Description
Technical field
The present invention relates to abstraction technique field, in particular to a kind of centrifuge tubes with liquid separation function.
Background technology
Extraction is one kind in the widely applied experimental technique in the fields such as chemistry, chemical industry, biology, medicine.During the experiment,
It usually needs to carry out acceleration centrifugation to experimental subjects by centrifuge, mixed solution is promoted to be layered in a short time.Experiment at present
The test tube that room uses is mostly sealed bottom, it is impossible to be used in liquid separation；The separatory funnel used is also only used for liquid separation, it is impossible to be used in
Centrifugation.It is a considerable link in experimentation to centrifuge liquid separation, various due to presently used test tube and separatory funnel
Drawback so that the centrifugation liquid separation of mixed system seems sufficiently complex, and a large amount of time is caused to be wasted in above centrifugation liquid separation, and
And can not achieve the effect that be kept completely separate, prodigious waste is caused, to make the accuracy of experimental data substantially reduce.It is existing
There is common centrifuge tube to cause extracting solution loss serious when being centrifuged off fat, resultant error is big, can not achieve and is detached from bottom
The function of liquid need to use disposable plastic tube to be drawn from top, take consumptive material when being centrifuged off fat.Publication No.
The Chinese invention patent of CN106861786A disclose it is a kind of can liquid separation centrifuge tube, be made of tube body and switch member, middle pipe
Circle drum plunger shaft arranged at body bottom, and plunger shaft upper and lower ends are small, intermediate projections, and bottom also has conduction hole, conduction hole connection
Tube body space and plunger shaft side wall, switch member top be with the matched circle drum piston of plunger shaft, have fluid channel in switch member,
Fluid channel is connected to piston side wall and switch member bottom, complicated, makes difficult, and when use is inconvenient, and cannot be real-time
Understand the numerical value of extracting solution, it is difficult to meet the requirement of experimenter.
Invention content
The technical problem to be solved by the present invention is to solve the problems, such as to mention in background technology, providing one kind having the function of liquid separation
Centrifuge tube.
In order to solve the above technical problems, technical solution provided by the invention is：A kind of centrifuge tube with liquid separation function, packet
Tube body is included, the top of the tube body is equipped with the card slot for fastening centrifuge, is equipped with flexible in the tube bottom of the tube body
