Description

A kind of filtration pipettor
Technical field
The utility model relates to a kind of filtration pipettor.
Background technology
At present from solid and liquid hybrid solution or solid and semi-solid mixed solution the method for separating liquid mainly contain filter, suction filtration, centrifugal etc., these operations generally can only be carried out in laboratory, and operation sequence is more complicated, to experimenter and the certain requirement of equipment.The pipettor sold in the market all can only realize the operation pipetting liquid from liquid, does not possess in the function of to move in liquid process solid in mixing material, semi-solid components is filtered.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of novel structure, filtration pipettor easy to use.
The utility model adopts following scheme to realize: a kind of filtration pipettor, what comprise that one end has a convex mouth type inlet moves fluid cylinder, the described inlet moving fluid cylinder is provided with suction nozzle, describedly move in fluid cylinder the piston being provided with and being slidably matched with it, also comprise and stretch into move fluid cylinder inner chamber and the push rod be rotationally connected with pistons end by moving the fluid cylinder other end, be provided with the filter making Separation of Solid and Liquid between described suction nozzle and inlet, described in move fluid cylinder periphery wall and be provided with containing mark line.
Further, all adopt conical plug formula to removably connect between described filter and inlet and between filter and suction nozzle, in described filter, be provided with filter membrane, filter core or filter disc.
Compared with prior art, the utility model has following beneficial effect: this filtration pipettor novel structure, low cost of manufacture, easy to use, can accurate liquid extracting be realized, from solid-liquid mixed solution or solid-semi-solid mixed solution, liquid solution can be pipetted fast, and simple to operate, with low cost, each universities, scientific research institutions, inspection body etc. are all of great immediate significance.
For making the purpose of this utility model, technical scheme and advantage clearly understand, below by specific embodiment and relevant drawings, the utility model will be described in further detail.
Accompanying drawing explanation
Fig. 1 is the utility model embodiment 1 organigram;
Fig. 2 is the utility model embodiment 2 organigram;
Fig. 3 is the utility model embodiment 2 partial sectional view;
Number in the figure illustrates: 1-moves fluid cylinder, 2-inlet, 3-suction nozzle, 4-piston, 5-push rod, 6-filter, 7-containing mark line, 8-sleeve pipe, 9-push away handle, 10-block ring, 11-screwed hole, 12-lock-screw.
Detailed description of the invention
As Fig. 1 illustrates the utility model embodiment 1, a kind of filtration pipettor, what comprise that one end has a convex mouth type inlet 2 moves fluid cylinder 1, the described inlet 2 moving fluid cylinder 1 is provided with suction nozzle 3, describedly move in fluid cylinder 1 piston 4 being provided with and being slidably matched with it, also comprise and stretch into move fluid cylinder 1 inner chamber and the push rod 5 be rotationally connected with piston 4 end by moving fluid cylinder 1 other end, the filter 6 making Separation of Solid and Liquid is provided with between described suction nozzle 3 and inlet 2, described fluid cylinder 1 periphery wall that moves is provided with containing mark line 7, when pulling push rod 5, move in fluid cylinder 1 and form vacuum, fluid cylinder 1 is moved by sucking in solid-liquid mixed solution or solid-semi-solid mixed solution, device 6 filters solid or semi-solid components after filtration, liquid is inhaled into and moves in fluid cylinder, pull down filter 6 and suction nozzle 3, promoting push rod 5 can move in target container by the liquid rotating of absorption easily, simple to operate, realize pipetting liquid solution fast.
In the present embodiment, between described filter 6 and inlet 2 and between filter 6 and suction nozzle 3, all adopt conical plug formula to removably connect, in described filter 6, be provided with filter membrane, filter core or filter disc.
As Fig. 2 ~ 3 illustrate the utility model embodiment 2, the difference of the present embodiment and embodiment 1 is: in the present embodiment, the sleeve pipe 8 be slidably matched with pipette 1 is also arranged with in described pipette 1, described sleeve pipe 8 is placed on described push rod 5, and be provided with the screw thread matched between described push rod 5 lateral wall with described sleeve pipe 8 madial wall, quick drawing liquid can be realized when pulling push rod 5 and sleeve pipe 8 to move, and the fine setting of drawing liquid amount can be realized by rotating push-rod 5.
In the present embodiment, described push rod 5 is provided with away from piston 4 one end and pushes away handle 9, described moving on fluid cylinder 1 is arranged at block ring 10 away from described inlet 2 one end, moving on fluid cylinder 1 end of described block ring 10 place radially offers screwed hole 11, described screwed hole 11 is provided with the lock-screw 12 in order to locking sleeve 8.
The course of work of pipettor is filtered: unclamp lock-screw 12 in embodiment 2, push rod 5 is pulled to move fluid cylinder 1 by sucking in solid-liquid mixed solution or solid-semi-solid mixed solution, device 6 isolated by filtration falls solid or semi-solid components after filtration, liquid is inhaled into and moves in fluid cylinder, when piston 4 moves to close to required amount of liquid graduation mark, tighten lock-screw 12, when rotating push-rod 5 drives piston 4 to move to required amount of liquid graduation mark, realize accurate liquid extracting.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the 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.
