The LABSOLUTE® cryo tubes are designed for the optimized storage and preservation of biological sample materials in the gas phase of liquid nitrogen or in deep-freeze devices. The cryo tubes are produced under clean room conditions as defined by ISO 14644-1 Class 8 and US FED STD 209 Class 100000 from high-quality PP.

The screw caps made of HDPE with integrated sealing surface are innovative and especially practical. Leaks from the cryo tubes are therefore 100 % guaranteed not to happen - incorrectly positioned O-rings are a thing of the past.

The cryo tubes are available in various sizes and with inner and outer threads.

• Certified sterility through beta irradiation
• Free from human DNA, RNase, DNase, ATP and pyrogens
• Large labelling field
• Simple removal and secure storage: supplied in a handy dispenser box with 10 resealable pouches of 50 cryo tubes

A 2D data matrix, which corresponds with the linear barcode on the vessel side, is integrated in the vessel bottom of the tubes. The dual identification enables secure tracking and facilitates handling of large numbers of samples. Tubes lock in cryo boxes and cryo racks.
