Abstract
The utility model relates to a graduated pipette, which belongs to the technical field of experimental apparatus and overcomes the defects of the graduated pipette in the prior art that the liquid graduating volume is quantitative and the experimental operation is complicated. The graduated pipette comprises a pipe body, wherein a liquid storing pipe is arranged at the middle of the pipe body; a bearing bowl is arranged at the upper end of the pipe body; a sharp mouth is arranged at the lower end of the pipe body; and a glass ball is arranged in the bearing bowl and is externally connected with a rubber pipe; and graduation scales are evenly distributed on the outer surface of the pipe body. The graduated pipette is mainly used for chemical experiments.
Description
Technical field
The utility model relates to a kind of graduated pipette, and it belongs to experiment apparatus technical field.
Background technology
When laboratory is tested, the disposable pipette that will be often 5ml, 10ml, 25m, 50ml by specification pipettes solution, the volume difference pipetted, selected pipette is also different, and while measuring 15ml, 20ml equal-volume, also need two pipettes even three pipettes be used in conjunction with, bring inconvenience to experimentation, for example on the disposable pipette of 50ml, only has a graticule, what mean is that the volume size is 50ml, moving liquid must quantitatively, make experimental implementation more complicated at every turn.
The utility model content
The utility model moves liquid measure for the deficiency quantitative, that experimental implementation is more loaded down with trivial details for pipette in prior art, and a kind of graduated pipette is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of graduated pipette, comprise the middle body that is provided with liquid storage pipe, and described body upper end is provided with the load-bearing bowl, and lower end is provided with sharp mouth; Described load-bearing bowl inside is provided with glass marble, and is circumscribed with rubber tube; Described outer surface of tube body is evenly equipped with scale.
Compared with prior art, the beneficial effects of the utility model are: replace the disposable pipette of all size, the convenient use, avoided repeatedly using the trouble of pipette; And the automatic-sealed structure at top, make experimental implementation easier.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described body capacity is 50ml.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Rubber tube in the drawings, 1; 2, glass marble; 3, load-bearing bowl; 4, body; 5, liquid storage pipe; 6, scale; 7, Jian Zui.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
A kind of graduated pipette, comprise the middle body 4 that is provided with liquid storage pipe 5, and described body 4 upper ends are provided with load-bearing bowl 3, and lower end is provided with sharp mouth 7; Described load-bearing bowl 3 inside are provided with glass marble 2, and are circumscribed with rubber tube 1; Described body 4 outer surfaces are evenly equipped with scale 6.
The utility model is when making, and the capacity of described body 4 is 50ml.
The utility model in use, the suction nozzle of rubber pipette bulb is inserted in rubber tube, and when air-breathing, glass marble 2 suspends, and the solution in container enters in body 4 and reaches required scale 3 then, then take rubber pipette bulb away, glass marble 2 is interior by body 4 end sealings because the effect of gravity falls into load-bearing bowl 3; Pinch the rubber tube at glass marble 2 places with hand, make between rubber tube and glass marble and form space, according to required amount of moving liquid, adjust the scale 6 that the liquid in body 4 reaches, loose one's grip to complete and get liquid.
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 modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
