Made of polypropylene, Deltalab’s 4ml Non-Sterile Skirted Cryovials with External Thread are designed for the storage and transportation of biological material. The external thread design provides a smooth and uniform inner surface, thus reducing the risk of contamination.
The tubes can be autoclaved to 121°C and withstand temperatures down to -190°C. The closures and tubes are both manufactured of polypropylene having the same amount of expansion, which further enhances their leakproof qualities at changing temperatures.
Each cryovial withstands centrifugation up to 17,000xg. The skirted tubes are not recommended for centrifugation.
The caps suitable for these cryovials are supplied separately.
