Abstract
The invention concerns a device for metallic mirror-cryofixation and subsequent cryopreparation of biological materials for microscopic, in particular electron microscopic examinations, employing a highly polished metallic mirror cooled to very low temperatures by a cryogen and mounted in a metal freezing chamber, which can be flooded with a gaseous cryogen, on which an object can be placed by means of an injection mechanism or the like, wherein the freezing chamber has an adequate volume for cryopreparation and for accepting the required accessory devices.
