Cryovial® Series T309

Designed for storage of biological material, human or animal cells, at temperatures as low as -190ºC. The cap features a long skirt for one hand aseptic technique. Tubes are provided with white marking area for sample identification, and can be color-coded by the use of a CAPINSERT®. Super fast thread design allows tightening or removal with 11⁄4" turn. Inside thread design will not contribute to possible contamination. Vials are sterilized by gamma irradiation, and are packaged in unique tempered-proof, reseal-able, safety-lock-bags of 100, and 10bags to a case. The closures and tubes are both manufactured of polypropylene having the same coefficient of expansion, which further enhances the leak-proof qualities of these vials at changing temperatures.
