how would you test for milk in a milk chocolate bar

The test ring in a heat exchanger is the seal, that keeps the water from the heating container. The test ring should be changed every year.

The phosphatase test in milk measures the amount of phosphatase enzyme in the milk. The phosphatase enzyme should be inactivated by pasteurisation. If the phosphatase test is not negative, there is a problem with pasteurisation or recontamination with unpasteurised milk.

Milk will not help you pass a drug test.
