It is interior, after taking liquid to complete using 1 accurate quantification imbibitions of liquid-transfering gun, the negative pressure in the piston cavity of 1 gun body 12 of liquid-transfering gun
Event resolves are arranged and are adsorbed again between the magnetic floating valve 62 and magnet ring of tapered channel 611, to consolidate ball valve 62
Ground is adsorbed on the position of 611 liquid outlet of tapered channel in one-way fluid channel 61, with real by the cooperation of ball valve 62 and magnet ring 53
Existing measuring pipet 5 unidirectionally opens its taper suction inlet 52 so that the extractant liquid drawn in measuring pipet 5 will not be because of under gravity
It drops and flows out measuring pipet 5, on the one hand can reach liquid relief fast and accurately effect.
4) when needing to pipette the extractant of large capacity, above-mentioned steps 1 only need to be repeated in), 2) and 3) operation, negative pressure
Extractant in sucking 5 amount sap cavity 51 of measuring pipet will flow into the installation for the different size being connect with liquid storage cylinder 7 by liquid storage cylinder 7
In big volume quantitative liquid storage bottle 8, to realize that control takes the capacity of liquid, under the control of liquid-transfering gun 1, large capacity is disposably measured
Extractant, improve the stability that measuring pipet measures extractant operation, operation that is convenient, simplifying pipette ensure that primary
Property take liquid success.
The foregoing is merely the better embodiments of the present invention, and the invention is not limited in the above embodiments, are implementing
There may be the small structural modifications in part in the process, if the various changes or modifications of the present invention are not departed from the essence of the present invention
God and range, and belong within the scope of the claim and equivalent technologies of the present invention, then the present invention is also intended to comprising these changes
And modification.
