摘要

A freeze dryer includes a freezer unit having a plurality of walls defining a freezer interior. A housing defining a chamber suitable for receiving a specimen to be freeze dried is mounted to one of the panels to extend through an aperture therein into the freezer interior. A lid engages the housing to seal the housing. A condenser and a pump are coupled to the housing to lower pressure in the chamber and to condense liquid from the specimen.
