Cryogenic vial racks are capable of withstanding the extreme freezing temperatures required for stabilizing samples to study overall behaviour. Offered in various well place quantities, the supports securely hold common sized vials to allow for one handed capping. Alphanumeric indexing moulded on the coloured surface assists with correct post-operation identification. Autoclavable cryogenic vial racks may feature stacking abilities to give more working space or open bottoms for draining.
