Technical field
The utility model belongs to technical field of experiment equipment, more particularly to a kind of centrifuge tube.
Background technology
Centrifugation technique is mainly used in the separation and preparation of various biological samples, and biological sample suspension is contained in centrifuge tube
In the case where high speed rotates, due to huge centrifugal action, make molecule such as precipitation of organelle, large biological molecule etc. of suspension
With certain velocity sedimentation, so as to be separated with solution, plastic centrifuge tube is one of consumptive material most-often used in Bioexperiment,
Due to the material character of plastics, existing plastic centrifuge tube is yielding, and service life is short；It is provided with mostly on plastic centrifuge tube anti-
Only sample leaks and lid, and sealing effectiveness is poor between the lid and body of prior art, have impact on the security of experiment.
For example, Chinese patent literature discloses a kind of centrifuge tube [application number：201520828994.6], the centrifuge tube bag
Body is included, wherein, it is provided with the body gradually increased along the length direction arranged for interval and filtering accuracy of the body
Multiple filter elements, the inner chamber of the body is divided into multiple centrifugal chambers.
Above-mentioned scheme improves the subproblem of prior art to a certain extent, and still, the program is also at least present
Following defect：Body is yielding, and sealing effectiveness is poor.
The content of the invention
The purpose of this utility model is in view of the above-mentioned problems, providing a kind of centrifuge tube.
To reach above-mentioned purpose, the utility model employs following technical proposal：This centrifuge tube, including body, its feature
Be, described body top have opening, and described body be located at open one end outer circumferential be uniformly provided with it is some to
The convex rib of lower extension, adapter sleeve is arranged with the convex rib, and described adapter sleeve is connected with capping, institute by soft even flat tube
The convex rib bottom stated has the first stopper protrusion for preventing adapter sleeve from departing from convex rib, and it is recessed to be provided with arc in the inner side of adapter sleeve
Groove, the top of described convex rib have the second stopper protrusion that can be mutually locked with arc groove, and described capping is provided with
And the ring packing structure sealed when capping covers to opening.Being arranged on the convex rib on the outside of body can strengthen
The structural strength on body top, prevent when body from taking and deformed upon when centrifuging, the ring packing knot between capping and opening
Structure can effectively prevent the sample in body from leaking, and adapter sleeve can be axially moved along convex rib, when reducing sampling
Cover the interference to sampling.
In above-mentioned centrifuge tube, described ring packing structure includes the sealing ring being arranged in capping, and described
The diameter of sealing ring is more than open diameter, is provided with what is be engaged with sealing ring on the inside of the second described stopper protrusion
Annular seal groove, the top of described sealing ring is provided with positions seal with open diameter identical.
In above-mentioned centrifuge tube, the outer circumferential of described capping offers at least one gap slot.
In above-mentioned centrifuge tube, the hardness of described convex rib is more than the hardness of body.
Compared with prior art, it is the advantages of this centrifuge tube：Simple in construction, body structural strength is high, sealing
It is good.
