2ml external thread polypropylene cryodense cryovial self standing base rnase and dnase free sterile

CryoDense vials are designed for cryogenic storage and transport of biological specimens at temperatures as low as -196°C. The unique, slim-profile design of these external thread tubes and caps allow for more density of storage in racks, maximizing valuable cold storage space. The slim design also allows easier handling while storing or pipetting. The CryoDense lip seal closure requires only a half-turn to obtain a positive seal with less torque than other brands. The seal obtained is secure and virtually leakproof. The vials are tested and certified leakproof to 95kPa . A star-shape design at the base makes these vials stable on the benchtop and locks into place with our accessory storage boxes and other select boxes and racks for one-hand operation Not for use in the liquid phase of Liquid Nitrogen
