Abstract
The utility model provides a pipette comprising a main pipe with scales. The pipette is characterized in that a side pipe with a one-way valve is arranged on one side of the main pipe, and a rubber hose with a glass ball inside is arranged on the main pipe. Since negative pressure can be formed conveniently in the main pipe through a rubber pipette bulb, liquid can be sucked into the main pipe, then under the function of the one-way valve which allows only air discharge but not air charge, the liquid in the main pipe can not automatically flow out of the pipe mouth, and simultaneously pollution to the rubber pipette bulb and the liquid due to the backflow of the liquid in the pipe can also be avoided; and in addition, the rubber hose arranged on the main pipe can be extruded to generate a gap between the rubber hose and the glass ball and to enable air to go into and out of the main pipe via the gap, so as to make micro adjustment to the liquid in the main pipe and accurately control the intake and the outflow of the liquid.
Description
Technical field
The utility model relates to a kind of pipette, and particularly a kind of liquid pipette belongs to scientific research assay technique field.
Technical background
At present, the pipette of experiment usefulness all is the glass tube of up/down perforation mostly, insert mouth of pipe imbitition by rubber pipette bulb during use, when the intraluminal fluid scale of construction is enough, remove rubber pipette bulb and block the glass mouth of pipe with finger, moveable finger or rotation glass tube slowly reduce liquid level to the position that needs, and move in the container that needs to add again.In this process, get liquid measure and be not easy control, move away to finger when blocking at rubber pipette bulb, liquid descends and causes quantity not sufficient rapidly easily, and the mode that adopts moveable finger or rotate glass tube is regulated too much liquid, also is difficult to control, needs skillfully operate.And get hypervolia, make liquid suck the pollution that rubber pipette bulb causes rubber pipette bulb and liquid easily.
Summary of the invention
Have the uncontrollable liquid turnover of pipette amount now for solving, and the problem that wastes time and energy, the utility model provides a kind of pipette.
The utility model is finished by following technical proposal: a kind of pipette, the person in charge who comprises band scale on it, it is characterized in that being responsible for the side pipe that a side is provided with band check valve in it, the person in charge is provided with the rubber hose of glaze ball in it, so that by placing the rubber pipette bulb on the side pipe port that liquid is sucked the person in charge, again by the extruding rubber hose, allow and produce the slit between rubber hose and the glass marble, make air through slit place into and out of, thereby the liquid in being responsible for is carried out trace adjustment, with accurate control liquid soakage.
Described side pipe is located at and is responsible for top, be provided with the check valve of outside unlatching in it, the side pipe port is connected with commercial rubber pipette bulb, so that when the rubber pipette bulb imbitition, make the unidirectional outflow of air in being responsible for, and after liquid is filled, when taking off rubber pipette bulb, ambient atmosphere then can't enter the person in charge, thereby the liquid that can not in being responsible for flows out automatically.
Described person in charge lower end is made as sharp-crested, and the upper end is made as flat mouthful, so that socket-connect with the flexible pipe of being with glass marble.
Described glass marble diameter is greater than the diameter of rubber hose, so as to make glass marble can and rubber hose combine closely, and air tight.
The utlity model has following advantage and effect: adopt such scheme, can be easily by rubber pipette bulb make form in being responsible for negative pressure and with liquid suck be responsible in, afterwards under the effect of the check valve that can not air inlet of can only giving vent to anger, liquid that can not in being responsible for is flowed out automatically from the mouth of pipe, thereby can move the person in charge easily, also avoided simultaneously liquid in pipe to flow backwards and to the pollution of rubber pipette bulb and liquid itself, in addition, can be responsible for by extruding and go up the rubber hose that is provided with, between rubber hose and glass marble, to produce the slit, allow air advance through the slit, go out to be responsible for, thereby the liquid in being responsible for is carried out trace adjustment, with accurate control liquid soakage and liquid outflow amount.Be a desirable liquid transporting device in fact.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further, is not limited thereto but hold within the utility model.
As Fig. 1, the pipette that the utility model provides, the person in charge 1 who comprises band scale 2 on it, a side of being responsible for 1 top is provided with the side pipe 7 of band check valve 8 in it, side pipe 7 ports 6 link to each other with commercial rubber pipette bulb, are responsible on 1 and are socketed with the rubber hose 3 of establishing glass marble 4 in it, are responsible for 1 lower end 9 and are made as sharp-crested, upper end 5 is made as flat mouthful, and glass marble 4 diameters are greater than the diameter of rubber hose 3.
Claims (4)
