How do you test the purity of milk using Archimedes principle?

Lactometer is a device used for finding the purity of a milk sample. It works on the principle of Archimede's principle that a solid suspended in a fluid will be buoyed up by a force equal to the weight of the fluid displaced. If the milk sample is pure, then the lactometer floats on it and if it is adulterated or impure, then the lactometer sinks.

How to test purity of mawa or khoya?

Khoya/ Mawa is sweet evaporated milk used in many Indian dishes. These evaporated milks are readily available throughout India but many people choose to make their own at home due to purity problems with store bought versions. The purity of the milk can be tested with a lactometer, though these aren't really made for home use.

Purity of milk is measured by which instrument?

Lactometer is used t measure the purity of milk Lactometer is an instrument invented by Mr. Dicas, of Liverpool, for the purpose of ascertaining the different qualities of milk from its specific gravity compared with water. On this subject Dr. Ure observes, that it is not possible to infer the quality of milk from the indications merely of a specific gravity instrument, because both cream and water affect the specific gravity of milk alike. "We must first use as a lactometer a graduated glass tube, in which we note the thickness of the stratum of cream afforded, after a proper interval, from a determinate column of new milk; we then apply to the skimmed milk a hydrometric instrument, from which we learn the relative proportions of curd and whey. Thus the combination of the two instruments furnishes a tolerably exact lactometer."

How do you make lactometer?

A lactometer is an instrument used to measure the specific gravity milk; that is, the ratio of the density of the milk to the density of water. You can use a closed ended glass tube that is graduated. Milk is poured in and allowed to stand until the cream has formed, then the depth of the cream deposit in degrees determines the quality of the milk.
