You Searched For: Osmometers
Osmometers determine the total solute particle concentration in physiological and biological liquids. Using the common freezing point of the solution depression method, the osmolality is reached by introducing a serum sample to the cooling chamber to reach a temperature below the expected freezing point. A small sample of osmotically active particles are taken to freezing point for precisely measuring the colligative property. Then the sample is stirred for partial crystallization. The on-board computers in osmometers can recall a set number of past tests for easy comparisons.
