Description
Technical field
The utility model relates to a kind of pipette, especially a kind of quick adjustment-free liquid level pipette.
Background technology
Existing pipette as ear washing bulb, measuring pipette, single mark suction pipe be used for imbitition time there are the following problems:
1, measuring in liquid process, pressing improper or cross loose tension, quick and precisely can not measure liquid volume, easily causing again liquid to suck in air bag, if strong acid or organic reagent class I liquid I, be then easy to corrode air bag, ear washing bulb is damaged or the lost of life.
2, compared with some pipette existing marks suction pipe with traditional ear washing bulb, measuring pipette, list, required liquid volume can be taken, but pipetting operation inconvenience in liquid process, simply, fast, accurately can not realize measuring of liquid.
Utility model content
Problem to be solved in the utility model is to provide a kind of quick adjustment-free liquid level pipette, and described pipette can the solution of accurate weighing certain volume, liquid can be avoided again to be inhaled in ear washing bulb, weigh simple, convenient, quick.
In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in that
A kind of quick adjustment-free liquid level pipette, described pipette comprises ear washing bulb, suction pipe main body and suction nozzle, and ear washing bulb is communicated with suction pipe body top, and suction pipe bottom part body is provided with suction nozzle; The upper tube of suction pipe main body, middle part solution cavity and lower tube integral type connect, and upper tube and solution cavity junction, middle part are provided with circular closing in, are provided with ellipse and close up, be built-in with spheroid in the solution cavity of middle part between middle part solution cavity and lower tube.
Further, described ear washing bulb is fixedly connected with by fixture with suction pipe body top.
Further, described upper tube internal diameter is greater than circular closing in diameter, and sphere diameter is greater than circular closing in diameter, and between the long axis length and minor axis length of ellipse closing in, lower tube internal diameter is less than or equal to the oval semi-minor axis length closed up.
Further, described suction pipe main body wall thickness 1mm, wherein upper tube internal diameter 6mm, circular closing in diameter 4mm, sphere diameter 6mm, middle part solution cavity internal diameter 12mm, long axis length and the minor axis length of oval closing in are respectively 10mm, 4mm, lower tube internal diameter 4mm.
Further, described suction pipe main body is glass tube.
Further, described spheroid is polytetrafluoroethylene (PTFE) georama, and density is 0.55g/cm
3, most organic reagent and solution density are between 0.7 ~ 1.1, and this density sphere can ensure there is a hemisphere when imbibition in solution, and imbibition to ensureing without air between spheroid and solution during sealing state, and then ensures the accurate of liquid absorption.
The utility model beneficial effect compared to existing technology:
The utility model structure is simple, makes easily, and easy to operate, work efficiency is remarkable, can either the solution of accurate weighing certain volume, and solution can be avoided again to be inhaled in ear washing bulb.Specifically:
(1) Conventional pipettes have two part form, pipette liquid be need both hands with the use of, this utility model one hand can complete.
(2) this pipette need not adjust liquid level to graduation mark, but draws the liquid of ormal weight volume by bead sealing function.
(3) this pipette is used only to need two steps, imbitition, tapping, simple and quick.
(4) Conventional pipettes needs regulating liquid surface, and because reading and sight line difference can cause comparatively big error, this pipette can avoid error.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is using state schematic diagram of the present utility model.
In figure: 1-ear washing bulb; 2-fixture; 3-upper tube; 4-circle closes up; Solution cavity in the middle part of 5-; 6-spheroid; 7-ellipse closes up; 8-lower tube; 9-suction nozzle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of quick adjustment-free liquid level pipette, described pipette comprises ear washing bulb 1, suction pipe main body and suction nozzle 9, and ear washing bulb 1 is communicated with suction pipe body top, and suction pipe bottom part body is provided with suction nozzle 9; The upper tube 3 of suction pipe main body, middle part solution cavity 5 and lower tube 8 integral type connect, and upper tube 3 and middle part solution cavity 5 junction are provided with circularly closes up 4, is provided with ellipse and closes up 7, be built-in with spheroid 6 in middle part solution cavity 5 between middle part solution cavity 5 and lower tube 8.
On the basis of technical scheme described in the above embodiments, described suction pipe main body is glass tube, and ear washing bulb 1 is fixedly connected with by fixture 2 with suction pipe body top.
Described suction pipe main body wall thickness 1mm, wherein upper tube 3 internal diameter 6mm, circular 4 diameter 4mm, spheroid 6 diameter 6mm, the middle part solution cavity 5 internal diameter 12mm of closing up, long axis length and the minor axis length of oval closing in 7 are respectively 10mm, 4mm, lower tube 8 internal diameter 4mm.
Described spheroid 6 is polytetrafluoroethylene (PTFE) georama, and density is 0.55g/cm
3, most organic reagent and solution density are between 0.7 ~ 1.1, and this density sphere can ensure there is a hemisphere 6 when imbibition in solution, and imbibition to ensureing without air between spheroid 6 and solution during sealing state, and then ensures the accurate of liquid absorption.
Operation principle of the present utility model and the course of work:
1), during imbitition, firmly extruding ear washing bulb 1, puts into the utility model and treats imbitition, slowly loosen ear washing bulb 1 to make to form negative pressure in pipette chamber, liquid rises, and liquid carries spheroid 6 to circle and closes up 4, and now liquefied gas is not because the sealing function of spheroid 6 is all by circle closing in 4;
2) when releasing liquid, only firmly need extrude the liquid that ear washing bulb 1 can draw and release, spheroid 6 just can fall after rise naturally, and spheroid 67 has gap with oval closing in, and liquefied gas can be allowed to pass through.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
