CRYO TUBES - “external thread” – “sterile”

Designed for the optimised storage and conservation of biological material, human and animal cells at very low temperatures in the gas phase of liquid nitrogene or in cryogenic freezers.

Manufactured from ultra clear, high grade polyropylene by fully automatic,  human touch free machines.. Higly polished interior wall guarantees low liquid retention and ensures minimum sample loss.

Autoclavable at 121 °C for 20 minutes. Caps schould not be kept closed during autoclaving process. Otherwise tubes can be deformed.

Cryo tubes are manufactured in germ-free , class 10.000 sterile production areas and then re-sterilised by gamma irrediation.

Tubes are supplied with a certificate as a guarantee of “DNase, RNase & pyrogen free” product.

Since both cap and tube are made of same material with same coefficient of expantion secure seal at all temperatures is quaranteed.

External thread  cap design alllows %28 more free space in the tube in comparison of internal thread cap design.

Caps are featured with cavities for different colored cap inserts which enables  easy identification of tube contents.

Cap inner design ensures hermetical and leak-proof closure Silicone washer inside the cap ensures  positive sealing at any temperature and prevents leakege.

Caps can be opened and closed with single hand. A 3/4 turn of the cap will be sufficient for full closure.

Unique star-base foot design enables free standing option. Base design allows the tube to be fixed at the cryo vial racks. Tube caps can be opened by single hand without the need of picking up the tubes.
