Abstract
The utility model discloses a transfer pipette provided with a bulb and pores and allowing for accurate discharge control, and belongs to the technical field of general test instruments. The bulb fixedly or movably connected with an upper opening of the transfer pipette is disposed on the upper opening of the transfer pipette, and from one to three pores are reserved on one side of a small straight tube located below the upper opening of the transfer pipette. When one pore is provided, the pore can be located at a first pore position, a second pore position and a third pore position. When two pores are provided, the pores can be located at the first pore position and the second pore position, or the second pore position and the third pore position, or the first pore position and the third pore position. When three pores are provided, the pores are located at the first pore position, the second pore position and the third pore position respectively. The transfer pipette is reasonable in design, simple in structure and convenient to use, high volume accuracy of liquid to be transferred can be guaranteed, and accurate experimental and testing results can be obtained better.
Description
Technical field
The utility model belongs to test tool technical field commonly used, is specifically related to the novel pipette that a kind of band that can accurately control the fluid discharge amount is inhaled ball and micropore.
Background technology
During existing pipette pipetting, use earlier the ear washing bulb imbibition, push down mouth of pipe upper end with finger again and control air inflow, bleed off, make the required dosage of its arrival being drawn into chemical solvent unnecessary in the pipette.Because the mouth of pipe is thicker, can't accurately control mass rate of emission during finger presses, the discharge capacity error is bigger.Excessive when air inflow, discharge when too much, the dosage of pipette internal solvent causes heavily and inhales below required graduation mark.When air inflow too small, discharging hour, the dosage that causes the pipette internal solvent more than required graduation mark, cause measure inaccurate.
The utility model content
Above-mentioned deficiency to prior art; The technical problem that the utility model will solve provides a kind of with the pipette that can accurately control discharge capacity of inhaling ball and micropore; It is easy to operate, is easy to control the discharge capacity of unnecessary liquid in the pipette, make testing sample liquid to move the liquid measure degree of accuracy high.
The technical scheme of the utility model is: a kind of upper orifice setting with the pipette that can accurately control discharge capacity of inhaling ball and micropore is fixedly connected with it or the suction ball of flexible connection, and a side of the little straight tube under the upper orifice of said pipette is provided with one to three micropore.Described micropore is set to one, and its position is the first micropore position or the second micropore position or the 3rd micropore position.Described micropore is set to two, and its position is the first micropore position and the second micropore position, or the second micropore position and the 3rd micropore position, or the first micropore position and the 3rd micropore position.Described micropore is set to three, and its position is the first micropore position, the second micropore position and the 3rd micropore position.
The micropore size of the said first micropore position, the second micropore position and the 3rd micropore position is 0.5mm～2.5mm.The distance of the said first micropore distance of positions upper orifice is 4cm～6cm.Spacing between adjacent two holes of the said first micropore position, the second micropore position and the 3rd micropore position is 1.5cm～4cm.
The utility model is reasonable in design, and is simple in structure, easy to use, can guarantee to pipette the volume accuracy height of liquid, can obtain the accurate result of test and test job better.
Description of drawings
Accompanying drawing 1 is the utility model one example structure sketch map;
Accompanying drawing 2 is another example structure sketch mapes of the utility model.
The accompanying drawing acceptance of the bid is kept the score and is stated as follows: 1-pipette; 2-suction ball; 3-the first micropore position; 4-the second micropore position; 5-the three micropore position; 6-little straight tube; 7-graduation mark; 8-outlet.
The specific embodiment
Be described in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.Like accompanying drawing 1, shown in 2, when using the utility model, pin one to three micropore position with one or two or three finger, with inhaling ball 2 liquid is drawn in the pipette 1.After imbibition was accomplished, the amount of liquid in being drawn into pipette surpassed required graduation mark 7 when a lot, unclamp the first micropore position 3 that finger presses or/and the second micropore position 4 or/and the micropore of the 3rd micropore position 5; Let the air first micropore position 3 or/and the second micropore position 4 or/and the micropore of the 3rd micropore position 5 gets into, is managed interior air pressure and changed rapidly, liquid flows out through outlet 8 fast; When liquid in pipe during near the graduation mark 7 of required dosage, two fingers are pinned two micropores wherein, unclamp one of them micropore; Under the effect of air pressure, solvent slowly flows out, when the pipe internal solvent just arrives the graduation mark 7 of required dosage; Three fingers are pinned three micropores respectively; Guarantee that liquid that can not flows out, excess liquid will emit in the pipette 1 thereby will be drawn into fast and accurately, obtain metering liquid accurately.Shown that by accompanying drawing 1 upper orifice of inhaling ball 2 and pipette 1 is connected to one, accompanying drawing 2 shows, the upper orifice of inhaling ball 2 and pipette 1 is what to be flexibly connected to one, and the bottom of inhaling ball 2 is socketed in outside the upper orifice of pipette 1.The pipette of the utility model has easy to operate and is easy to control the characteristics of the discharge capacity of unnecessary solvent in the pipette, and the degree of accuracy that can guarantee to pipette solvent to be measured is high.
