Description
Technical field
The utility model is related to imbibition instrument more particularly to a kind of automatic pipettes of intelligence.
Background technology
Pipette is to be widely used in the instrument for drawing micro liquid of biology, chemical laboratory.Current liquid absorption device
Mainly using liquid-transfering gun, button, volume display window, sleeve, elastic suction nozzle, suction nozzle are shirked including control button, suction nozzle.Manually move
Liquid rifle mainly has to be loaded and the just mobile sample-adding two types of the piston using no mattress using mattress.Wherein use mattress
Sample injector can be conveniently used with the sample-adding of artificial fixation or adjustable volume liquid, and the scope of injection volume is less than 1ul extremely
Between l0ml.The effect of sample injector hollow air cushion is will to inhale to separate in the piston in the liquid sample and sample injector in plastic tips
It comes, mattress moves to move by the spring-like of sample injector piston, and then drives the liquid in suction nozzle, and disposable tip is
One important component of this sample adding system, shape, material property and with the degree of agreement of sample injector to the standard of sample-adding
Exactness has a great impact.It is loaded using just being moved with piston for no mattress for the sample injector and distributor of principle with mattress
The influence of physical factor suffered by device is different, and therefore, in the case where mattress sample injector is difficult to apply, piston just moves sample injector
It can apply, in the measure of such as with high-vapor-pressure, high stickiness liquid, to prevent the generation of aerosol, it is preferred to use living
The positive mobile sample injector of plug.Piston just moving sample injector suction nozzle and mattress sample injector suction nozzle it is different, including one can
The piston coupled with the piston of sample injector, the producer that this suction nozzle is generally just being moved sample injector by production piston forms a complete production network, no
The suction nozzle of common suction nozzle or different manufacturers can be used.More than liquid absorption device whole process needs manual operation, it is impossible to automatic fixed
Amount control volume, imbibition precision have much room for improvement.
The content of the invention
Purpose of utility model：The automatic pipette of intelligence provided by the utility model reduces manual operation, improves imbibition
Imbibition quality is also improved while speed.
Technical solution：The automatic pipette of intelligence provided by the utility model is inhaled including the first suction pipe, conical flask, second
Pipe, draught fan impeller, motor, the 3rd suction pipe, filter, first suction pipe one end are fixed on above EP pipes, other end insertion taper
In bottle；Motor is connected with draught fan impeller；In second suction pipe one end insertion conical flask, the other end is connected with draught fan impeller；It crosses
Filter disc is embedded in the second suction pipe；3rd suction pipe is inserted vertically into conical flask.
First suction pipe includes regulation device knob and the first imbibition nozzle positioned at its lower end, the second imbibition nozzle and the 3rd inhale
Liquid mouth；Imbibition nozzle includes adjusting range knob, range display device, installation pipette tips position；Installation pipette tips position can install the volley of rifle fire,
Filter is made of and replaceable sponge filter disc, and conical flask is managed when drawing micro liquid using EP.
Operation principle：The automatic pipette of the utility model intelligence makes air by the rotation of motor high-speed driving draught fan impeller
Discharge causes to generate instantaneous vacuum inside the automatic pipette of intelligence and external atmosphere pressure forms Negative Pressure Difference, in the effect of this pressure difference
Under, suck the liquid and air needed for containing experiment.Liquid and air by the first suction pipe through draught fan impeller and motor act on into
Enter in conical flask, wherein liquid is left in conical flask, and air is after the filter in the second suction pipe by motor using being discharged,
This layer of filter is one of protective barrier for preventing the sucking such as liquid or solid motor after taper bottle breakage.
Advantageous effect：Compared with prior art, the automatic pipette of the utility model intelligence uses draught fan impeller and motor
Driving, reduces manual operation, and then ensures the accuracy of experiment；It can in high volume quick imbibition, and more according to liquid
Range is selected less, and imbibition quality is also improved while rate of liquid aspiration is improved；Instrument will not be damaged due to no to scale,
It will not be because being inverted pipette tips damage instrument.
