Introduction

There is a vast range of titrators available at prices ranging from under $100 to over $10,000 depending on manufacturer, quality and accuracy. Top of the range are the excellent titrators from Mettler Toledo and you can see their full range here.

We review some of the best titrators on the market below, starting with number 5…

#5 Mettler Toledo 30470855, EasyPlus EPM Titrator

mettler-toledo-30470855-easyplus-epm-titrator

First up in our reviews we have one of Mettler Toledo’s mid price-range titrators and although still on the pricey side, this is comes highly recommended.

The c features Easy EPM, a process that produces semi-automated titration by presetting the sequence of operations all the way through titration. Standard laboratory tasks including the preparation and dispensing are taken care of with ease.

Color change of samples indicate that titration has been achieved by means of the automated burette and the dispensing tip is immersed in solution to avoid errors.

The unit has a number of built-in calculations that can be preset for ease of operation and error-free results every time. Analysis can be done either via the built-in touch screen or remotely using the wheel controller that is attached through a USB port on the unit.

International unit conversion means that the Mettler Toledo can be used in any country equally effectively.

 

#4 Cole-Parmer Titration Kit; Burette, Clamp, Stand, Beakers, Stirrer, and Stir Bar

cole-parmer-titration-kit-burette-clamp-stand-beakers-stirrer-and-stir-bar

The Cole-Parmer Titration Kit is a Do-It-Yourself titrator, Cole-Parmer took all of their best selling titration components and compiled them into this titrator kit. The package includes glass burette, double-burette nickel-plated zinc clamp holder, lab stand with porcelain base (chemically resistant) and aluminium rod, compact magnetic stirrer and stir bars, and five beaker in the most common standard sizes (50, 100, 250, 600, and 1000 ml). Also included are a burette brush and stir bar retrievers for cleaning up after the titration.

All of this in one convenient titration kit, so rather than have to source each one individually you get them all in one go and you can be 100% confident that the component parts all work together well to produce great results every time.

The only thing that you will need to buy in addition is the titrant to add to your sample.

This is an excellent high quality kit that is perfect if you need to do titration experiments on a budget and costs a fraction of some of the top of the range lab titrators.

The instrument supports pre and end point titration, manual titration and also preset blank titration. It will remember a user’s previous settings and produce an individual mode based on that, 50 different sets of data can be stored. The Mxbaoheng ZDJ-4A also supports pH measurement and calibration.

Interface with external equipment is through an RS232 port, you can connect the unit to a printer or to an external computer so that you can operate it remotely.

The package includes burette, silver, platinum, pH single bridge and double bridge electrodes, pH buffer powders.

 

#1 YSI 285230620, TitroLine 5000 Automatic Titrator with 50mL Dosing Unit and Magnetic Stirrer, Certification Included

ysi-285230620-titroline-5000-automatic-titrator

Our top pick is the YSI TitroLine 5000 Automatic Titrator,

What we like about the TitroLine 5000 titrator is that it makes it easy to achieve perfect titration results every time whether or not you have any experience in carrying out titration experiments. The instrument takes away any need for in-depth training or specialized knowledge, with the Titroline, titration is child’s play. Results are quick and always accurate.

Based on a syringe burette and an intelligent meter to analyze the high resolution pH and millivolts, the parameters of titration are built in to the programs of the intelligence and executed for you at the press of a button.

The built-in standard methods cover acidity, alkilinity, chlorine and FOS/TAC. Electrode types covered are ORP, sliver, pH and mV electrodes.

The Titroline 5000 is ideally suited to commercial and industrial applications as well as being invaluable in the lab. Typical uses range from wastewater management and analysis through food chain analysis with hundreds of other potential applications in between.

 

 

Introduction

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. Although these are budget-priced instruments, they have been calibriated in a science lab for accuracy.

There are some great instruments for sale at the moment on Amazon, let’s take a look at our top five, beginning with number 5…
