Shape suction inlet 52 is inserted into the liquid level of extractant to be pipetted hereinafter, opening the switch valve 3 on the first suction pipe 3, and the right hand is by syringe 1
Push-pull rod 13 pulls up, and the intraluminal piston 12 of driving injection-tube 11 moves upwards, to be produced in the tube chamber of injection-tube 11
Under raw suction function, extractant to be pipetted enters the taper suction inlet 52 of measuring pipet 5, and overcomes and be arranged in the first tapered channel
Adsorption capacity between 611 magnetism the first float valve 62 and the first magnet ring 53 and float valve 62 is gone out into liquid from the first tapered channel 611
Mouth is open-top so that the first tapered channel 611, which is opened, to be simultaneously connected with the liquid storage cylinder of measuring pipet 5 51.In the tube chamber of injection-tube 11
Suction function under, extractant to be pipetted will be constantly inhaled into the liquid storage cylinder 51 of measuring pipet 5, when the liquid storage of measuring pipet 5
When being full of extractant in chamber 51, the extractant in liquid storage cylinder 51 will pass sequentially through the top end opening of liquid storage cylinder 51, floating ball pallet
Through flow hole 731 on 73 enters in the second one-way fluid channel 71, and the second ball valve 72 being arranged on floating ball pallet 73 is in buoyancy
Under the action of move upwards, and under the magnetic attraction force effect of the second magnet ring 54 so that the second ball valve 72 be located at the second taper lead to
The most significant end in road 711 can block the second tapered channel 711, to effectively prevent the piston 12 due to syringe 1 to push and pull
Fast and easy imbibition is too quickly, and extractant is immediately wicked into the injection-tube 11 of syringe 1 from the top ports of pipette.Meanwhile by
It is closed in the second one-way fluid channel 71, the intraluminal suction function of injection-tube 11 disappears, and is arranged in the first tapered channel
It is attracted again between 611 magnetism the first float valve 62 and the first magnet ring 53, it is single first to firmly inhale the first ball valve 62
To the position of 611 liquid outlet of the first tapered channel of fluid channel 61, to pass through the cooperation of the first ball valve 62 and the first magnet ring 53
Realize that 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 gravity
Decline and flow out measuring pipet 5, to reach liquid relief fast and accurately effect.When the extractant excess in measuring pipet 5, only need to close
The switch valve 3 on the first suction pipe 3 is closed, the first magnet ring 53 and the second magnet ring 54 on 5 lateral wall of pico- mobile measuring pipet, make respectively
The 72 equal sky of the second float valve of the first float valve 62 and the second tapered channel 711 that obtain the first tapered channel 611 is stayed can with tiny
For the gap of extractant circulation, then squeeze the emulsion tube 42 in 41 left side of glass marble so that shape between emulsion tube 42 and glass marble 41
It is in communication with the outside at a narrow gap so that ambient atmos enter in the measuring pipet 5 of pipette, adjust the extraction in measuring pipet 5
It takes agent liquid level to drop to designated position, the first float valve 62 is then moved away from by going out for the first tapered channel 611 by the first magnet ring 53
Liquid mouth position pushes the drawing handle 14 of syringe 1 still further below, to quantify tube chamber of the extractant pipetted from injection-tube 11
Tapping in introversive other containers, to realize that accurate quantification takes the purpose of liquid.
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.
