Cryogenic Vials for Ultra-Low Temperature Sample Storage Material: USP Class VI PP tube + HDPE cap Sterility: Non-sterile / Gamma / E-beam / EO Seal: Screw cap with sealing ring Cleanliness: DNase/RNase-free, non-pyrogenic Autoclavable: Yes What Are Cryogenic Vials? Cryogenic vials (cryovials) are specialized laboratory tubes designed for ultra-low temperature storage of biological samples, including -80°C freezers and liquid nitrogen environments (-196°C). They are widely used in: Cell cryopreservation Biobanking Molecular biology Clinical and pharmaceutical laboratories A cryogenic vial is engineered to ensure: Leak-proof sealing Chemical resistance Stability under extreme temperatures Key Features of Hawach Cryogenic Vials 1.

Best Practice Prepare sample with cryoprotectant (e.g., DMSO) Fill cryogenic vial (avoid overfilling) Use controlled-rate freezing (~ -1°C/min) Store at -80°C Transfer to liquid nitrogen vapor phase Vapor phase storage is recommended to reduce contamination risk. FAQ Are all cryogenic vials suitable for liquid nitrogen? Only vials rated for -196°C should be used, preferably in vapor phase storage. What is the difference between internal and external thread? External thread reduces contamination risk, while internal thread provides stronger sealing. Are the vials sterile? Both sterile and non-sterile options are available, including gamma, E-beam and EO sterilization. Can cryogenic vials be autoclaved? Yes, they are autoclavable at 121°C. What volumes are available? From 0.5 mL up to 5 mL depending on design and series.
