CRYOVIAL® SILICONE WASHER SEAL AND INTERNAL THREADS
Made of polypropylene

Designed for storing biological material, human or animal cells, at temperatures as low as -196°C but should be used only in the gas phase. A silicone seal between the cap and the vial ensures a positive leakproof seal at all temperatures. A 11⁄4 turn of the cap is sufficient to seal the vial. Closure and tubes are both manufactured of polypropylene with the same coefficient of expansion, which ensures an equally secure seal both at room temperature and at low cryogenic temperatures. Tubes have a white marking area, can be color coded with a CAPINSERT™ (cat. # T312 Series) and are compatible with most storage systems. Only the round bottom vial can be centrifuged, and up to 3 000g. Sterilized by gamma radiation and packaged in unique tamperproof, resealable, safety-lock bags of 100. Autoclavable.
The CRYOVIAL® tubes are certified RNase-free, DNase-free, Pyrogen-free and DNA-free.
