as waste.

#4 Hornady Lock N Load Sonic Cleaner II (110 Volt)
Second for review is the Hornady Lock N Load Sonic Cleaner II which is bigger in capacity than the other ultrasound cleaning systems on this page but also comes with a heftier price point to match.
The Hornady can be used for cleaning all of your brassware and also any parts of a gun that need a good cleaning.
The internal size of the cleaning tank is 7.25″ x 6″ x 3″ which is twice as wide as others on the market and provides a volume capacity of 2 liters. The process is aided by an 80 watt ceramic heater built into the unit that helps to agitate the operation and remove more dirt more quickly.
The timer for the cleaning cycles are a bit longer than the smaller, lighter models and range from 5 minutes up to 30 minutes.
The Lock N Load seems to be the ultrasonic clening system of choice for gun owners, through a combination of the heavy-duty heater-assisted cleaning system and the large extended capacity of the holding tank. Other uses include cleaning of gun cartridges, small car parts, nuts and bolts.
A great chice for you if you need a higher capacity heavy-duty cleaner and are willing to pay a bit more for the increased performance.
#3 iSonic D3800A-S+1OZ Digital Ultrasonic Cleaner, Silver color with chrome plated trims, 1.3Pt/0.6L, 110V, Sample Solution Included
The next one up on our list for review is the iSonic D3800A-S+1OZ Digital Ultrasonic Cleaner which is available in white, silver or pink. Not the largest capacity in this range at 20.3 ounces (600ml) and with an internal volume of 6.1″ x 3.7″ x 2.0″ but the iSonic will handle all your jewelry items and household items with ease.
It will clean deep into all these awkward areas like small holes and crevices in your rings and bracelets. iSonic differs from some manufacturers in that it recommends that you use a cleaning solution in water with your ultrasonic cleaner. This is entirely optional and many users have reported great results using only tap water or a little drop of washing-up liquid.
The cleaner features a digital timer that has 5 different time settings – 90/180/280/380/480 seconds and a manual on/off switch. Your items will be shining brightly like new
You should beware of any coatings that you might have on your glasses ans the ultrasound process can disrupt it and may cause the coating to flake or peel.
A good all-round choice with plenty of positive feedback from happy customers and a very decent buy at the price.
Unfortunately for overseas customers, the iSonic does not ship to international addresses, delivery is only within the US.
#2 Famili FM8000WW Ultrasonic Polishing Jewelry Cleaner with Digital Timer for Cleaning Eyeglasses Rings
Runner up in the ultrasonic cleaner section is the Polishing Jewelry Cleaner from Ultrasonic. Bring out the best in your tired looking jewelry with this highly efficient and low-noise cleaning system.
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 is using water, the cleaning process bombards the object at high speed 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 ti would be a surprise if you ever needed to use it such is the reputation for reliability that the FM800WW has.

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.
The following are some recommendations of what we consider to be the best electronic kitchen scales on the market at the moment…
#5 Ozeri Pronto Digital Multifunction Kitchen and Food Scale, Elegant Black
These are traditional round shaped scales and look great in a range of exciting colors to match any kitchen decor.
The main things that distinguish the Pronto is their accuracy for weights up to 11 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 Pronto 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 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
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
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
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 Digital Multifunction Food Kitchen Scale,11lb 5kg, Silver, Stainless Steel (Batteries Included)
These scales 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. It features a precision one gram resolution weighing system using four highly accurate sensors, a level of technology that you wouldn’t expect to find in such an inexpensive item.
As well as cooking and baking, these are perfect for other small weighing tasks including measuring packages for posting and weighing jewelry. Finished in attractive brushed stainless steel, the scales are easy to clean and maintain thanks to the anti-fingerprint technology.
Some of the great features are: lightweight and portable, 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.

As a measuring dish it’s unequalled, not only is it very accurate, it measures in all the most commonly used units – milliliters, cubic centimeters, fluid ounces, pints, teaspoons, tablespoons and cups. Great if you find pouring into spoons to measure quantities tricky to do. One big advantage of the Emsa Perfect Beaker is that you can mix a few ingredients right in the unit by adding them in and totting up the measurements on the scale, saving time and washing up.
It is made in Germany from BPA free plastic, has a beveled rim that makes pouring both easy and drip-free and is dishwasher-safe (although some people prefer not to put plastic in the dishwasher). It can handle boiling water easily and comes in two style options – with seal or without seal, this is the Esma terminology for with or without a lid.

This set of the three most popular sizes of low form beaker is made from sturdy Class A high quality borosilicate glass which has great inert properties, meaning the beakers will not react with their contents.

Also by Karter Scientific is the 214U2 Glass Erlenmeyer Flask Set in 3 Sizes – 50ml / 150ml / 250ml. Again these are three of the most popular and practical sizes of flask in use today and are made from heavy duty high quality 3.3 borosilicate Class A glass.

#2 213A2 Karter Scientific Low Form Glass Beaker 5 Piece Set 50, 100, 250, 500, & 1000ml
Another Karter Scientific product – the 213A2 Karter Scientific Low Form Glass Beaker 5 Piece Set in 50ml, 100ml, 250ml, 500ml and 1000ml is our runner-up in this review section.

