These externally threaded Heathrow Scientific Cryogenic Vials are designed to allow the user to easily fill up all standard sized cryogenic storage boxes. 100 vials can fit a standard cyrostorage box. The innovative sterile, non-pyrogenic, and non-cytotoxic vials increase freezer space by 23% compared to standard internally threaded cryogenic vials.

Each vial has extra-thick walls for puncture and rupture protection. Other features include an imprinted writing area, graduation marks, silicone rubber seal ring, and self-standing base. A distinctive lid (patent pending) opens easily with gloved fingers and is available in assorted colors, reducing the need for tags or coders. Not recommended for liquid phase LN2 immersion.
