Abstract
The utility model discloses an integration, pipette of steerable discharge, this kind of pipette is constituteed by washing ear ball, bleed valve, pipette, washes the ear ball and links to each other through connecting rubber tube and pipette, and the pipette is equipped with the bleed valve with washing between the ear ball, and the one end of bleed valve division has the inlet port, through the discharge of solution in the steerable pipette of degree of opening and shutting of adjusting the bleed valve. The utility model discloses a pipette has improved the stability that solution was got to the pipette volume, has realized the one -hand operation pipette volume of carrying on and has got solution.
Description
Technical field
The utility model relates to a kind of chemical experimental instrument, is mainly used in, in chemical experiment process, accurately pipetting chemical reagent.
Background technology
In chemical experiment process, often use liquid reagent, the use amount of reagent has strict requirement, usually adopts pipette to measure.The pipette used in chemical laboratory at present, generally all be made up of pipette and ear washing bulb two parts, in use, two hands are needed to coordinate, pipette suitable for reading aimed at the tip of ear washing bulb and is adjacent to, then extruding ear washing bulb, pipette being stretched in reagent bottle below liquid level of solution, slowly unclamp ear washing bulb, extract solution by the negative pressure in pipette.Measure in solution processes at use conventional pipette, the connection of ear washing bulb and pipette is by realizing by hand, and the connection of the two is unfixed, easily comes off, leak gas, affects carrying out smoothly of testing.
Summary of the invention
For solving the problem, the utility model provides a kind of integration, can facilitate the pipette of control flow check output, conventional pipette and ear washing bulb have been carried out integrated design by this pipette, and between pipette and ear washing bulb, devise the device of vent valve, the discharge of solution in pipette is controlled by the opening degree adjusting vent valve.
The technical scheme that the utility model technical solution problem adopts is: the utility model is made up of ear washing bulb, vent valve, pipette, and ear washing bulb lower end is connection rubber tube, and vent valve is equipped with on sebific duct top, and one end of vent valve has air admission hole.Ear washing bulb is connected with pipette by connection rubber tube, and sebific duct adopts elastic material.
The beneficial effects of the utility model are, the pipette of routine and ear washing bulb have been carried out integrated design by the utility model, controlled the discharge of solution in pipette by vent valve, improve the stability that pipette measures solution, achieve one-handed performance pipette and carry out measuring solution.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structure chart of the utility model embodiment;
Fig. 2 is the details enlarged diagram of part A in Fig. 1 the utility model example structure figure;
Wherein,
(1), ear washing bulb; (2), air admission hole; (3), connection rubber tube; (4), pipette; (5), vent valve.
Detailed description of the invention
In FIG, by the connection rubber tube (3) of ear washing bulb (1) and suitable for reading aligning of pipette (4), by the upper end precession connection rubber tube (3) of pipette (4), by ear washing bulb (1) and pipette (4) compact siro spinning technology.Screw vent valve (5) clockwise, squeeze ear washing bulb (1), the air in pipette (4) is discharged, then pipette (4) is stretched into reagent bottle, slowly unclamp ear washing bulb (1), measure solution by the negative pressure in pipette (4).
When needing to use the reagent in pipette (4), counterclockwise slow circumvolve vent valve (5), air is entered from air admission hole (2), and reagent will flow out from pipette.
Claims (2)
1. the pipette of controllable flow output, is made up of ear washing bulb, vent valve, pipette, it is characterized in that: ear washing bulb lower end is connection rubber tube, and ear washing bulb is connected with pipette by connection rubber tube, and vent valve is equipped with on sebific duct top, and one end of vent valve has air admission hole.
2. the pipette of controllable flow output according to claim 1, is characterized in that: connection rubber tube adopts elastic material.
