Cryogenic vials are the ideal choice for long term storage of sample in the harshest environments. These thick-walled tubes are outfitted with silicone O-rings that allow them to maintain their seal at temperatures as low as -196°C. Sterilized by gamma irradiation, MTC Bio cryogenic vials are designed to hold, store and preserve biological materials for days, weeks, years, or decades.
