Abstract
The utility model proposes a kind of pipette, the problem that when solving the liquid that in prior art, pipette, extract viscosity is larger, suction force is poor, a kind of pipette, comprises pipette body, and the top of described pipette body is provided with main suction pipe and secondary suction pipe; The equal movable sleeve of end of described main suction pipe and described secondary suction pipe is connected to air bag; Described pipette body and described main suction pipe, described secondary suction pipe form Y-shaped threeway tubing string, and the angle between described main suction pipe and described secondary suction pipe is 30 °; Described secondary suction pipe is provided with switch near described pipette body place, pipette body is furnished with two air bags, when the liquid that absorption viscosity is larger, only need extrude two air bags just can be drawn to required amount simultaneously, simple to operate.
Description
Technical field
The utility model relates to chemical apparatuses field, refers to a kind of pipette especially.
Background technology
Pipette is that use for laboratory is in a kind of solution of absorption to the utensil in another container.General pipette, extract liquid adapted ear washing bulb often, that is ear washing bulb is other adapted, when the liquid that absorption viscosity is larger, an independent ear washing bulb is used to be difficult to the liquid assimilating of thickness to required dosage, suction force is poor, obtain repeatedly to draw and just can reach required amount, bring inconvenience to experimentation.
Utility model content
The utility model proposes a kind of pipette, the problem that when solving the liquid that in prior art, pipette, extract viscosity is larger, suction force is poor.
The technical solution of the utility model is achieved in that a kind of pipette, comprises pipette body, and the top of described pipette body is provided with main suction pipe and secondary suction pipe; The equal movable sleeve of end of described main suction pipe and described secondary suction pipe is connected to air bag; Described pipette body and described main suction pipe, described secondary suction pipe form Y-shaped threeway tubing string, and the angle between described main suction pipe and described secondary suction pipe is 30 °; Described secondary suction pipe is provided with switch near described pipette body place.
As preferred technical scheme, described pipette body is marked with scale.
As preferred technical scheme, the end of described main suction pipe is provided with spherical hollow space.
As preferred technical scheme, described spherical hollow space radius be greater than the radius of described main suction pipe.
The utility model compares produced beneficial effect with background technology:
Pipette body is furnished with two air bags, when the liquid that absorption viscosity is larger, only need extrude two air bags just can be drawn to required amount simultaneously, simple to operate, when drawing the less liquid of viscosity, can closing switch, draw with main gasbag and just can, flexible operating, and the spherical hollow space be provided with on main suction pipe, for anti-suck.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is a kind of pipette structural representation of the utility model.
In figure: 1-pipette body; The main suction pipe of 2-; 3-spherical hollow space; 4-air bag; The secondary suction pipe of 5-; 6-switch.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of pipette, comprises pipette body 1, and pipette body 1 is marked with scale, and the top of pipette body 1 is provided with main suction pipe 2 and secondary suction pipe 5; The equal movable sleeve of end of main suction pipe 2 and secondary suction pipe 5 is connected to air bag 4, and two air bag 4 cavity volume are equally large; Pipette body 1 and main suction pipe 2, secondary suction pipe 5 form Y-shaped threeway tubing string, and the angle between main suction pipe 2 and secondary suction pipe 5 is 30 °; Secondary suction pipe 5 is provided with switch 6 near pipette body 1 place, and when the liquid that absorption viscosity is larger, switch 6 of outwarding winding, extrudes two air bags 4 simultaneously, and when the liquid that absorption viscosity is larger, screw switch 6, secondary suction pipe 5 does not work.The end of main suction pipe 2 is provided with spherical hollow space 3, spherical hollow space 3 radius be greater than the radius of main suction pipe 2, spherical hollow space 3 is for guarding against in liquid suck-back air bag 4.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
