The Seal’N Freeze® box allows users to freeze up to four samples simultaneously and hands-free, when used with Seal’N Freeze® Cryotray® cryomolds.
The box’s stainless-steel case and foam lining ensures optimal temperature control throughout the freezing process; and its small and compact size ensures easy storage – even in the most cluttered laboratory.
