About Simport T301-4A Cryovial Internal Thread Design

Designed for safe storage at temperatures as low as -196°C (but should be used only in the gas phase of liquid nitrogen). Only 1-1/4 turn of the cap is sufficient to screw the cap on the vial. The specially formulated silicone O-ring ensures a positive leak-proof seal at all temperatures. Closure and vial are both made of polypropylene having the same coefficient of expansion, ensuring 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 (Series T312) and are compatible with most storage systems. Only the non skirted vials can be centrifuged, and up to 17, 000g. Sterilized by gamma radiation and packaged in unique tamperproof, resealable, safety-lock bags of 100. Autoclavable.
