CV301 Series Internal Thread with Silicone O-Ring Seal

The CV301 series of cryogenic vials are defined by the specially formulated silicone o-ring which ensures a positive seal at any temperature, even at cryogenic temperatures. Caps and tubes are pre-sterilized and are certified RNase, DNase, Pyrogen and DNA-free. Because the tube and cap are both made from polypropylene, they both have the same coefficient of expansion which ensures a leak proof closure over changing temperatures. The caps can be color coded using a cap insert.
