As of June 2022, Cole-Parmer have undergone a rebrand of some of their brands and equipment in order to be more efficient. The units themselves have remained the same but the design and model numbers have been updated to fit the Cole-Parmer theme. Below is a list of some brands that have been rebranded and an overview of their new model numbers.

Stuart by Cole Parmer have recently given their trusty Undergrad hotplate and stirrer range a modern new look! Replacing older models, the new and updated Undergrads feature robust tough outer casing to prevent damage caused by knocks. They come in a clean blue and white colour scheme.
The entire Undergrad range comprises of analogue magnetic stirrers, analogue hotplates and a choice of an...
Hotplates or combined hotplate stirrers are used in most laboratories for basic heating and stirring applications.
Many models are offered with either a ceramic, ceramic coated or aluminium top plate. But what is the difference?

Sand baths have been used in labs since the time of alchemists. Simply, a sand bath is made by placing a container on a heated surface and filling with sand. A vessel to be heated is then submerged into the sand which conducts the heat from the heated surface into the sides of the vessel. In modern labs, sand baths are still used and are typically set up using a hotplate or heating mantle on to...
Some hotplates and hotplate stirrers have the ability for you to be able to connect an external temperature probe. The function of the external temperature probe is so that you can monitor and control the temperature of your heated sample. This is in contrast to simply controlling the hotplate surface temperature.

There are a variety of stirrers available for laboratory use, each having their own qualities which make them more suitable for certain applications than others. Below is an outline of the types of stirrers available and what they are more suitable for: Magnetic Stirrers Magnetic stirrers use a rotating magnetic field to cause a stirrer bar (of flea), immersed within a l...
"Pure" water is used in all types of laboratories for a range of uses - from making up calibration standards to cleaning and even in the rinse cycle in some laboratory glasswashers for a pure clean. There are different types of purified water available - but what is the difference?

Stuart have launched a new vortex mixer, the mini SA6 model with a robust casing and variable speed control, this mini unit is ideal for chemical and bioscience laboratories alike.
Â
Vortex mixers are widely used in bioscience laboratories, and are particularly useful for life science researchers studying cell cultures and microbiology.
Chemical labs also rely on vortex mixers everyday...
Melting point tests provide a fast and simple method to verify the purity of solid samples in the lab after synthesis or in manufacturing as a quality control check.
Preparing the samples correctly will ensure results are accurate and comparable. We've taken a look at the proper way to prepare samples for melting point analysis below.

Introducing the new Automatic Melting Point Apparatus from Stuart - the Watch as your samples melt live on screen or leave it to complete the melt analysis independently and then observe the play back post-melt. During post melt review additional measurement tags can be added if required, such as meniscus point or the automatically obtained result can be overwritten. Up to approx 300 melt v...
Q: I need a roller mixer, but our lab works with tubes and bottles in different sizes - what would you recommend? A: The Stuart range of roller mixers would be ideal. These have recently been updated, and are now more flexible than ever - letting you use one unit to mix small centrifuge tubes right through to larger bottles [caption id="attachment_7537" align="aligncenter" width="300"] Th...
Thanks for sharing such a great information.. It really helpful to me.. I always search to read the quality content and finally i found this in you post. keep it up!
I came across your article about "DPD Tablets" on Camlab Info, and it's a valuable resource for anyone seeking information about water testing and analysis using DPD tablets. Your explanation of their usage and significance in water quality monitoring is quite informative.
This article on nanocolor tube tests is a gem for analytical enthusiasts. The idea of zero calibration is intriguing, and your detailed explanation makes it accessible. The step-by-step process helps demystify the technique for beginners like me. The use cases you've highlighted, particularly in...
Grant have introduced the new Controlled Rate Freeze Thaw (CRFT), which is a liquid nitrogen and cryogen free controlled rate freeze and thaw system for cryopreservation in a wide range of applications. Cryopreservation is a process where biological materials such as cells, tissues...
A dipslide is a means of testing the microbial content of liquids. This is a common method of monitoring and measuring microbial activity within many systems and commonly cooling systems. Usually the use of a dipslide is the first line of defence for the testing of microbial issues that could be...
Purchasing items using donated funds without the burden of VAT will now save many Millions of pounds each year which can be put to better use in advancing scientific knowledge to provide new treatments and cures that will shape the medicines of the future.
Working with pressure/vacuum conditions in the lab is common but not all products are designed to withstand this. Products with appropriate geometry and wall thickness are suitable for working safely with pressure. For example, filtering flasks, desiccators, or flat flange vessels, as well as...
