Property part backwards to fixing seat one end with operation shank mutually fix.
As further preferred, the elastic component is spring.
Preferably, the fixing seat is equipped with the positioning column for preventing elastic component from deviating from.
Preferably, the pipette further includes connecting tube, the connecting tube is vertically arranged with tube body, the one of the connecting tube
End is connected with tube body, and the other end is connected with accommodating chamber.
Preferably, the accommodating chamber is arranged in parallel with tube body.
Preferably, fixing seat upper surface is equipped with the sideboard for preventing spring from laterally twisting.
Preferably, the lateral wall of tube body is equipped with scale.
The utility model has the following beneficial effects:
In the present invention, experimenter can pull the piston rod in accommodating chamber, make when needing to carry out pipetting
It obtains the tubular body being connected with accommodating chamber and forms a negative pressure, the process of imbibition can be completed.Experimenter can slowly downwards
Pull piston rod, the volume of transfer liquid to control.When tube body has drawn default liquid volume, it can push up
The liquid that pipette is drawn can be transferred in cell therefor by piston.Reality can be greatly reduced by using the pipette
The operating time of personnel is tested, but also the liquid volume measured is more accurate.
Detailed description of the invention

Specific embodiment
The present embodiment provides a kind of technical solutions:
As depicted in figs. 1 and 2, a kind of pipette facilitating operation including the tube body 1 for accommodating liquid and provides negative
Pressure is with the liquid absorption device for imbibition；The liquid absorption device includes hollow and open at one end accommodating chamber 31, piston and piston
Bar 32, the accommodating chamber 31 are connected backwards to the one end at opening position with tube body 1, and the piston is slideably positioned in accommodating chamber
Empty internal, the piston rod 32 is mutually fixed with piston.
As shown in Fig. 2, the open end of the accommodating chamber 31 is equipped with the lid 33 for preventing piston from deviating from, it is correspondingly, described
Lid 33 is equipped with the through-hole passed through for piston rod 32.
As shown in Figure 1, the lid 33 is equipped with fixing seat 34,34 upper surface of fixing seat backwards to one end of accommodating chamber 31
It is fixed with elastic component 35；The piston rod 32 is fixedly connected with operation shank 320 backwards to one end of piston, operates shank 320
It is arranged perpendicular to piston rod 32；Elastic component 35 is fixed backwards to one end of fixing seat 34 with operation 320 phase of shank.
In the present embodiment, the elastic component 35 is spring.
As shown in Figure 1, the fixing seat 34 is equipped with the positioning column 340 for preventing elastic component 35 from deviating from.
As shown in Fig. 2, the present embodiment further includes connecting tube 2, the connecting tube 2 is vertically arranged with tube body 1, the connecting tube
2 one end is connected with tube body 1, and the other end is connected with accommodating chamber 31.
As shown in Fig. 2, the accommodating chamber 31 is arranged in parallel with tube body 1.
