Abstract
The utility model discloses an adjustable quantitative pipettor for a laboratory, which relates to pipetting tools used in chemical, medical and health and biochemical fields and the like and comprises a liquor bottle, a plunger apparatus, a cylindrical scale and a pipette. The plunger apparatus is planted into the lower portion of the inside of the liquor bottle by the aid of a bottle cover of the liquor bottle, a sleeve of the plunger apparatus is fixed to the bottle cover, a liquid inlet is connected to the lower end of the sleeve, a liquid inlet one-way valve is disposed inside the liquid inlet, the pipette is communicated with the lateral wall of the sleeve, an output one-way valve is arranged in a pipeline, the pipette extends out of a body of the liquor bottle via the bottle cover and is L-shaped, a plunger is planted into the sleeve of the plunger apparatus from top to bottom and is in clearance fit with the sleeve, a push-pull handle is disposed at the top end of the plunger, a vernier is arranged on one side of the push-pull handle, and the vernier and the scale which is fixed onto the bottle cover are lapped with each other in a right-angle manner. The adjustable quantitative pipettor for a laboratory is reasonable in structural design, omits a spring, is additionally provided with the output one-way valve and the input one-way valve, and accordingly is simple, convenient and speedy in operation and more accurate in pipetting.
Description
Technical field
The utility model relates to fields uses such as chemistry, medical and health and biochemistry and moves the liquid instrument, particularly relates to a kind of laboratory adjustable quantitative pipettor.
Background technology
Pipettor is to utilize the straight line of its inner special piston in piston cylinder to move to change the piston cylinder internal capacity, thereby realizes the absorption or the discharge of liquid, reaches the purpose of quantitative transfer liquid.Pipettor suction amount of liquid is by the decision of piston cylinder amount of internal volume, and existing adjustable pipette is by adjusting device, changes the variation that the piston/cylinder volume is realized in piston rest point position on request, utilizes the effect of one-level spring force to make piston get back to initial position.In the adjusting device of a lot of existing pipettors, spring stress is in poor shape, cause its service life of having got rusty, having shortened spring, and it is inaccurate to move liquid.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of laboratory adjustable quantitative pipettor is provided.
Laboratory of the present utility model adjustable quantitative pipettor is to be made of solution bottle, plunger device, post chi and pipette.The plunger device is implanted the interior bottom of solution bottle by the bottle cap of solution bottle, the sleeve pipe and the bottle cap of plunger device fix, the lower end of sleeve pipe is connected with inlet, be provided with the feed liquor check valve in the inlet, be communicated with pipette on the sidewall of sleeve pipe and in this pipeline, be provided with the output check valve, pipette is extremely external by bottle cap, be the L shape, stick harness is from top to bottom implanted in the sleeve pipe of plunger device and is matched in clearance, the top of stick harness is provided with drawing handle, and a side of drawing handle is provided with vernier, is mutually the right angle overlap joint with the scale that is fixed on the bottle cap.
As further improvement of the utility model, described feed liquor check valve and output check valve are the float-type check valve.
As further improvement of the utility model, restricted snap ring on scale.
Laboratory of the present utility model adjustable quantitative pipettor, reasonable in design has been cancelled the design of spring, has increased output, input check valve, makes easy and simple to handlely, quick, and it is more accurate to move liquid.
Description of drawings
Figure of description is the structural representation of laboratory of the present utility model with the adjustable quantitative pipettor.
The specific embodiment
Laboratory of the present utility model adjustable quantitative pipettor is medical treatment, chemical industry, a scientific research department technical tool commonly used, be by plunger decide the journey activity, shape will negative pressure sucks quantitative liquid and crosses to the liquid in the container being moved into another function in container down.Scheme of the present utility model is to be made of solution bottle 1, plunger device 2, post chi 3 and pipette 4.The bottom that plunger device 2 is implanted in the solution bottle 1 by the bottle cap 5 of solution bottle 1, the sleeve pipe 6 and the bottle cap 5 of plunger device 2 fix, the lower end of sleeve pipe 6 is connected with inlet 7, be provided with feed liquor check valve 8 in the inlet 7, be communicated with pipette 4 on the sidewall of sleeve pipe 6, and in this pipeline, be provided with output check valve 9, pipette 4 passes through bottle cap 5 to external, be the L shape, stick harness 10 is from top to bottom implanted in the sleeve pipe 6 of plunger device 2 and is matched in clearance, the top of stick harness 10 is provided with drawing handle 11, and a side of drawing handle 11 is provided with vernier 12, be mutually the right angle overlap joint with the scale 3 that is fixed on the bottle cap 5.Described feed liquor check valve 8 and output check valve 9 are the float-type check valve.
Restricted snap ring 13 on scale 3, the control stick harness is range of operation up and down, guarantees the pipettor safe handling.
