DEVICE FOR DEHYDRATING AND/OR EMBEDDING SAMPLES

摘要

A device for dehydrating and/or embedding preferably frozen samples, consisting of a dewar vessel (1) filled with liquid nitrogen (2) and a metal component (4) of a good heat conducting material secured to the base, the upper end of which in the base region of the dewar vessel neck has a cover (5) with a metal cooling surface (6, 7) which corresponds to matching lower contact surfaces of the thermostatically heated (9, 10) substitution (PLT) container (8) or the lower part of a freeze-drying chamber in such a way as to ensure good heat transfer between the corresponding surfaces.
