The Precision Systems Cryoscopes are precision instruments that automate the measurement of freezing point depression of solutions. A simple adjustment of the cooling bath temperature of the Wide Range Cryette implements the measurement of freezing point depression of solutions with freezing points in the range of – 10 to +10° C. Depression of the freezing point of a solvent is directly proportional to solute particle concentration, and is generally independent of the chemical nature of the dissolved material. As a result, an accurate measure of freezing point depression presents a powerful analytical tool in many application areas.
