Eppendorf Centrifuges and Sustainability

In 2023, the 5910Ri and 5427R Eppendorf centrifuges became the first centrifuges worldwide to receive the ACT label. The ACT label resembles a nutrition label, showing how products rate in various sustainability categories. The 5427R centrifuge now uses a hydrocarbon cooling liquid, propane, in place of the hydrofluorocarbons (HFCs) to reduce HFCs environmental impact. This blog covers the cha...

Camlab Pool Testing Kits

Water testing is important when maintaining a pool or hot tub to make sure the water is safe to be in. The water can end up having too many or too little chemicals in it which can affect the pools hygiene and bacteria levels. The most frequently tested parameters are pH, chlorine (free and total), bromine, alkalinity and calcium hardness. Camlab have created water testing kits for testing thes...

Air cushioned vs positive displacement pipettes

Pipettes are used to transfer specific volumes of solutions from one place to another. These are used mainly in analytical and microbiology, cell biology, DNA analysis, PCR etc, where small volumes are used. Pipettes can come in fixed volumes or as variable volume so you can set the desired volume. Variable volume pipettes come in a particular volume range. Varied volume pipettes by Socore...

A quick guide to Classifications of Laboratory Glassware

Volumetric Glassware Laboratory glassware can be manufactured from Borosilicate and Soda-lime glass. Soda lime glass  is generally used for Class B products or where long term exposure to chemicals is unlikely. Class A Borosilicate volumetric glassware has superior thermal and chemical resistance and is better suited to glassware for storage of solutions, e.g. flasks. The use of  Class A boros...

How can I measure Turbidity?

Turbidity measures the cloudiness/haziness of a fluid. It is a key test for water quality, turbidity is caused by particles of varying size scattering/absorbing the light and creating a cloudy appearance. The turbidity of a sample will increase with the amount of undissolved solids present. Turbidity Tubes and Secchi Disks The simplest and lowest cost way to measure the turbidity of a sample ...

What is the difference between the readability and accuracy of a balance?

There are many options out there when it comes to laboratory balances. Other than the maximum capacity, one of the main differences you may have seen between balances is their readability. The term readability is often used interchangeably with terms like repeatability (precision) and accuracy. However, they each have different definitions that are important when trying to understand the differ...
