Abstract
The utility model relates to a pipette and belongs to the technical field of chemical laboratory apparatuses. The defects of small aperture and easy air leakage in the butt joint with an ear washing bulb of the 1 ML and 2 ML pipettes in the prior art are overcome. The pipette mainly comprises a pipette tip and a pipette body with scales, wherein the pipette tip is arranged on the bottom part of the pipette body; and an inverted conical interface with a height of 0.5-1cm is arranged on the top end of the pipette tip. The pipette provided by the utility model is mainly applied in 1 ML or 2 ML chemical pipetting experiments.
Description
Technical field
The utility model relates to a kind of pipette, and it belongs to the chemical experimental instrument technical field.
Background technology
Pipette is the measuring device that accurately pipettes the solution of certain volume.Pipette is a kind of formula instrument that measures, and only is used for measuring the volume of its solution of emitting.In the experiment of some quantitative analyses, the pipette of 1ML and 2ML must be used, and in the quantitative analysis such as protein, need to add 40% the NaOH of 1 ~ 2ML, must with the pipette of 1ML or 2ML, can reduce error like this.Yet the pipette of 1ML and 2ML is due to suitable little of internal diameter, the bore position is also very small, has caused the tip of ear washing bulb to be not easy to insert, and an inclination will cause the gas leakage of ear washing bulb a little, make solution inhale and do not enter, artificial prolongation the time of experiment, cause the appearance than multiple error.
The utility model content
The utility model is little for the pipette bore of 1ML in prior art and 2ML, deficiency that easily leak gas when docking with ear washing bulb, and a kind of more airtight pipette that is connected with ear washing bulb is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows:
A kind of pipette comprises body and tip, and described tip is located at the bottom of body; Described body top is provided with the interface of back taper.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the height of described interface is 0.5 ~ 1cm; The wall of described body is provided with scale.
Compared with prior art, the beneficial effects of the utility model are: interface is changed into the structure of back taper, can easily ear washing bulb be inserted its inside, thereby make it more airtight with being connected of ear washing bulb, well avoid the generation of gas leak phenomenon, thereby reduced the error of experiment; Simple in structure, easy to operate, shortened the time of testing.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Interface in the drawings, 1; 2, body; 3, scale; 4, tip.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
A kind of pipette comprises tip 4 and with the body 2 of scale 3, described tip 4 is located at the bottom of body 2; It is highly interface 1 0.5 ~ 1cm, back taper that described body 2 tops are provided with.
the utility model in use, right-handed thumb and middle finger pinch the body 2 of pipette, tip 4 is inserted in solution to be drawn, left hand is taken ear washing bulb, insert interface 1 and keep airtight, solution is slowly sucked body 2, when rising to body 1/2nd three height, takes out solution, horizontal holding, and rotation body 2, make solution evenly be covered with whole body 2 inwalls, with displacement inwall moisture, the solution of avoiding the interior remaining moisture dilution of body 2 to remove produces unnecessary error, then solution is discarded to waste fluid container from tip 4, above-mentioned replacement process repeats twice or thrice.After displacement, get final product draw solution to more than scale, right hand forefinger is pinned interface 1, body 2 is shifted out solution container to be got, tip 4 is leaned against on a clean container inner wall, body 2 is kept upright, slightly loosen forefinger, shift out after dropping liquids in body 2 are removed by wall.Body 2 is put into the container of accepting solution, make tip 4 against container inner wall, container slightly tilts, and 2 of bodys keep vertical, decontrol forefinger, solution is flowed down naturally along container inner wall, after flow of solution in body 2 is clean, then wait for 15 seconds, take out body 2, a small amount of liquid of staying tip 4 does not blow out, and keeps the volume of solution because the sign volume of body 2 has been considered tip 4.
The above is only preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
