Background technology
Pipette uses comparatively extensive in laboratory, is the instrument of indispensability when measuring large quantity of fluid.Traditional pipette is glassware, mostly needs to carry out the cleaned rear liquid that just can measure other after using.First must carry out imbibition with rubber pipette bulb during use, then pin the opening part of pipette upper end with thumb, the thumb that comes up is to reach the object of releasing liquid, and whole imbibition process need both hands cooperation just can complete.After imbibition completes, wholely move in liquid process the upper end open place needing thumb to pin pipette all the time, the careless slightly situation that just there will be dropping liquid.
Moving after dropping liquid appears in liquid process, there is error in the liquid in pipette, needs imbibition again, and the liquid simultaneously dripped also likely can cause certain pollution to environment.Draw or releasing liquid time all to consume a large amount of time, and when releasing liquid as easy as rolling off a log generation error.In order to improve conventional efficient, need to provide a kind of novel pipette, to overcome the defect of existing laboratory apparatus.
Utility model content
The purpose of this utility model is to provide a kind of novel pipette, to solve the error that pipette must be assisted imbibition, the cleaning tedious steps such as body, liquid filtering with rubber pipette bulb and produce in the process of measuring.The utility model pipette also can be drawn and discharge quantitative liquid by experimental needs.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of Novel pipette, have the first body, one end of described first body is connected with column casing by connecting portion, and the other end is provided with filter, and column casing inside is provided with piston, and piston can move along its axis in column casing inside.Described piston is provided with piston rod, and one end of piston rod is connected with piston, and the other end stretches out the outside of column casing and is configured with handle.Described column casing is connected with the first body, and the middle part of the first body is provided with liquid storage cylinder.
Preferably, described connecting portion is funnel-form, and the small-caliber end of connecting portion is fixedly connected with the first body, and the heavy caliber end of connecting portion is fixedly connected with integral with column casing.
Preferably, the lateral wall of described first body is provided with scale.
Preferably, the internal diameter of described liquid storage cylinder is greater than the internal diameter at first other position of body, and the outline of liquid storage cylinder protrudes from the outline at first other position of body.
Preferably, described column casing is provided with limiting section away from one end of the first body, and limiting section can prevent piston from departing from column casing.
Preferably, described filter has the second body, and the second body and the first body are socketed, and be provided with filter chamber, be configured with screen pack in filter chamber in the middle part of it.
By adopting technique scheme, Advantageous Effects of the present utility model is: a kind of Novel pipette of the utility model, adopt and be configured with the column casing of piston and the integrative-structure of the first body, one-handed performance can be realized, get liquid rapidly and accurately, get in liquid process and complete filtration simultaneously, achieve the integration operation of getting liquid and filtration.Moving in liquid process, there will not be the situation of leakage, and evenly discharge liquid under the effect of the pressure.This Novel pipette eliminates assists imbibition, tedious steps such as cleaning body, liquid filtering etc. with rubber pipette bulb, quick and easy to use.
Accompanying drawing explanation
Fig. 1 is the structural principle schematic diagram of a kind of Novel pipette of the utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
Composition graphs 1, a kind of novel pipette, there is the first body 1, one end of described first body 1 is connected with column casing 2 by connecting portion 6, the other end is provided with filter, and column casing 2 inside is provided with piston 3, and piston 3 can move along its axis in column casing 2 inside, described column casing 2 is provided with limiting section 7 away from one end of the first body 1, and limiting section 7 can prevent piston 3 from departing from column casing 2.Described connecting portion 6 is funnel-form, and the small-caliber end of connecting portion 6 is fixedly connected with the first body 1, and the heavy caliber end of connecting portion 6 is fixedly connected with integral with column casing 2, and described column casing 2 is connected with the first body 1.Described column casing 2, connecting portion 6 and the first body 1 are the integrative-structures be made up of polypropylene plastics, and the first body 1 is elongated, can be deep in the container of long-neck and get liquid.Described filter has the second body 9, second body 9 and the first body 1 is socketed, and is provided with filter chamber 10, is configured with screen pack 11 in filter chamber 10 in the middle part of it.
Described piston 3 is provided with piston rod 5, and one end of piston rod 5 is fixedly connected with the middle part of piston 3, and the other end stretches out the outside of column casing 2, and the end of piston rod 5 is configured with handle 8.The middle part of described first body 1 is provided with liquid storage cylinder 4, and the inside of liquid storage cylinder 4 is communicated with the inside of the first body 1, and liquid storage cylinder 4 can be used for storage of liquids, and the first body 1 being configured with liquid storage cylinder 4 can increase each gets liquid measure.The internal diameter of described liquid storage cylinder 4 is greater than the internal diameter at other position of the first body 1, and the outline of liquid storage cylinder 4 protrudes from the outline at first other position of body 1.The lateral wall of described first body 1 is provided with scale, and the lower end of the first body 1 is closing-in structure, no matter is the effect that all can reach when getting liquid or releasing liquid at the uniform velocity.
