CryoSure® brand vials are recommended for storing cell cultures, blood/serum specimens, sperm, and other biological specimens at vapor phase* liquid nitrogen temperatures (-320°F/-195°C).
By using external threads, all CryoSure® vials are designed to be less susceptible to aerosol contamination than internally threaded vials.
The specially selected copolymer is nearly transparent and provides superior tensile strength and resistance to gamma radiation sterilization.
Polyethlyene screwcaps feature a molded-in sealing ring for rim-seal that provides a leakproof closure without the use of a silicone gasket. Caps are available in natural, green, red, blue, yellow, orange, lavender and white.
*Evergreen does not recommend the use of screwcap vials, including CryoSure® vials, for immersion in liquid nitrogen or other liquified gases. Immersion in liquid nitrogen may cause leakage in CryoSure® vials and also presents the potential danger of rapid pressure buildup and/or explosion when returned to room temperature. Please use CryoSure® vials in the vapor-phase only.
