In addition, centrifuge tube all just is used as centrifugal action at present, and in the production practices of reality, need the multi-step synthetic operations such as centrifugal, extraction, cultivation, particularly in some biochemistry and chemical reaction, as carry out under at aseptic condition being interrupted, in the operation of successional multi-step, the simplified operation process is directly cultivated in test in centrifuge tube, reduce the risk that fluid exchange causes cross pollution.But present centrifuge tube all can not be cultivated, but by fluid exchange, increases the other flow process of cultivating together.
The utility model content
The purpose of this utility model is: for the problem of above-mentioned prior art existence, a kind of multipurpose centrifuge tube that can cultivate as required in centrifuge tube is proposed, the utility model has been simplified the cultivation operating process, reduces the risk that fluid exchange causes cross pollution.The utility model can be under high temperature, high pressure, high speed conditions, energy effective sealing, Leakage prevention.
To achieve these goals, the utility model is taked following technical solution:
A kind of centrifuge tube, described centrifuge tube partly is made of pipe shaft and end cap, it is characterized in that: an end of described pipe shaft is blind end, described blind end was formed by the pipe end, was taper, camber or platybasic type at the bottom of the described pipe; The pipe shaft other end is openend, described openend is comprised of ozzle and neck, and described neck wall ratio pipe shaft wall thickness is large, and described neck connects pipe shaft and ozzle, described ozzle stretches out at circumference and forms the boss larger than neck diameter, and described boss and centrifuge tube supporting arrangement cooperate supporting; Described end cap part is comprised of aluminium-plastic cap and plug, the barrel portion that described plug is extended by intermediate layer part periphery straight down by discoid summit portion, than the little intermediate layer part of discoid end face diameter and two is integrally formed, described discoid summit portion and aluminium-plastic cap interference fit, described intermediate layer diameter is than described ozzle hollow bulb diameter large 5% to 10%, described two barrel portions are contained in the neck, the intermediate layer part of plug, two barrel portions and neck interference fit; Described aluminium-plastic cap is provided with grip portion and holds the holding portion of the discoid summit portion of described plug, and described aluminium-plastic cap can separate with plug.
Like this, discoid summit portion and aluminium-plastic cap interference fit when plug, by the rotary aluminum-plastic lid plug is filled in ozzle, by test, when the diameter of the intermediate layer of plug and two barrel portions than ozzle hollow bulb diameter large 5% to 10%, can the effective sealing pipe shaft and can conveniently open, closed, when covering plug, two cylinders and neck interference fit, at high temperature, high pressure, under the high speed conditions, the energy effective sealing, effectively Leakage prevention utilizes closely cooperating of plug and pipe shaft, can prevent the cross pollution of centrifuge tube, described ozzle extends to form the boss larger than neck diameter in a circumferential direction, and described boss and the cooperation of centrifuge tube supporting arrangement are applicable to need carry out under aseptic condition and can be interrupted, the course of reaction of successional multi-step can be widely used in biology, medical treatment, chemical industry, the field such as pharmacy and scientific research.Because aluminium-plastic cap and plug are separable, when needs are cultivated operation, can inject by plug.
It is that the diameter of described neck hollow bulb is set according to the rotating speed of centrifuge that the utility model further improves.More preferably, described pipe shaft is provided with scale, and design changes the scale size according to the pipe shaft amount of capacity, can be from 1ml--500ml.
It is that described plug is rubber or silica gel that the utility model further improves.More preferably, pipe shaft is transparent, translucent or opaque (such as brown, black or colour).More preferably, pipe shaft can be designed to square, throw camber or anomalistic object according to the size of design capacity and the needs of purposes.
The beneficial effects of the utility model are: centrifuge tube is under high temperature, high pressure, high speed conditions, energy effective sealing, effective Leakage prevention, utilize closely cooperating of plug and pipe shaft, can prevent the cross pollution of centrifuge tube, can carry out reliably the operations such as centrifugal, separation, extraction, cultivation; Centrifuge tube can add relevant aseptic component by asepsis injector, carries out sterile culture and other relevant aseptic work.The utility model can be widely used in the fields such as biology, medical treatment, chemical industry, pharmacy and scientific research.
