[Temperature characteristics of an object during the process of cryofixation by the "freeze--etching" technic]

When using low temperature methods for preparing water-containing objects in electron microscopy temperature characteristics of different objects was studied during freezing and defreezing depending on different preparation conditions. Temperature characteristics of the object was estimated by means of a storage oscillograph with a thermocouple connected through a transistor amplifier. The thermograms permit one to select preparation conditions of the object eliminating artefacts.
