Description
Technical field
The utility model is related to a kind of chemical experiment apparatus, specially a kind of compound injecting type pipette.
Background technology
What is be used in conjunction in current biochemical test with pipette is ear washing bulb, and pipette is sucked by extruding ear washing bulb by solution
In, liquid level is regulated and controled by finger afterwards.Therefore the volume of suction liquid is relevant with manual operation, when the liquid level of solution is not up to
To when requiring, generally require to repeat, and easily because ear washing bulb extruding degree is excessive, cause solution to overflow and injure operation
Personnel.There is experimenter and ear washing bulb is replaced with syringe, but in operation, because syringe range is considerably beyond liquid relief
The need for pipe, so being difficult to the liquid level in accurate control pipette.
The content of the invention
The purpose of this utility model, is to provide a kind of compound injecting type pipette, utilizes the compound injection transformed
Device substitutes ear washing bulb and used cooperatively with pipette, solution accurately can be sucked into pipette and regulating liquid surface height.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：A kind of compound injecting type
Pipette, including pipette and compound syringe.The compound syringe is the injection-tube that a cross section is annular, injection
Thick plunger shaft and small piston chamber are provided with pipe；Heavy manual labour plug intracavitary is provided with extra heavy pipe piston, the extra heavy pipe pull bar being connected with extra heavy pipe piston；
Small piston intracavitary is provided with tubule piston, the tubule pull bar being connected with tubule piston；One annular disk of covering, extra heavy pipe at the top of injection-tube
Pull bar and tubule pull bar are passed from annular disk respectively, are used for push-and-pull extra heavy pipe provided with extra heavy pipe drawing handle at the top of extra heavy pipe pull bar
It is used for push-and-pull tubule piston provided with tubule drawing handle at the top of piston, tubule pull bar.The compound syringe bottom is provided with
Connect the syringe composite anti-blocking of pipette.The volume of the compound syringe is more than pipette volume；Liquid relief pipe surface is set
There is the graduation mark of mark liquid measure.
The syringe composite anti-blocking includes syringe outer rim bayonet socket and syringe entrance, and pipette tip is set in note
Fixed on emitter entrance and by syringe outer rim bayonet socket, reach pipette and the detachable nested company of the sealing of compound syringe
Connect.
During using the utility model, first pipette is tightly connected with compound syringe, extra heavy pipe piston is then moved thick
Liquor capacity slightly in control pipette, moves tubule piston, accurately controls to be taken according to the graduation mark on pipette afterwards
The volume of solution.Liquid sucks excessive or very few situation needed for being not in by the method, in experimentation.
The utility model is simple to operate, convenient use, efficiency and accuracy that pipette takes liquid is improved, so as to improve life
Change the accuracy of experiment, while liquid can be controlled accurately, it is ensured that the safety of experimenter.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is composition schematic diagram of the present utility model.
Fig. 2 is syringe composite anti-blocking Local map.
In figure：1- pipettes, 2- graduation marks, 3- syringe composite anti-blockings, 31- syringe outer rim bayonet sockets, 32- syringes enter
Mouthful, the compound syringes of 4-, 40- injection-tubes, the thick plunger shafts of 41-, 42- extra heavy pipes piston, 43- extra heavy pipe pull bars, 44- extra heavy pipe push-and-pulls

Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, it is that thick plunger shaft is provided with annular injection-tube, injection-tube that compound syringe 4, which is a cross section,
41 and small piston chamber 49.Provided with extra heavy pipe piston 42, the extra heavy pipe pull bar 43 being connected with extra heavy pipe piston 42 in thick plunger shaft 41；Fine work
Provided with tubule piston 48, the tubule pull bar 47 being connected with tubule piston 48 in plug chamber 49；Covering annular disk 46 at the top of injection-tube,
Extra heavy pipe pull bar 43 and tubule pull bar 47 are passed from annular disk 46 respectively, and the top of extra heavy pipe pull bar 43 is provided with extra heavy pipe drawing handle
44 are used for push-and-pull extra heavy pipe piston 42, and the top of tubule pull bar 47 is used for push-and-pull tubule piston 48 provided with tubule drawing handle 45.
Syringe composite anti-blocking 3 of the compound bottom of syringe 4 provided with connection pipette 1, syringe composite anti-blocking 3 includes
Syringe outer rim bayonet socket 31 and syringe entrance 32, as shown in Figure 2.The top end opening of pipette 1, its internal diameter and syringe entrance
32 external diameter is identical, and its external diameter is identical with the internal diameter of syringe outer rim bayonet socket 31.The top of pipette 1 is set in syringe entrance 32
Fixed above and by syringe outer rim bayonet socket 31, reach the detachable nested encryptions of sealing of pipette 1 and compound syringe 4.It is multiple
