Cryogenic Tubes
Cryogenic tubes, also known as cryovials, are designed for the safe storage of biological samples at ultra-low temperatures in laboratory, clinical, and research environments. Commonly used for cell storage, biobanking, and long-term sample preservation, cryogenic tubes are manufactured from high-quality polypropylene to withstand freezing conditions and maintain sample integrity. Available in multiple volumes and configurations, including internal and external thread designs, cryovials provide secure sealing, leak resistance, and compatibility with standard cryogenic storage systems such as freezers and liquid nitrogen storage.
Selecting Cryogenic Tubes and Cryovials for Your Workflow
Choosing the right cryogenic tube is critical for ensuring sample integrity, preventing contamination, and maintaining performance under extreme storage conditions.
Temperature resistance:
Cryogenic tubes are designed to withstand ultra-low temperatures, including storage in mechanical freezers and vapor-phase liquid nitrogen.
Thread type (internal vs. external):
External thread cryovials reduce contamination risk by minimizing contact between the cap and sample, while internal thread tubes offer a more compact design.
Material:
Polypropylene construction provides durability, chemical resistance, and stability at low temperatures.
Seal integrity:
Secure caps with O-ring or gasket designs help prevent leakage and protect samples during storage and transport.
Volume options:
Available in multiple sizes to accommodate different sample volumes and storage needs.
Graduations and labeling:
Clear graduations and writable surfaces support sample identification and tracking.
Compatibility:
Designed to fit standard cryo racks, boxes, and storage systems for efficient organization.
For most laboratory and biobanking applications, high-quality polypropylene cryovials with secure sealing and clear labeling provide reliable performance for long-term sample storage.
