These Cryovials are designed for safely 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. Only a 1-1/4 turn of the cap is sufficient to seal the vial. The specially formulated silicone o-ring ensures a positive leak-proof seal at all temperatures. 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, can be color coded by using a CAPINSERT™ (Series CLS-4767) and are compatible with most storage systems. Only the non-skirted 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.
