Tissue biospecimens have particular requirements for cryogenic storage. Wheaton’s CryoElite Tissue Vials were designed for the safe cryopreservation of these samples. With a wide mouth opening, 5 ml capacity and high-integrity closure, the vial meets USP Class VI classification. Lottested and certified to be free of pyrogens, RNase/DNase and endotoxins, the vials have a sample capacity of 5mL and a storage temperature range of -156°C to 121°C. The externally threaded cap is capable of maintaining a secure closure during freeze/thaw procedures. The vials have a flat bottom and a stippled external surface to promote easier handling. Wheaton
