TENAK SlimTube cryotube

Traditional external-thread cryotubes allow only 9 x 9 storage in standard cryoboxes. TENAK’s latest cryotube allows users to increase their cryotube storage capacity by 23%.

The SlimTube is only 12 mm in diameter, allowing the storage of 100 tubes in a 10 x 10 array in a standard cryobox while retaining the external thread to ensure no sample contamination. By adding 23% more samples into a freezer, the cost per sample is reduced by up to 20%.

The tube and cap are made from specially formulated medical-grade polypropylene, with equal coefficient of expansion for a secure seal from bench down to cryogenic temperatures. The cap’s steep thread allows a half-turn opening and the star-foot base ensures the tube is self-standing and compatible with standard workstations for single-handed operation.

There are two level indicators to show appropriate filling levels for -80°C and -196°C storage to improve safety and reduce the risk of overfilling the tubes. The tube has a white-printed write-on labelling area for manual identification.

SlimTubes are supplied in self-standing resealable bags of 100 tubes and are free of DNA, DNAse, RNA, RNAse and ATP. They are available in five sizes — 0.5, 1, 2, 4 and 5 mL — and three double-sided cap inserts (with two colours each, making a total of six colours) aid sample identification.
