Osmometer from Advanced Instruments Inc., type Cryoscope 4D3.
The osmometer is used in the dairy industry to measure the osmolarity of milk by means of a freezing point determination. Because milk is a water-based solution with some suspended solid substances, it freezes at a lower temperature than water. If there is less water, the freezing point drops. This machine is used to see if there is no additional water added to the milk.
