, it is necessary to which each reagent is corresponding to use a liquid-transfering gun during agent, or change, could be used after pipette tips of cleaning, Qian Zhezao
It is excessive into liquid-transfering gun quantity, take up space, influence to operate, the latter is loaded down with trivial details in the presence of operating, and experiment progress and operating efficiency is influenceed, to reality
Testing makes troubles.It is therefore desirable to prior art is improved.
The content of the invention
To solve existing liquid-transfering gun when drawing different liquids, it is necessary to configure special liquid-transfering gun, or frequent clean, replacing
Liquid-transfering gun, causes that operation is excessively cumbersome, influences the problems such as conventional efficient, and the present invention provides a kind of liquid relief of rotatable replacement pipette tips
Rifle.
The present invention is completed by following technical proposal：A kind of liquid-transfering gun for rotating replacement pipette tips, including its interior band plunger shaft,
The body of a gun of piston, and the pipette tips located at body of a gun end are provided with plunger shaft, it is characterised in that the pipette tips include and body of a gun phase
Fixture even, the matched revolving part with fixture, the fixture are provided with the piston of passage, the passage and the body of a gun
Chamber connects, and the revolving part is provided with the pipette tips of multiple insertions, will pass through the rotation of revolving part, makes the rifle of one of insertion
After passage on head face fixture, you can after pulling piston pipette tips, passage, the plunger shaft of connection is produced negative pressure, i.e.,
In smokable reagent to pipette tips, after moving to corresponding container, piston is promoted to extrude the reagent in pipette tips, rotating revolving part makes
After passage on the pipette tips face fixture of another insertion, the suction of another reagent can be completed again, so can be quick
Pipette tips are changed, and same pipette tips can repeatedly draw same reagent.
Extend in the middle part of passage self-retaining part on the fixture to edge and bottom, i.e. the interior upper end of passage is located at
Fixture top, and be connected with body of a gun plunger shaft, the outer lower end of passage is located at fixture bottom, and penetrated with revolving part
Pipette tips are matched but are not attached to.
The pipette tips penetrated on the revolving part are arranged at intervals multiple, the pipette tips upper end rotation of each insertion along revolving part periphery
Go to matched with the passage on fixture behind position but be not attached to, lower end is hanging.
Through hole is provided with the revolving part center, bearing is provided with through hole, the fixture is short provided with extending downwardly
Axle, the short axle lower end is spirally connected through the bearing in the through hole and through hole at revolving part center with nut, will pass through short axle and spiral shell
Revolving part is fixed on fixture by mother, and revolving part is rotated around short axle, to realize the replacing of pipette tips or rotation.
The fixture and revolving part are set to cylinder or polygon cylinder.
Groove is provided with the pipette tips of each insertion on the revolving part, sealing ring is provided with groove, it is close will pass through
Seal prevents reagent from leaking outside.
The present invention has following advantages and effect：Using such scheme, it is convenient to, easily rotate revolving part, make it
In an insertion pipette tips face fixture on passage after, you can pull piston to make pipette tips, passage, the plunger shaft of connection
After producing negative pressure, you can in suction reagent to pipette tips, after moving to corresponding container, promote piston can be by the reagent pressure in pipette tips
Go out；After being rotated further by the passage on the pipette tips face fixture that revolving part penetrates another, another reagent can be completed again
Suction, so can quick rotation pipette tips, the displacement of different reagents is completed, without the frequently replacing body of a gun, and same pipette tips can be more
It is secondary to draw same reagent, without cleaning every time.After sticking different labels on the pipette tips outer wall wall of multiple insertions in addition,
Corresponding reagent can be directed to be aspirated, effectively prevent wrong suction reagent.Liquid relief efficiency is not only increased, and is ensured correct
Operation, ensure that experiment is safe and reliable, quick.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The present invention is described further below in conjunction with the accompanying drawings.
The liquid-transfering gun of pipette tips is replaced in rotation provided by the invention, including interior be provided with of band plunger shaft 11, plunger shaft 11 is lived in it
The body of a gun 1 of plug 2, and the pipette tips located at the lower end of the body of a gun 1, the pipette tips include the fixture 4 being connected with the body of a gun 1, with fixture 4
Matched revolving part 5, the fixture 4 are provided with passage 3, and the passage 3 connects with the plunger shaft 11 of the body of a gun 1, described
Revolving part 5 is provided with the pipette tips 6 of multiple insertions, and the middle part of 3 self-retaining part of passage 4 on the fixture 4 is to edge and bottom
