In the food industry, pH monitoring may be required during the production or pre-production process for a number of reasons including for microbe monitoring and taste purposes. In baking and bread-making there are a number of reasons why you would wish to know the pH - having a low pH in sourdough inhibits growth of pathogenic bacteria and in bread dough pH control agents (preservatives) may be...
Testing pH in milk and dairy products is key to detecting impurities and signs of infection both upon collection of milk at the point of delivery. In the sterilization process, checking the pH is important as the lower the pH the faster the process will be. However, lower pH values in milk may also indicate that the cattle producing it may carry an infection.

pH meters are wonderful devices until they go wrong. You are then left with your sample sitting on the bench and in some instances, not knowing what is wrong. The following questions and answers are designed to help you diagnose the problem.
My pH meter won't give a fixed reading – is drifting or providing erratic...
Q: I am looking to buy a pH electrode, many of them say "Na error over..." - what does this mean?
A: Sodium error is also known as alkaline error, and is a phenomenon that occurs at very high pH levels - usually pH 12 or over.
At very basic or alkaline pH levels, where Hydrogen ion concentration is relatively low compared to the Sodium ion concentration in the sample, you can see a Sodium...
pH electrodes have many options to choose from;Â tip shape, junction type, shaft material and fill solution. A key difference is whether the electrode has a single or double junction.
How do electrodes work?
Combination electrodes work by having a sensing half-cell (AgCl covered silver wire) and a reference half-cell (Ag/AgCl reference electrode wire), these two components must be joined ...
[caption id="attachment_112" align="alignleft" width="142"] Camlab pH Electrode Soaker storage bottle[/caption]
To prevent the glass pH membrane and junction from drying out it is recommended to store your electrode in an electrode storage solution. The best solution for this is 50% saturated KCl and 50% pH 4 buffer in conjunction with a soaker storage bottle. pH buffer is used bec...
The compact Blueline pH electrode range from SI analytics covers the most important measuring applications in laboratories.
Reliable high speed settings over a wide temperature range, new membrane glass with higher mechanical stability, as well as improved gel electrolyte are only a few features ensuring improved functionality.

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...
