A hydrometer is an instrument which is most commonly used for testing the density of a liquid in relation to water. Hydrometers are used in many different sectors and industries as well as being a popular instrument that can be used in the home. They are usually made of glass and consist of a cylindrical stem with a printed scale and a bulb weighted to make it float upright. The correct scale r...
A. Yes it is possible to differentiate between ethylene glycol and propylene glycol using both refractive index and specific gravity.
You will need:
Digital refractometer for glycol, hydrometer 1.000-1.500 with subdivisons 0.005, hydrometer jar 300x50mm

A hydrometer measures the specific gravity of liquids. It looks at the ratio of the density of the liquid it is placed in compared to the density of water. They are usually made of a glass cylindrical stem adjoined to a weighted bulb which floats when placed in solution. By carefully placing your hydrometer in a sample of your solution you can take the measurement on the scale where it breaches...
A hydrometer is an instrument that is made of glass and consists of a cylindrical stem and a bulb weighted with mercury or lead to make it float upright. It is used to measure the Specific Gravity (SG) of liquids. In other words the ratio of density of the liquid to the density of water.The SG of water is 1.000 at 4°C. For example the lower the density of a substance the farther the h...
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...
