Celltreat FREEZE round bottom 4.5 mL cryovials with internal threads. Use these cryogenic vials to store mammalian cells in gas phase liquid nitrogen (-196°C), for example.
Threads on the inside of the cryocap help prevent contamination.
Celltreat internally-threaded screw top cryovials have a working volume of 4.5 mL, are graduated up to 4.5mL in 0.1mL increments, have bold graduations and a white marking area.
Cryovials are made of polypropylene, are sterile, autoclavable, DNase- and RNase-free and nonpyrogenic. Caps have ridges that make opening and closing cryovials easier, and contain silicone O-rings that produce tight seals.
Vials come packed in self-standing resealable bag, 100 vials/case.
