摘要：For the controlled cooling of specimens which are at least partially of liquidform, especially biological specimens, it is important that crystallization at the freezingpoint takes place locally, without supercooling, and preferably with absorption of thelatent heat of fusion. At a temperature which is a predetermined amount above a givencritical temperature for the specimen, e.g. its freezing point, a Peltier effect module isenergized to effect supplementary cooling at a local area, for example one end of thespecimen. The Peltier effect module and the specimen in its container supported in asample holder are relatively movable. Preferably, the module is displaced, this beinginitiated by the insertion and removal of the sample holder, preferably by directmechanical engagement.
