How does a freezing point osmometer work
WebFREEZING POINT osmometry determines the osmotic strength of a solution by utilizing freezing point depression. A sample is introduced to a cooling chamber where it is cooled to a temperature below its expected freezing point. The sample is stirred with a wire, which causes the sample to become partially crystallized. WebA freezing point osmometer monitors how a sample’s freezing point changes according to its solute concentration. With a precisely linear correlation between a sample’s freezing point and its osmolality, freezing point osmometry offers one of the most accurate assessments of osmotic concentration.
