Where in today’s world there are chances to take impure milk for any sources like dairy booths, dairy shops, marts and many more. So there is necessity to check milk purity because of availability of impure milk in market. As we know there are lots of substances which make milk impure and we can check or test that impure milk through lactometer. What is Lactometer Lactometer, a cylindrical vessel made by blowing a glass tube. One side of glass tube looks like a bulb with filled by mercury and another site is thin tube with scaled. For milk testing lactometer dipped in milk which we are testing. In lactometer the point up to which it sinks in the pure milk is marked after that put in water and marked at the point up to which it sinks in water. It sinks less in milk then water because as we know milk is denser then water. At lactometer there are to portions i.e. which is divided in three parts and marked as 3, 2 and 1. That indicates the level of the purity in Milk. Here below some steps mentioned for milk testing # Step 1- Whenever you want to test the milk purity, you just put the instrument or lactometer in milk. # Step 2- If it sinks up to the mark which mentioned at lactometer that means milk is pure or if not that means milk is impure. # Step 3- If the milk is mixed in water then it would sink higher than marked. # Step4- If it stands at the mark 3 that means milk is 75% pure and respectively 2 for 50% purity and 1 means 25% purity. It is scientifically observed that the cases of skimmed milk the lactometer fails to provide correct results if the density of skimmed milk is made equal to pure milk adding water. Conclusion- Lactometer is useful for milk testing by which anyone can measure their milk purity easily. It’s necessary to eat or drink healthy for a healthy life.
