Changes in temperature affect a pH reading. This is why you will usually see the temperature printed on the side of the bottle of pH buffer solutions. The buffer will be closest to its stated pH at that temperature (usually 20oC or 25oC)
When calibrating a pH meter with automatic buffer recognition, it is recommended to use the correct buffer. So please check the manufacture's instructions ...
pH Buffers are aqueous solutions with well defined pH values and have a 'buffering' capacity to maintain pH even when small quantities of acids or bases are added to them. Having a known pH value, buffers can be used as a standard to calibrate pH Meters and therefore keep on-going measurement taking accurate and reliable. To keep these statements true you need to make sure your buffers are in d...

I have some pH buffer capsules which I make up into liquid pH buffer solutions for calibrating my pH meter and I wondered what is the shelf life once it is made up?
The reagecon buffer capsules are a simple way of extending shelf lifes of pH buffers. the powder is made up to a speci...

We often get asked about supplying NIST buffers, however we offer both NIST buffers and Buffers which are traceable to NIST standards. They are different products so here is a simple guide to the differences.
NIST buffers: NIST is the National Institute of Standards and Technology, an agency of the U.S. Departmen...

The effects of Temperature on pH measurement are usually not well understood by the user and temperature has a range of effects on your measurement...
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...
