Vials designed for exceptional ease of use and sample integrity in ultra-low temperature storage. Closure seals without gasket or O-ring, minimizing risk of contamination. The deep skirt of the closure allows single-handed aseptic technique without exposing fingers to vial contents. Ribs around the bottom of the vial interlock with wells in the Cryovial Racks so the vial will not turn when opening or closing. Bottoms of vials are skirted; vial stands without holder.

Sterile vials and closures are pre-assembled and radiation-sterilized. A white marking area, fill line and graduations are printed on the side. Certified sterile, non-cytotoxic and non-pyrogenic.
