Test papers and strips are a great way to measure pH for those who need a fast and low cost option.
We've explored the key differences between these two types of tests below, and looked at what advantages each brings.
What is pH test paper?
Test papers are one continuous piece of paper which is soaked in indicator to show a particular pH change.
These may be in booklets where yo...
Pasteurisation (or pasteurization) is used in a range of liquid food and drink products to kill bacteria, making it less quick to spoil. In milk this process is especially important - a recent study by the Centre for Disease Control (CDC) in the USA showed that the risk of a disease outbreak was 150x greater from unpasteurized or "raw" milk than pasteurized milk.

How can I detect Nitrite in meat
In Europe many meat products like ham and smoked pork chop are cured. Curing is a process to preserve meat and sausages by addition of common salt. The meat develops a typical curing taste and becomes red in color. This process is important to avoid a grey coloration and a growth of microorganisms. However the reaction of nitrite with amino acids, can cause t...

AdBlue is the brand name of a 32.5% aqueous urea dilution. Truck engines with SCR catalytic technology use AdBlue to reduce the NOx-content in the exhaust gas stream. This reduction is necessary to reach the demanding limits for exhaust gases. The exact composition of AdBlue is defined in DIN 70070.
AdBlue is filled into a separate tank. Fuel in the AdBlue tank will permanently damage or d...

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...
