cryoscope

plural cryoscopes

1. physicalchemistryA device used to measure the freezing point of a liquid (or the melting point of a solid).

   It has been considered preferable to adhere to the apparent freezing point as determined by a standard cryoscope, rather than to confuse matters by attempting to apply corrections, which may or may not be themselves correct.
