Including：Sample collection, sample preparation (pretreatment), sample measurement, result calculating and data analysis.Lab analysis automation is contained
Lid scope is wide, and step completion whole-course automation is unrealistic, what automation experiment chamber system was still realized step by step stage by stage.Sample system
Standby process is the step that labour is most intensive during normal assay, and Sample Preparation Procedure automation is important step, sample system
Liquid relief liquid feeding in standby is most basic operation.Liquid relief filling operation is realized draws a certain amount of liquid from a container, turns
Move on in another container, during Multi-example preparation, liquid relief filling operation is realized, accurate quantification removes solution and in space
The liquid-transfering device for being related to multiple structural forms is accurately positioned in position.Patent CN201220355596.3 discloses a kind of automatic shifting
Liquid device and Multi-example preparation work station, the problem of device is present be：When the liquid level inductor of pipette top and bottom goes out
During existing problem, then liquid relief error occurs or liquid relief can not be completed, in addition, other perforate sets lift adjustment on pipette
Bar so that the processing cost of pipette is higher, and therefore, for problem above, exploitation is a kind of reasonable in design, convenient and practical
Semi-automatic quantitative liquid-transfering device is those skilled in the art's technical problems to be solved.
The content of the invention
The technical problem to be solved in the present invention is：To overcome the technical problem mentioned in above-mentioned background technology, one is now provided
Kind Semi-automatic quantitative liquid-transfering device reasonable in design, convenient and practical.
The technical solution adopted for the present invention to solve the technical problems is：A kind of Semi-automatic quantitative liquid-transfering device, the device
Including：Liquid storage bottle, it is arranged on the screen pack of bottom in liquid storage bottle, be arranged between screen pack and liquid storage bottle bottom of bottle Z-shaped first
Drain pipe, the three-way pipe being connected with the first drain pipe by the first valve, with three-way pipe is connected by the second valve second goes out
Liquid pipe, three-way pipe top are connected with pipettor, and pipettor includes：The liquid relief bubble and liquid relief bubble inwall being connected with three-way pipe top
The shim of abutting, through liquid relief anti-overflow pipe in the middle part of top and shim steeped, with shim be connected and be fixed on outside anti-overflow pipe
The fixing end of wall；First valve and the second valve are connected by circuit with controller.
Further limit, fixing end described in above-mentioned technical proposal is connected with anti-overflow pipe outer wall by taper thread.
Beneficial effect：Compared with prior art, the structure design of Semi-automatic quantitative liquid-transfering device of the invention is relatively reasonable,
It is convenient and practical without installing liquid level inductor respectively up and down without the perforate setting lowering or hoisting gear on pipette in addition, suitably enter
One step popularization and application.
