Digitial refractometers measure the degree at which the light changes' direction when passing through a sample. This is called the angle of refraction. A refractometer takes the refraction angles and correlates them to refractive index (nD) values that have been established. This is then used in various industries to determine the concentration of a solution - the key to note is that the ...

This has a high importance in the livestock industry as colostrum milk is a...
A. Yes it is possible to differentiate between ethylene glycol and propylene glycol using both refractive index and specific gravity.
You will need:

In today's busy laboratory manufacturers look towards sample measurement automation to speedup analysis in a bid to improve workflow. This makes the whole production more efficient and maximises profits.
Normally refractometers are used in a single use mode and reading times are typically less than one minute, but in some circumstances automation can give rise to higher productivity by reduc...
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...
