CRYOPRESERVATION BY MEANS OF A GASEOUS OR VAPOROUS COOLING MEDIUM

摘要

Disclosed are methods for producing frozen samples (1), particularly for cryopreserving biological samples, comprising the following steps: liquid samples are provided by means of a drop generator (10); said samples are cooled in a cooling device (20, 21, 22) by means of a cooling medium until at least the surface of the samples freezes; and the samples are collected in a receiving device (40). The samples are frozen in the cooling device (20, 21, 22) by means of a gaseous or vaporous cooling medium. Also disclosed are devices especially for cryopreserving biological samples.
