Abstract
A freeze dryer for rapidly and efficiently drying tissue specimens, having a source of heat independent of the cover and mounted for efficient heat transfer to a copper support plate having a substantially flat top surface. A specimen plate is machined from aluminum to have a recessed bottom surface which is matable with the support plate for maximum physical contact. The specimen plate has peripheral walls of a thickness and a height that will eliminate substantially all heat differentials between different portions of the specimen plate interior caused by external variations to allow effective control of the temperature of the specimen plate.
