Abstract
The utility model relates to a double-seal sperm cryopreservation tube, which comprises a plastic test tube with a screw thread port and a cover which is matched with the screw thread port of the test tube and is provided with screw threads, wherein two seal surfaces are arranged on the connector of the test tube and the cover, wherein one seal surface is a mating surface between a ring-shaped surface on the end portion of the test tube hole and the bottom of the cover, and the other seal surface is mating surface between a step surface between the tail end of screw threads of the test tube and the test tube wall and the cover, and a seal ring or a seal sheet is arranged between the mating surfaces. The double-seal sperm cryopreservation tube has the effects of totally preventing internal maters and external maters of a cryopreservation tube from exchanging, thereby thoroughly preventing the problems of cross infection by utilizing liquid or gas as an agency, and guaranteeing the safe use of frozen materials.
Description
Technical field
The utility model relates to a kind of experiment consumptive material, the frozen test tube of particularly a kind of low temperature.
Background technology
Along with the continuous maturation of cryogenic freezing technology, low temperature frozen in different field by everybody institute's extensive use.And be the frozen pipe that places sealing by frozen liquid, described frozen Guan Zaicong normal temperature is down then after being stored in-196 ℃ the liquid nitrogen, the sealing property existing problems, and causing with the liquid nitrogen is that the cross-infection problem of media also displays gradually.
Summary of the invention
The utility model main purpose is to overcome the deficiencies in the prior art, thereby a kind of good seal performance is provided, and stops the inside and outside mass exchange approach of frozen pipe fully, prevents with the liquid nitrogen to be the frozen pipe of double containment seminal fluid of cross-infection problem of media.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the frozen pipe of a kind of double containment seminal fluid is characterized in that: comprise threaded mouthful plastic test tube and the screwed lid that matches with the screw thread mouth of described test tube; There are two sealing surfaces the junction of described test tube and lid: one of them face is the ring surface of test tube mouth end and the mating surface between the cover bottom; Another face is the screw tip of test tube and the mating surface between step surface between the test tube wall and the lid mouth; Between the described mating surface encapsulant is arranged.
The technical solution of the utility model can also be further perfect,
As preferably, the screw thread of described test tube mouth is an external screw thread, between described externally threaded end and the test tube wall outer step surface is arranged; Described lid is an internal thread.
As preferably, the screw thread of described test tube mouth is an internal thread, and interior step surface is arranged between the end of described internal thread and the test tube wall; Stating lid is external screw thread.
As preferably, it is characterized in that: described bottom surface in vitro is a taper seat.
As preferably, it is characterized in that: described bottom surface in vitro is a hemisphere face.
As preferably, described test tube is transparent or semitransparent body, and tube wall is provided with gage mark.
As preferably, described encapsulant is sealing ring or diaphragm seal.
As preferably, described test tube internal diameter is 8-20mm, and clear height is 30-80mm;
As preferably, described frozen pipe capacity is 1-5ml
Therefore, the utlity model has the effect that stops the inside and outside mass exchange of frozen pipe fully, thoroughly prevent with the freezing liquid to be the cross-infection problem of media, guaranteed the safe in utilization of frozen thing thereby reach.
