Our cryogenic tubes are engineered to protect your most sensitive biological samples during long-term storage at ultra-low temperatures. Made from high-strength, laboratory-grade materials, these vials deliver exceptional durability and reliability in cryogenic freezers, vapor-phase LNâ‚‚ systems, and other extreme cold environments.
Designed with a self-standing base for effortless handling and organization, each tube also features a precision-threaded screw cap with an integrated sealing system to ensure absolute leak prevention—even under drastic temperature fluctuations. Available in 1 mL to 5 mL capacities, they offer versatility for a wide range of research, clinical, and biobanking applications.
- Ultra-durable construction: Engineered to withstand extreme cryogenic temperatures without cracking, warping, or compromising sample integrity.
- Secure screw-cap sealing: Precision threads and sealing rings ensure leak-proof performance during freezing, transport, and thawing.
- Self-standing design: Flat-bottom base allows for easy benchtop use and stable freezer storage without racks.
