The present invention relates to an apparatus for freezing samples such as tissue specimens, particularly for rapidly freezing multiple specimens without the need to sequentially prepare and freeze each sample individually. The apparatus comprises a mold which can accommodate one or more tissue samples, a hands-free means for supporting the mold, an insulated container for holding a cryogenic material or refrigerant, and an optional cover for the insulated container. The invention also relates to methods for freezing the tissue specimens.
