Description

Small-volume cryogenic tubes often fail in everyday workflows: caps are difficult to identify, tubes tip over during handling, or packaging is too rigid for flexible sample preparation. This tube is designed for routine reliability without adding workflow complexity.

Designed for routine cryogenic storage and flexible laboratory workflows, these standard cryogenic tubes provide reliable sealing, clear volume indication, and convenient handling in bag-packed format. The external screw cap with a blue concave design ensures secure closure while supporting easy operation and quick identification.

Manufactured from high-quality polypropylene, the tubes feature a self-standing bottom structure for stable placement during use. The integrated volume scale supports accurate sample measurement, while the sterile, bag-packed format enables flexible usage in bulk handling scenarios such as sample preparation, storage, and transport.
