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. ‘M ‘and ‘W’ which is divided in three parts and marked as 3, 2 and 1. That indicates the level of the purity in Milk.

# Step 3- If the milk is mixed in water then it would sink higher then marked ‘M’.

# 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.
