Background technology
Pipette is that one kind measuring formula instrument, only is used for measuring the volume of its released solution, it is an elongated glass
Glass pipe, lower end are sharp mouth shape, a graticule are carved at the caliber of upper end, expression pipettes to obtain exact volume；Current chemistry examination
Substantially several steps of pipette application method in agent, are washed with distilled water pipette for several times, are moistened with the sample of liquid first
It washes three times；When pipetting solution, the tip of pipette is goed deep into solution, left hand takes ear washing bulb, the right hand to hold on pipette graticule
It removes ear washing bulb rapidly when liquid level rises to required scale or more with ear washing bulb in solution sucking pipette, uses in side
Right finger blocks liquid relief nozzle, and index finger is loosened in then pico- rotation, and liquid level is allowed slowly, smoothly to decline, recessed until solution
Liquid level drops to required scale and is on a horizontal surface, and and then presses tight nozzle, does not allow solution to flow out；Finally by the point of pipette
End leans against on the inner wall of receiving device, allows solution freely to flow out, when solution being waited no longer to flow out, pipette is taken away.It takes at this
During liquid, if carry out imbibition cannot be stablized when imbibition, horizontal plane can be caused unhorizontal, and if ear washing bulb take away finger
It is not rapid enough when blocking, drawn solution can be caused to decline too fast, required scale or less may be dropped to；It is being put
When liquid, the operation that finger is loosened in pico- rotation is possible to that liquid level can be caused to drop to required scale hereinafter, bad control
Liquid discharge amount processed not can determine that accurate liquid relief amount, cumbersome, and increase the probability of experimental error.
Invention content
The purpose of this utility model provides a kind of new chemical experiment in order to solve the above-mentioned problems of the prior art
With micro control pipette.
To achieve the goals above, the utility model provides following technical solution：A kind of experiment of new chemical is with micro
Pipette is controlled, including pipette main pipe, adjustable support, micro control syringe, ear washing bulb, the adjustable support have
Up and down adjustment axis and left and right adjusting axis can be adapted for the different containers for taking liquid and carry out imbibition, it is ensured that pipette can be stablized
Imbibition is carried out, keeps operation easier；Pipette main pipe's top open part has cock, upper right opening also to have rotation
Plug, it is ensured that the seal during pipette use also can preferably carry out imbibition and drain operation, in the master of pipette
Tube body is marked with scale, and the amount of liquid in pipette can be read；There is scale on the micro control syringe, with pipette master
Tube body has certain proportion relationship, liquid extra in pipette can be discharged by the air being discharged in micro control syringe
Body can control the accuracy of liquid relief amount.
Further, the micro control pipette is mainly made of pipette main pipe and micro control syringe, is passed through
Master cock and sidespin plug form closed pipette, can carry out imbibition and control liquid relief amount respectively by rotating cock, and
It can guarantee the seal of pipette in the operation of imbibition and drain, increase the accuracy of liquid relief amount, reduce the error in operation.
Further, the scale of the scale of the pipette main pipe and micro control syringe has certain proportionate relationship,
The gas volume of five down scales of micro control syringe can allow liquid in pipette main pipe to decline one in pipette
Down scale can more accurately control the liquid relief amount of needs.
Further, the adjustable support can carry out liquid relief in varied situations, can carry out up and down adjustment, can also carry out
Left and right adjusting can be useful in different vessels and carry out imbibition, ensure that easy progress is more stablized in imbibition.
Further, two openings of main pipe have cock, can be adjusted, and master cock can be in ear washing bulb imbibition
Later then rotation passes through micro control to ensure that the seal of pipette, sidespin plug can be opened in the imbibition amount of being drawn through
Extra solution is discharged in syringe.
Further, entire micro control pipette is all made by polytetrafluoroethylene material.
