Cryovial®, Silicone Washer Seal, Tube w/External Threads

Specially Formulated Polypropylene

The tube of this vial is of the same construction as Lip Seal Design Tube CRYOVIAL. The cap features the same long skirt for easy one hand aseptic techniques, the same super fast thread design that permits it to be removed or sealed with a mere 1.25 turn, and the same inside thread design that will not contribute to possible contamination. This cap also features an exclusive silicone seal fitted at the base of the cap to ensure a positive seal at any temperature, even the lowest of cryogenic temperatures. The tubes are provided with a white marking area for sample identification and can be color coded by the use of CAPINSERT (TM). The vials are sterilized by gamma irradiation and are packaged in unique tamperproof, resealable safety-lock bags of 100.
