Abstract
The present invention discloses a novel pipette including a pipet, a first suction pipe, a suction device, a second suction pipe and a valve, one end of the pipet is a suction-in port; the first suction pipe includes an upper tube and a lower tube in breaking connection, the lower tube is in communication with the pipet, the upper tube is in communication with the outside, the suction device is provided with a suction port; the second suction pipe is in communication with the suction port of the suction device; the valve is a three-way valve, the valve is arranged in the junction position of the upper tube, the lower tube and the second suction pipe, the three-way valve comprises at least a first state and a second state, when the three-way valve is in the first state, the three-way valve only communicates the upper tube and the lower tube, and when the three-way valve is in the second state, the three-way valve only communicates the lower tube and the second suction pipe. Through adjusting of the three-way valve, the state of the pipet is fast switched, and after the pipet sucks a liquid, simple and rapid communication with the outside world is facilitated, so that excess solution release in the pipet is more simple and convenient, accuracy is high, and labor working intensity during operating process can be reduced.
Description
Technical field
The present invention relates to pipette, especially relevant with the structure of accurately moving liquid of pipette.
Background technology
Pipette is a kind of measuring device being used for accurately pipetting certain volume solution.Usually again graduated for tool straight shape glass tube is called pipette, the liquor capacity that Novel pipette and pipette pipette can be accurate to 0.01mL usually.
Several steps such as pipette operation is divided into washing (chromic acid lotion, running water, distilled water)-treat imbibition rinse-draw solution-regulating liquid surface-releasing solution-clean to dry.Wherein the operation of regulating liquid surface is more difficult, at present, when solution is drawn to more than graduation mark, usually need to coordinate thumb to pin the mouth of pipe with right hand forefinger, unclamp slightly the mouth of pipe (can slightly rotate Novel pipette or pipette), to make in pipe solution slowly flow out from end opening, solution concave meniscus and graduation mark tangent time, compress the mouth of pipe with this two finger immediately, a moment of pausing moves in container.In the existing operating process by the scale of right hand forefinger cooperation thumb control adjustment Novel pipette mouth; affect very large by individuality; when operating unskilled, the dynamics of finger is wayward; and right hand forefinger is easily tired; often excess solution can be released; accuracy is greatly affected, and even causes pipetting solution-operated failure.
Summary of the invention
For problems of the prior art, object of the present invention is for providing a kind of easy to operate, accurately and reduce the Novel pipette of hand labor intensity.
For achieving the above object, the invention provides following technical scheme:
A kind of Novel pipette, comprising:
Pipette, described pipette one end is suction inlet;
First suction pipe, described first suction pipe comprises can the top tube and down tube that connect of break-make, and described lower pipe is communicated with described pipette, and described upper pipe is communicated with extraneous;
Aspirator, described aspirator is provided with pump orifice;
Second suction pipe, described second suction pipe is connected with the described pump orifice of described aspirator;
Valve, described valve is triple valve, described valve is arranged on the meet of described upper pipe, described lower pipe and described second suction pipe, described triple valve at least comprises the first state and the second state, described triple valve be only communicated with when described first state described on pipe and described lower pipe, described triple valve is only communicated with described lower pipe and described second suction pipe when described second state.
Further, described triple valve also comprises the third state, described triple valve be only communicated with when the described third state described on pipe and described second suction pipe.
Further, described aspirator is ear washing bulb.
The present invention compared with prior art, by adjustment triple valve in the present invention, the state of quick switching pipette, be in communication with the outside quickly and easily after facilitating pipette pumping liquid, thus make that the release of managing interior redundant solution is more simple and convenient, accuracy is higher, reduce the hand labor intensity in operating process.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail:
Fig. 1 is Novel pipette structural representation of the present invention.
Detailed description of the invention
The exemplary embodiments embodying feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various changes in different embodiments, it neither departs from the scope of the present invention, and explanation wherein and accompanying drawing are the use when explain in itself, and is not used to limit the present invention.
As shown in Figure 1, in the present embodiment, Novel pipette 1 is made up of pipette 11, ear washing bulb 12, triple valve 13, first suction pipe 14 and the second suction pipe 15, and wherein the first suction pipe 14 is divided into again pipe 141 and lower pipe 142.Concrete syndeton is: lower pipe 142 is communicated with pipette 11, and upper pipe 141 is communicated with the external world, and triple valve 13 is arranged at the meet of pipe 141, lower pipe 142 and the second suction pipe 15, and the second suction pipe 15 is communicated with the pump orifice of ear washing bulb 12.
In the present embodiment, triple valve 13 comprises the first state, the second state and the third state.Wherein, triple valve 13 is only communicated with pipe 141 and lower pipe 142 when the first state; Pipe 142 and the second suction pipe 15 under triple valve 13 is only communicated with when the second state; Triple valve 13 is only communicated with pipe 141 and the second suction pipe 15 when the third state.
The implementation process of the present embodiment is as described below: first extrude air in ear washing bulb 12, being inserted by pipette 11 treats in imbibition, adjustment triple valve 13 to the second state, loosen ear washing bulb 12, solution is made to suck in pipette 11, when liquid level rises to more than setting graduation mark, adjustment triple valve 13 to the third state, now ear washing bulb 12 restores to the original state, liquid surface static in pipette 11, then slowly triple valve 13 to the first state is adjusted, liquid level in pipette 11 is slowly declined, when solution concave meniscus and setting graduation mark are tangent, adjust triple valve 13 to the second state or the third state immediately, solution in pipette 11 is no longer flowed out.Then pipette 11 is moved in container (not shown), tip is close to inwall, adjustment triple valve 13 to the first state, vertically makes solution freely interior along vessel wall portions from pipette 11, rotates pipette 11 gently and stop about 15 seconds after solution flows to end.Finally take out pipette 11, pipette solution-operated and complete.Pipette 11 is clean with distilled water flushing, for subsequent use.
The present invention compared with prior art, by adjustment triple valve 13 in the present invention, the state of quick switching pipette 11, be in communication with the outside quickly and easily after facilitating pipette 11 pumping liquid, thus make that the release of redundant solution in pipette 11 is more simple and convenient, accuracy is higher, reduce the hand labor intensity in operating process.
Technical scheme of the present invention is disclosed as above by preferred embodiment.The change that those skilled in the art do when should recognize the scope and spirit of the present invention disclosed in the claim do not departed from appended by the present invention and retouching, within the protection domain all belonging to claim of the present invention.
