Thermo Scientific Nalgene Cryogenic Vials have an externally-threaded closure to facilitate sterile aseptic technique. A deep-skirted HDPE screw closure provides the best seal possible without the use of a gasket or o-ring.
Choose plain or graduated vials, which include a white marking area, fill line and graduations. Closures and vials are non-cytotoxic, nonpyrogenic. Available radiation sterilized (caps preassembled) or nonsterile.
Excellent for vapor-phase liquid nitrogen storage
