ABSTRACT:
A drying apparatus for drying gels and biological substances has a base with a drying area, surrounded by a sealing surface, for receiving the substance to be dried and a cover, whose marginal area can be placed in vacuum-tight manner on the sealing surface and the drying space formed between the drying area and the cover can be evacuated. In order to achieve a good and reliable sealing of the drying space and to prevent the penetration of ambient air into the latter, the sealing surface in the cover bearing area and/or the marginal area of the cover resting on the sealing surface are constructed in rubber-elastic manner and at least one closed evacuatable groove is formed in the sealing surface. The cover rests on the sealing surface on either side of the groove.
