Thermo Fisher, 375418PK, Nunc™ Biobanking and Cell Culture Cryogenic Tubes

Nunc™ biobanking cryogenic tubes are sterile polypropylene vials for storage of biological samples in mechanical freezers and vapor-phase liquid nitrogen. This configuration has a 1.8 mL capacity, an external screw thread, a self-standing round bottom, and an integrated writing surface for sample identification. The anti-rotation base is designed to engage compatible racks, helping reduce tube movement during automated or manual capping. External threads keep the closure interface outside the sample-contact area and can simplify aseptic handling. The tubes are DNase/RNase free and sterile to a 10⁻⁶ sterility assurance level. They are suitable for storage down to approximately −150 °C in vapor-phase cryogenic conditions. This pack contains 450 tubes. Use validated cryostorage procedures and compatible closures and racks to maintain sample integrity and traceability during long-term biobanking.
