Heating glassware is an important topic as heat can change the volume of the glassware if the temperature used is too high. The maximum temperature for heating the glass depends on the specifications and what type of glass is used. For example, borosilicate glassware provides a lower coefficient of expansion than other glass types such as soda lime glass. Another note is that not all glassware...
2Mag have a wide range of magnetic stirrers, with some having an internal controller, and others requiring an external controller. The stirrers that require an external controller can be submersed in water baths, up to 95oC. These stirrers come with a single stirring point, or multiple stirring points.

Memmert are world-known for producing robust, functional and reliable pieces of lab equipment. Whilst their main product portfolio lies with larger pieces such as ovens and test chambers they also manufacture water baths, produced to the same Memmert level of quality. Launching at the start of 2021, the WTB range replaces the older models WNB, WNE and WPE. The WTB builds on past models, featur...
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.

A hotplate stirrer is used extensively in the lab and is ideal for mixing up and preparing solutions . The Camlab Choice range contains a selection of hotplate stirrers each combining value for money with a range of features. With five models available, you'll be sure to find something suitable for your application. As an overview, the hotplate stirrers can be grouped according to their plate ...
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...

Many laboratories use ovens to heat, dry, age, degas, cure or condition samples.
Lab ovens are usually available as natural convection or fan assisted - we've taken a look at when you would choose each type to help you pick the right oven for the task.

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.

Water baths are an excellent way to maintain samples at a set temperature, though when they are run at high temperatures or for long periods of time the water will of course evaporate.
If the bath runs dry this will not only mean your samples are out of temperature, but it can also damage the bath.
There are several things you can do to ensure this does not happen.

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...
