Abstract
The utility model discloses a pipette, which comprises a tube body with a scale, wherein a side pipe with a one-way valve inside is arranged at one side of the pipe body, and a cock is arranged on the pipe body, and a vent through hole is arranged on the cock. The pipette provided by the utility model is convenient to operate and easily controls the amount of the taken liquid.
Description
Technical field
The utility model relates to a kind of pipette, relates in particular to a kind of liquid pipette, belongs to scientific research chemical examination field.
Background technology
At present; Mostly the pipette that experiment or check are used is the straight shape glass tube of up/down perforation; Insert mouth of pipe imbitition by inhaling ball during use, when the intraluminal fluid scale of construction is enough, takes away the suction ball and block the mouth of pipe with finger; Moveable finger slowly reduces liquid level to the amount that needs, and moves in the vessel that will 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 ear ball and liquid easily.
Summary of the invention
The purpose of the utility model provide a kind of easy to operate, get the easily pipette of control of liquid measure, effectively overcome above-mentioned deficiency.
The technical scheme that is adopted is:
A kind of pipette comprises the body of being with scale on it, and body one side is provided with the side pipe of band check valve in it, and cock is housed on the body, has ventilative through hole in the cock.
After adopting such scheme, during use, utilize rubber pipette bulb to push absorption at the side pipe mouth of pipe; Make to form negative pressure in the body and liquid is sucked in the body, afterwards can only give vent to anger can not the check valve effect of air inlet under, the liquid that can not in the body is flowed out from the side pipe mouth of pipe automatically; Thereby can move body easily, also avoid simultaneously liquid in pipe to flow backwards and to the pollution of rubber pipette bulb and liquid itself, in addition; Can be through ventilative through hole in the cock; The Spin Control micro-air flows into body, thereby the liquid in the body is carried out the trace adjustment, with accurate control liquid soakage and liquid outflow amount.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of the utility model cock.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done further elaboration.
A kind of pipette as shown in Figure 1 comprises the body 1 of being with scale on it, and a side on body 1 top is provided with the side pipe 2 of band check valve 3 in it, and side pipe 2 mouths of pipe are used for linking to each other with commercial rubber pipette bulb; Body is provided with column type tubular body 4, and with a cock 5 close fit, cock 5 is provided with through hole as shown in Figure 26; The diameter of through hole 6 is less than the diameter of body 1; Contact-making surface between cock 5 and the column type tubular body 4 needs to handle through polishing, can guarantee its sealing like this, during use; Smooth for guaranteeing cock, can be coated with the vaseline of last layer lubricate at the ground place.
