Celltreat's new Freeze Cryogenic Vials are designed for storing biological material at temperatures as low as -196°C in the gas phase of liquid nitrogen. Internal thread design prevents contamination and uses an O-ring silicone seal to ensure a positive seal at any temperature. External thread caps feature an integrated leak-proof seal, a long skirt for easy one hand aseptic methods, and a thread design allowing it to be removed or sealed with a 1-1/4 turn.
Vials are available with round bottoms or self-standing bottoms that interlock with Celltreat's Easy-Grip Workstation Rack to enable one-handed opening. Caps have textured ridges to provide gripping when wearing gloves. Contrasting black graduations are large and easy to view, while the large white marking area provides excellent contrast for identification. Vials are packaged sterile in self-standing resealable bags, 50 per bag.
