Description
Technical field
The utility model relates to a kind of cryopreservation tubes, are a kind of micro high protection cryopreservation tubes specifically.
Background technique
Biological cryopreservation tube is one of biological scientific research, the common consumptive material of medical domain, is usually used in low temperature storage biological sample.?
In biological sample bank, cryopreservation tube is particularly critical consumptive material, mainly assumes responsibility for bio-genetic material, metabolite and all kinds of faces
Bed sample, such as the effect of tissue and the ultralow temperature storage of blood, these samples are super by be finally put into after pre-processing
It is stored in low temperature refrigerator or liquid nitrogen container.With the implementation and universal, the safety of biological sample cryopreservation tube of biological sample bank
Pollution-free storage and storage efficiency are in urgent need to be improved.
At present on the market freeze that form of tubes is different, and the main distinction is that pipe lid is outer spiral cover or inner swiveling closing, outer spiral cover
Referring to that cap wall is provided with screw thread, screws cooperation with the screw thread of tube wall, inner swiveling closing, which refers to, is provided with screw thread in pipe cover outer wall, with
The screw thread of inboard wall of tube body screws cooperation.Classical cryopreservation tube is the outward turning tube shape of round bottom, cannot independently be stood on table top, is sealed
Circle is located at pipe lid inside top and pipe shaft oral area seals, therefore when screwing, thread gaps and contacting external air exist
Microorganism enters hidden danger, be easy to cause sample contamination.With the development of cryopreservation tube, the generation of inward turning cryopreservation tube solves above several
A problem.Inward turning cryopreservation tube sealing ring is located at outside pipe shaft, avoids thread gaps and contacts with the external world.And such seal form
Leakproofness improves, and effectively reduces microbiological contamination and liquid nitrogen enters caused booster.But there is also some disadvantages, examples for inward turning cryopreservation tube
Such as pipe lid screw thread is located at pipe outer side of lid, when experimental implementation Shi Dangguan lid is placed on table top, is easy pollution threaded portion, and then dirty
The sample in pipe is contaminated, meanwhile, when cryopreservation tube is toppled over, liquid in pipe sample can enter thread gaps, cause centainly to lose.In addition,
For inward turning cryopreservation tube due to its pipe Gai Tedian, threaded upper portion is essential to re-extend a point height, clutches and uncaps for finger.With current
The development of biological detection analytical technology, sample storage small dimension, more packing have become inexorable trend, and inward turning cryopreservation tube is due to its pipe lid
Feature, whole height are apparently higher than the outward turning cryopreservation tube of same capacity, and then waste the memory space of a large amount of storage equipment.
Summary of the invention
