Lip Seal Tubes
Designed for storage of biological material, human or animal cells, at temperatures as low as 190°C. The cap features a long skirt for one hand aseptic techniques, a super fast thread

design that allows tightening or removal with a mere 1.25 turn, and an inside thread design that will not contribute to possible contamination.

A specially designed lip inside the cap ensures a leak proof seal even at low temperatures. The closures and tubes are both manufactured of polypropylene having

 the same coefficient of expansion, which further enhances these leak proof qualities.

The tubes are provided with a white marking area for sample identification. This lip seal tube is compatible with most storage systems. The vials are sterilized by gamma irradiation and are packaged in a unique tamperproof, resalable, and safety-lock bags of 100.
