CRYOVIALS, INTERNAL THREAD WITH SILICONE WASHER SEAL

These Cryovials are 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 of liquid nitrogen. A silicone washer between cap and vial ensures a positive leak-proof seal at all temperatures. A 1-1/4 turn of the cap is sufficient to seal the vial. The closures and vials are both manufactured of polypropylene having the same coefficient of expansion, which further enhances the leak-proof qualities of these vials at changing temperatures.

Vials have a white marking area for sample identification and are compatible with most storage systems. Only the round bottom vials can be centrifuged up to 17,000g. Vials are sterilized by gamma radiation and are packaged in unique, tamper-proof, re-sealable safety-lock bags of 100 pieces. Autoclavable.
