CRYOVIAL Silicone Washer Seal and Internal Threads

from $305.42

Designed for storing biological material, human or animal cells, at temperatures as low as -196C but should be used only in the gas phase of liquid nitrogen. A silicone washer between cap and vial ensures a positive leakproof seal at all temperatures. A 11/4 turn of the cap is sufficient to seal the vial. Closure and vials 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..A specially designed lip inside the cap ensures a leakproof seal for the CRYOVIAL even at very low temperatures.

Tubes have a white marking area, can be color coded by using a CAPINSERT (Series T312) and are compatible with most storage systems. Only the round bottom vial can be centrifuged, and up to 14,000g. Vials are sterilized by gamma radiation and are packaged in unique tamperproof, resealable, safety-lock bags of 100.
