The cap and tube of the Cryogenic Vials are made from the same material so with temperature change, they shrink and expand in unison ensuring an equally secure seal both at room temperature and low cryogenic temperatures. Large writing areas accommodate more written sample information and graduations for easy visual volume assessment. Self-standing CRYO tubes can be easily used for benchtops. Blank, nonsterile and uncapped tubes are available in bulk for less demanding applications. They are made of medical-grade polypropylene. Samples can be stored in liquid nitrogen (-80°C). We offer conical bottom cryovial tubes, self-standing cryovial tubes, external spiral cryovial tubes, and internal spiral cryovial tubes.