The range of sizes right up to one litre makes this set very versatile and highly useful in a lot of home and laboratory applications.
#1 213C2 Karter Scientific Graduated Cylinder
Our top pick in the Beakers and Flasks section is the 213C2 Karter Scientific Graduated Cylinder 3 Piece Set 10ml 50ml and 100ml are a bit different in that they have a hexagonal base which prevents the beakers from rolling off the work surface and smashing if they are tipped over. They also have three small dimpled feet on the bottom that they stand on, which prevents heat direct transfer to the surface you are working on and can also help to reduce mess.
Perfect for laboratory as well as home use and equally at home holding acid as they are with cake-mixing ingredients, aromatherapy products, perfumes or any small quantities. The cylinders have clear, easy to read graduated markings and have decent accuracy for a product in this price range.
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
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 OilsThe 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.

Hazardous gases can be a real danger in the home and workplace but there are various different gas detectors covering all the dangerous gases you may find. As well as gases that can cause explosions or fires, there are other deadly dangers from poisonous gases in the home. Carbon monoxide and radon are both referred to as “silent killers” as they are impossible to detect without a gas sensor, below are some great recommendations as to gas detection kit that you can buy today to keep your home, office or school safe from these killers.
#5 Kidde KN-COPP-3 Carbon Monoxide Alarm
Carbon monoxide poisoning is one of the main causes of domestic accidental death by poisoning in America but it can easily be prevented in your home by installing this Kidde KN-COPP-3 Carbon Monoxide Detector. CO gas levels can reach deadly levels without you realising it as it is an odorless, colorless gas which can be released by domestic appliances and office equipment. CO poisoning symptoms are difficult to spot and can often go undetected, being similar in nature to common illnesses like the flu. It is therefore essential to have at least one CO monitor/alarm system in place in your home – and indeed it is now compulsory in some areas. This unit plugs directly into your AC power outlet and has a battery back up which takes over automatically in the event of a power failure. Carbon monoxide levels are monitored continuously and you can see in an instant what they are on the digital display, a loud beeping alarm will sound if a dangerous level of gas is reached.
#4 UEi Test Instruments CD100A Combustible Gas Leak Detector
The UEi Test Instruments CD100A Combustible Gas Leak Detector is a professional standard instrument designed for service engineers to enable them to detect combustible gas leaks in the home and commercial premises. But at an average cost of $100 to call out a plumber or furnace repair man, the unit pays for itself in one use. This gas detecting device will pinpoint even the smallest leak, right down to which side of a joint the leak is on – even when the use of more traditional methods prove ineffective. If you use any of acetone, benzene, butane, propane, toluene, methane, ethylene, gasoline, halon, hydrogen sulfide, solvents, thinners, or refrigerants remember that there are no safety circuit breakers to trip like you would get in an electrical system. The detector is simplicity itself to use, there’s nothing complicated to try and work out, just switch it on and listen for an increase in tick rate.
#3 TIF Instruments TIFXL-1A Refrigerant Leak Detector
Refrigerant Leakage is a very serious hazard in commercial and industrial premises where refrigerators are used and to a lesser extent in the home. Indeed because of the dangers of refrigerant gases getting into the atmosphere, all refrigeration equipment needs to be properly disposed of. The TIF Instruments TIFXL-1A refrigerant leak detector can detect all halogenated refrigerants, including fluorine and is part of the new range of gas leakage equipment with the brand “Generation X”. The company says that they have completely redesigned the instrument both aesthetically on the outside and internally with a new microprocessor based operating system. The redesigned sensor tip gives increased sensitivity and reliability and sends 2000 signals per second back to the internal computer. This machine has had some very positive reports from customers and is our top rated refrigerant detector.
#2 Bacharach Leakator Jr 0019-7075 ABS Plastic Combustible Gas Leak Detector
Our runner-up selection in the gas monitoring section is the Bacharach Leakator Jr. Combustible gases such as butane, methane, acetylene and those given off by gasoline, paint thinners, solvents etc are any gas that can cause fire or explosion and can obviously be deadly in the home or workplace. This is a very compact and portable combustible gas meter at only 6 inches long, but coming complete with a 12″ extension hose for extended reach to check for small pockets of gas in awkward, hard to reach spots. Featuring dual sensitivity for detecting gas in the wider area then pinpointing a leak in a pipe for example. A fully portable unit, the Leakator gas indicator is simplicity itself to use and can pinpoint large or small leaks whilst needing no calibration whatsoever.
#1 Corentium 9800401 Digital Electronic Radon Gas Monitor
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.
The function of a laboratory water bath is to heat containers used in biomedical or pharmaceutical tests at relatively low temperatures. The heating bath works on the principle of electrical resistors raising the temperature of the liquid (water or oil) used in turn to heat the specimens. Maintenance of water baths is important and when considering buying, you should take into account the following specifications:
Material – Generally stainless steel for cleanliness and prevention of rust Coating – A high quality epoxy powder coat finish will guard against chipping to the container and is easy to clean Heating elements – Recessed and out of the way so you don’t have to come into contact with them
Seamless construction and rounded (radius) corners – Ensures strength and integrity of the unit, there won’t be any leakages from burst seams

Conductivity meters measure how well a solution can conduct electricity, this is useful in a lot of general and industrial applications. Conductivity varies with temperature and so conductivity meters have built-in temperature compensation and often have temperature measurement incorporated into the unit.
The main uses of a conductivity meter include water purification systems, boiler water, swimming pools, hydroponics (water gardening), monitoring public water quality, reverse osmosis deionization (RODI) units, fish tanks, testing well and spring water, hospitals, brewing and drink making industry.

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.

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.
