Description

Technical Field

[0001] The utility model relates to the technical field of cryopreservation tubes, in particular to a cryopreservation tube and a cryopreservation tube rack thereof. Background Art

[0002] Cryotubes, also known as strain storage tubes, magnetic bead storage tubes, and magnetic bead cryotubes, are containers for laboratory sample storage, used for sample storage or transfer. Cryotube racks are mainly used to store cryotubes, and cryotubes are generally used in conjunction with cryotube racks.

[0003] At present, the existing cryotubes use a single thread connection between the tube body and the tube cap. Although the connection is tight, there is still a small gap and the sealing is not high. At the same time, the cryotubes have different specifications, and the cryotube rack is a fixed structure, which cannot cope with the storage of cryotubes of different specifications and can only be used for cryotubes of a single specification. Cryotubes of different specifications need to be matched with cryotube racks of different specifications, which increases the laboratory procurement cost. Utility Model Content
