Description
Technical field
The present invention relates to a kind of chemical experiment apparatus, specially a kind of two-chamber injecting type pipette.
Background technology
What is be used in conjunction with pipette in current biochemical test is ear washing bulb, and solution is sucked into pipette by extruding ear washing bulb
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
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 replace ear washing bulb with syringe, but in operation, because syringe range is considerably beyond liquid relief
The need for pipe, so the liquid level being difficult in precise control pipette.
The content of the invention
The purpose of the present invention, is to provide a kind of two-chamber injecting type pipette, is substituted using the dual chamber syringe transformed and washed
Ear ball is used cooperatively with pipette, can accurately by solution suction pipette and regulating liquid surface highly.
In order to solve the above-mentioned technical problem, the present invention is achieved through the following technical solutions：A kind of two-chamber injecting type pipette,
Including pipette and dual chamber syringe.The dual chamber syringe is the injection-tube that a cross section is annular, is provided with thick in injection-tube
Plunger shaft and small piston chamber；The extra heavy pipe pull bar that extra heavy pipe piston is connected with extra heavy pipe piston is provided with thick plunger shaft；In small piston chamber
It is provided with the tubule pull bar that tubule piston is connected with tubule piston；One annular disk of injection-tube top covering, extra heavy pipe pull bar and thin
Pipe pull bar is passed from annular disk respectively, and extra heavy pipe pull bar top is provided with extra heavy pipe drawing handle for push-and-pull extra heavy pipe piston, tubule
Pull bar top is provided with tubule drawing handle for push-and-pull tubule piston.The dual chamber syringe bottom is provided with connection pipette
Syringe composite anti-blocking.The volume of the dual chamber syringe is more than pipette volume；Liquid relief pipe surface is provided with the quarter of mark liquid measure
Degree line.
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 the detachable nested encryptions of sealing of pipette and dual chamber syringe.
During using the present invention, first pipette is tightly connected with dual chamber syringe, then moves extra heavy pipe piston and control roughly
Liquor capacity in pipette, moves tubule piston afterwards, and solution is taken come precise control according to the graduation mark on pipette
Volume.Be not in that required liquid sucks excessive or very few situation in experimentation by the method.
Simple to operate, convenient use of the invention, improves pipette and takes the efficiency and accuracy of liquid, so as to improve biochemical real
The accuracy tested, while liquid can be controlled accurately, it is ensured that the safety of experimenter.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings：
Fig. 1 is composition schematic diagram of the invention.
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, 4- dual chamber syringes, 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-pull hands
Handle, 45- tubule drawing handles, 46- annular disks, 47- tubule pull bars, 48- tubule pistons, 49- small pistons chamber.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, dual chamber syringe 4 is the injection-tube that a cross section is annular, thick plunger shaft 41 is provided with injection-tube
With small piston chamber 49.The extra heavy pipe pull bar 43 that extra heavy pipe piston 42 is connected with extra heavy pipe piston 42 is provided with thick plunger shaft 41；Small piston
The tubule pull bar 47 that tubule piston 48 is connected with tubule piston 48 is provided with chamber 49；Injection-tube top covering annular disk 46, slightly
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
For push-and-pull extra heavy pipe piston 42, the top of tubule pull bar 47 is provided with tubule drawing handle 45 for push-and-pull tubule piston 48.
The bottom of dual chamber syringe 4 is provided with the syringe composite anti-blocking 3 of connection pipette 1, and syringe composite anti-blocking 3 includes note
Emitter 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 it is identical, its external diameter is identical with the internal diameter of syringe outer rim bayonet socket 31.The top of pipette 1 is set on syringe entrance 32
And fixed by syringe outer rim bayonet socket 31, reach the detachable nested encryptions of sealing of pipette 1 and dual chamber syringe 4.Two-chamber is noted
More than the volume of pipette 1, the surface of pipette 1 is provided with the graduation mark 2 of mark liquid measure to the volume of emitter 4.
When drawing liquid to pipette 1, after being first tightly connected pipette 1 and dual chamber syringe 4, pull with hand extra heavy pipe and push away
Pull bar 43 is moved it up, and the negative pressure produced using dual chamber syringe 4 makes solution enter in pipette 1.When in pipette 1

Bar 43, stops mobile extra heavy pipe pull bar 43 when 1 to 2 centimetre of the corresponding scale of required liquid volume on liquid level distance scale line 2,
Tubule pull bar 47 is pulled again, according to the precise control liquid level of graduation mark 2, reaches necessary requirement.To other containers
During middle tapping, promote dual chamber syringe 4 in extra heavy pipe pull bar 43 and tubule pull bar 47, or by dual chamber syringe 4 with
Pipette 1 separates to reach the purpose of tapping.
Pipette 1 can be fabricated to various ranges, preferably 10ml, 25ml, 30ml range.
