Milk is a mixture of fats, proteins, electrolytes, hormones and other ingredients. It is not pure so the question does not apply.
A lactometer is used to measure the specific gravity of milk, which helps determine its quality and potential adulteration. It can identify added water or removed fat in milk. The lactometer test is a simple and quick way to assess the purity and richness of milk.
Milk is tested to see if it has microbes by sending a sample to a lab. There are a number of local health departments that send out people to check up on this. They return with small samples that are streaked on plates and put into an incubator and then checked in 1-2 days to see what grew. Since milk is produced from the udders of cows, there will be small numbers of microbes.
It is recommended to use a modafinil test kit to verify the authenticity and purity of modafinil supplements.
One way to test the purity of a silver plate is to conduct an acid test using nitric acid. Another method is to conduct a density test to compare the known density of silver with the measured density of the silver plate. You can also use a silver testing kit that contains different solutions for testing the purity of silver.
You can test the presence of protein in milk using the Biuret test. This test involves adding Biuret reagent to the milk sample, which reacts with proteins to give a purple color change. The intensity of the color change is proportional to the protein concentration in the milk sample.

milk represents purity
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.

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 tests are used to determine the extent to which a particular substance is what is claimed. A classic purity test for gold is nitric acid; if the item being examined reacts to the acid it is not gold, or at least not pure gold.
Ephedrine can show a false positive for amphetamines on a drug test.
lacto meter is a device which is used to detect the purity of milk
A lactometer is a simple device used to measure the density of milk, which is correlated with its fat content. By placing the lactometer in a sample of milk, the reading can indicate whether the milk has been diluted with water or has had fat removed. A lower reading suggests the presence of added water, while a higher reading indicates the removal of fat.
