The Langlier (or Langelier) Saturation Index, LSI, of water indicates whether hard water will precipitate Calcium Carbonate deposits, dissolve Calcium Carbonate or be in equilibrium based on it's pH value and the saturation pH.
[caption id="attachment_11445" align="aligncenter" width="396"] Hard water holding Calcium Carbonate and other minerals can deposit these as solids when the LSI value...
The quality of water used has a huge effect on the quality of the beer produced. Several different parameters are key when brewing, all of which have different effects on the final product. For example Sulphate brings out the bitterness in hops, Chloride can enhance the flavour in low concentrations, but can give a medical taste in high amounts, and Calcium lowers the pH which contribute...
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...
