By DWK - Wheaton Science Products
These vials/ampules help reduce sample contamination due to their ultimate tamper-evident seal. Glass cryogenic vials are designed for preserving biological materials with liquid nitrogen. They are made of Wheaton® low extractable borosilicate glass, which meets ASTM Type I Class A and USP Type I standards. The special design allows for storage at low temperatures as well as rapid thawing. Pre-scored ampules eliminate filling.
