Availability: In stock



Volume: 5.0ml

Cap Design: O-ring seal and internal threads

Designed for storing cells, blood, serum and other biological fluids at temperatures as low as -196 °C, these sturdy polypropylene vials offer a high level of chemical resistance but should be used only in the gas phase of liquid nitrogen.

A positive leakproof seal enhanced by a silicone o-ring around the cap.  As the cap is tightened the o-ring compresses between the tube wall and the cap, creating a tight closure.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. 12.5x90mm

Sterilized by gamma radiation and packaged in unique tamperproof, resealable, safety-lock bags of 100. Autoclavable.
