Abstract
The utility model belongs to a get the liquid container, with supporting pipettor that uses of pipette especially that is used for microorganism, chemical analysis experiment ration to move and get various liquid. including being provided with the awl cylindric pipette interface of rubber inlayer, setting up the connector with pipette interface matched with on the lower terminal surface of piston cylinder, installing the cavity piston rod at the piston cylinder fit in, the lower extreme of cavity piston rod is uncovered, the upper end is setting up confined piston handle, the lateral part of piston handle setting up with the control valve of cavity piston rod intercommunication, the outer end of control valve is sealed, sealed lid or manual valve are being installed in the cooperation on the through -hole of control valve setting. The utility model discloses rational in infrastructure, the processing ease, can be singlehanded completion reagent move the work of getting, move the speed of getting and control easily, can avoid reagent the waste and to personnel's injury, can match with the pipette of different specifications and use, with low costs.
Description
Technical field
This utility model belongs to a kind of and takes liquid container for what microorganism, chemical analysis experiment quantitatively pipetted various liquid, particularly a kind of with the matching used pipettor of pipet.
Background technology
When microorganism, physico-chemical analysis, the substantial amounts of use pipet of experimenter pipettes liquid reagent.Use need during pipet and ear washing bulb with the use of, have that following some is not enough: (1) whole pipetting processes need two handss with the use of, one hand cannot complete operation；(2) pipette in process, will well control the capture velocity of ear washing bulb, if suction force excessive velocities, it is easy to cause that liquid flows out from pipet upper port, thus causing the injury of reagent waste and experimenter；(3) in the process of tapping, finger unclamps and blocks the bad grasp of time point of pipet upper port, it is more difficult to be accurately controlled tapping amount.Although the liquid-transfering gun having all size size in front on market is sold, but the input cost of liquid-transfering gun is costly, and different size liquid-transfering gun also needs to configure the disposable tip matched.
Utility model content
The purpose of this utility model is in that to provide a kind of and the matching used pipettor of pipet, it is rational in infrastructure, processing ease, what singlehanded can complete reagent pipettes work, the speed pipetted is easily controlled, can avoiding the waste of reagent and the injury to personnel, can mate use with the pipet of different size, cost is low.
The purpose of this utility model is achieved in that a kind of and the matching used pipettor of pipet, including the cone barrel pipet interface being provided with rubber internal layer, the lower surface of piston cylinder arranges the connector matched with pipet interface, coordinate in piston cylinder and hollow piston rod is installed, the lower end of hollow piston rod is uncovered, upper end arranges the piston handle closed, sidepiece at piston handle arranges the control pipe connected with hollow piston rod, the outer end controlling pipe is closed, and is installed with sealing lid or hand-operated valve controlling to coordinate on the through hole that pipe is arranged.
Specifically used method of the present utility model:
Before pipetting liquid: the lower end connector of piston tube is inserted pipet interface, is close to rubber internal layer, covers rod gland, hollow piston rod is pushed into piston cylinder bottom.
During imbibition: palm when held piston cylinder, pipet is inserted liquid level, upwards firmly pushes up piston handle with thumb, upwardly hollow piston rod, observe the liquid level of pipet, it is possible to judge the volume of imbitition in advance according to position on graduation mark, hollow piston rod-5 bottom simultaneously.During tapping: when needing the liquid inside pipet all to flow out, available thumb opens rod gland, and liquid flows out naturally；Also with being not switched on rod gland, piston handle can be pushed down on thumb, observe pipet liquid level scale simultaneously, release quantitative liquid.
This utility model is rational in infrastructure, processing ease, it is achieved that what one hand completed reagent pipettes work, and the speed pipetted is easily controlled, it is to avoid the waste of reagent and the injury to personnel, can mate use with the pipet of different size, and cost is low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, this utility model being further described, Fig. 1 is perspective view of the present utility model.
Detailed description of the invention
One and the matching used pipettor of pipet, as shown in Figure 1, including the cone barrel pipet interface 1 being provided with rubber internal layer 2, the lower surface of piston cylinder 3 arranges the connector matched with pipet interface 1, coordinate in piston cylinder 3 and hollow piston rod 5 is installed, the lower end of hollow piston rod 5 is uncovered, upper end arranges the piston handle 6 closed, sidepiece at piston handle 6 arranges the control pipe 7 connected with hollow piston rod 5, the outer end controlling pipe 7 is closed, and is installed with sealing lid 8 or hand-operated valve controlling to coordinate on the through hole that pipe 7 is arranged.Uniform on piston cylinder 3 metering scale 4 is set.
Claims (2)
1. one kind and the matching used pipettor of pipet, including cone barrel pipet interface (1) being provided with rubber internal layer (2), it is characterized in that: the connector matched with pipet interface (1) is set on the lower surface of piston cylinder (3), coordinate in piston cylinder (3) and hollow piston rod (5) is installed, the lower end of hollow piston rod (5) is uncovered, upper end arranges the piston handle (6) closed, sidepiece at piston handle (6) arranges the control pipe (7) connected with hollow piston rod (5), the outer end controlling pipe (7) is closed, controlling the through hole that pipe (7) is arranged coordinates, sealing lid (8) or hand-operated valve are installed.
2. one according to claim 1 and the matching used pipettor of pipet, is characterized in that: uniform arrange metering scale (4) piston cylinder (3) is upper.
