CryoKING 2.0 mL cryogenic vials are designed for ultra-low-temperature biological sample storage. They are manufactured from medical-grade polypropylene (PP) and can withstand repeated freeze-thaw cycles.
The vials feature an external screw thread. According to the product information, the external-thread vial caps do not contain O-rings, which helps reduce the possibility of contamination.
Versions with a side barcode and laser-printed digital identification code are available for convenient sample identification and information storage. Versions without a side barcode are also available.
The vials are supplied sterile and are DNase-free, RNase-free, endotoxin-free and foreign-DNA-free. They remain stable from -196°C to 121°C and are suitable for vapor-phase liquid nitrogen storage.
