Description
Technical field
The utility model relates to a kind of pipettor.
Background technology
Pipettor is in such as laboratory, laboratory, the occasion of sample analysis room and so on widely uses, by operator, pipettor is repeatedly moved between extract container and test tube, so produce following drawback: one is that efficiency is low, such as under the situation that experiment sample amount is large, between extract container and test tube, mobile pipettor understands the time of at substantial repeatedly, the experiment progress of whole batch is caused to be affected, two is due to needs frequently movement between extract container and test tube, thus the manipulation strength of operator is large, three is there is the anxiety to extract pollution, cause experiment analysis results inaccurate, four is due to the frequent imbibition of needs, therefore extract container is in open state usually, so moving in liquid process, because extract is exposed in air for a long time, the pH value of extract can be made to change with air Long contact time, and the pH value of extract can cause the result of all experiment samples inaccurate once change.
Utility model content
Problem to be solved in the utility model is, there is provided a kind of structure simple accuracy fine-tunable pipettor, improve the precision of moving liquid and measuring, one contributes to significantly improving operating efficiency and uses and meets the numerous requirement of experiment sample and can obtain experimental result rapidly, be conducive to the extract in extract container being transferred in numerous test tubes in a continuous manner and using the manipulation strength alleviating operator, be of value to avoiding producing and extract polluted and uses the accuracy ensureing experiment analysis results, there is the harsh occasion being convenient to be applied to genetic analysis and so on, expansive approach field and the extract made in extract container and isolate from outer air, extract deterioration is avoided to damage pipettor.
For solving the problem, the utility model adopts following technical scheme:
A kind of pipettor, comprise sleeve, elastic suction nozzle, shirk button, pressure sensor and volume display, described volume display is arranged on sleeve, the inner chamber installing piston rod is had in described sleeve, described piston rod outside is provided with a back-moving spring, described inner chamber communicates with elastic suction nozzle, between described elastic suction nozzle and sleeve, sealing ring is installed, one end of suction nozzle is provided with blocking solution plug to inner chamber and this blocking solution plug is the blocking solution plug of gas-permeable, liquid-impermeable, the Volume Changes of described inner chamber is presented in volume display by pressure sensor, describedly shirk button and piston rod is synchronized with the movement, described piston rod part has one to finely tune circulator, described pressure sensor passes through together with connection with volume display.
As preferably: described inner chamber is medical polyvinyl, surface is through polishing.
As preferably: described sealing ring scribbles lubricating oil, and sealing ring is teflin ring.
As preferably: the shape of described sleeve external overall adhered shape finger.
The ergonomic designs adopted in this technical scheme is reliably convenient in the middle of practice, also possesses sight simultaneously, and the polishing of inner chamber and blocking solution plug accuracy when can ensure its work, the display screen at handle place can observe the volume pipetting liquid very easily.
The beneficial effects of the utility model are:
1. the utility model pipettor adopts pressure inductor once heavy dose ofly can get liquid, then shifts out liquid several times according to demand accurately, greatly reduces workload.
2. the accuracy when polishing of the utility model pipettor inner chamber and blocking solution plug can ensure its work, the display screen at handle place can observe the volume pipetting liquid very easily.
3. the utility model pipettor design comparison is simple, and structure member is less, greatly reduces production cost, comparatively easily can realize mass production.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of a kind of pipettor of the utility model.
Detailed description of the invention
Consult shown in Fig. 1, a kind of pipettor, comprise sleeve 1, elastic suction nozzle 2, shirk button 3, pressure sensor 4 and volume display 5, described volume display 5 is arranged on sleeve 1, it is just in time the place of finger grip, can be more convenient during use, ensure during installation that display 5 surface is relative with sleeve 1 surface to overlap, the inner chamber 7 installing piston rod 6 is had in described sleeve 1, the material of piston rod 6 wants corrosion resistance stronger, a back-moving spring 8 is installed in described piston rod 6 outside, described inner chamber 7 communicates with elastic suction nozzle 2, between described elastic suction nozzle 2 and sleeve 1, sealing ring 9 is installed, one end of suction nozzle is provided with blocking solution plug 10 to inner chamber 7 and this blocking solution plug 10 is blocking solution plugs of gas-permeable, liquid-impermeable, mainly in order to prevent the liquid stream of inner chamber 7 li out, the Volume Changes of described inner chamber 7 is presented in volume display 5 by pressure sensor 4, describedly shirk button 3 and be synchronized with the movement with piston rod 6, depositing when hook 11 can facilitate pipettor not use, described piston rod part has one to finely tune circulator 12.
Described inner chamber 7 is medical polyvinyl, can to change other use material as polyethylene etc. according to the difference pipetting liquid.
Described sealing ring 9 scribbles lubricating oil.
The place of the finger shape, particularly finger grip of described sleeve 1 external overall adhered shape people is provided with four grooves.
In use, shirk button 3 by finger extruding thus drive piston rod 6 to move, when loosing one's grip, back-moving spring 8 resets, and produces pressure difference and can allow elastic suction nozzle 2 imbitition.
The beneficial effects of the utility model are: the utility model pipettor adopts pressure inductor once heavy dose ofly can get liquid, then liquid is shifted out several times according to demand accurately, greatly reduce workload, the polishing of the utility model pipettor inner chamber and blocking solution plug can ensure accuracy during its work, the display screen at handle place can observe the volume pipetting liquid very easily, the utility model pipettor design comparison is simple, structure member is less, greatly reduce production cost, comparatively easily can realize mass production.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed in the new protection domain of this practicality and be as the criterion.
