Description
Technical field
The utility model relates to experimental apparatus technical field, specially a kind of separatory funnel with piston cap.
Background technique
Separatory funnel is a kind of laboratory common experimental vessel, is pharmacy, the experiment such as to extract in chemical experiment essential
Instrument, be usually made of bucket cover, bucket body and adapter.In the experimental implementations such as extraction, shake what complementation in funnel mixed
Two kinds of liquid, are allowed to be sufficiently mixed, and low boiling point solvent is volatile when due to shaking, need to deflate to balance inside and outside funnel at this time
Pressure, liquid is flowed out by lower part in order to prevent, raises adapter part in the separatory funnel of operation with traditional, is put in shaking
Gas, at this time if bucket cover unsealing is good, liquid may be from outflow suitable for reading, and it is extremely inconvenient to operate.In addition, also will be above when liquid separation
Bucket cover remove and could release liquid by adapter, operation in this way is also inconvenient.On separatory funnel bucket cover disclosed by the utility model
There is teflon piston, in operation, bucket cover piston opening need to can only be played when shaking is deflated or releases liquid flat
The effect of weighing apparatus funnel external and internal pressure.
Utility model content
It is difficult that the purpose of the utility model is to overcome above-mentioned background techniques, provides a kind of separatory funnel with piston cap.
In order to achieve the above objectives, the technical solution of use are as follows: a kind of separatory funnel with piston cap includes bucket body and bucket
Lid, the bucket body lower end are equipped with adapter, and the adapter is equipped with tail pipe piston, and opening is equipped with above the bucket body, described
Bucket cover is set in the opening above bucket body；The bucket cover center is equipped with the bucket cover stomata to connect up and down, is additionally provided with energy on bucket cover
Block the bucket cover piston of the bucket cover stomata；The tail pipe piston and bucket cover piston are equipped with aperture, are made by rotation piston small
Hole is connected to up and down.
Further, the bucket body is that frosted mouth is connect with bucket cover.
Further, the bucket cover stomata is round or square aperture.
Further, the bucket cover piston is fixed on bucket cover by rubber band.
Further, the tail pipe piston is fixed on adapter by rubber band.
Further, the bucket cover, bucket body and adapter are all made of glass material.
Further, the bucket cover piston and tail pipe piston use polytetrafluoroethylene (PTFE) material.
Using the above scheme have the beneficial effect that this separatory funnel with piston cap has traditional single-piston liquid separation leakage
The use function of bucket, there is bucket cover piston and bucket cover stomata on bucket cover, and when operation opens bucket cover piston, plays inside and outside balance funnel
The effect of pressure must be such that funnel lower end tilts upward and open tail adapter tube piston ability when overcoming the shaking of traditional separatory funnel
It the drawbacks of deflation, can be to open the deflation of bucket cover piston in shaking to balance funnel external and internal pressure when use；The bucket cover and bucket
Body is the connection of frosted mouth, is prevented during the experiment, and outside air intracorporal air of running into or struggle against is run out of, and is made inside and outside bucket body
Balance is not achieved in air pressure, influences the accuracy of experiment, and it is to play a fixed function to piston that a rubber band is tied up at piston, prevents
Only it falls off in doing experimentation, influences the accuracy of experiment, followed by after finishing experiment cleaning, piston is enable to lead to
It crosses rubber band to tie up on bucket cover stomata and adapter, prevents from next time from doing experiment piston model on not；In addition, traditional separatory funnel
When releasing liquid by funnel, it is necessary to take down upper end bucket cover, operate so also cumbersome.Point with piston cap of the utility model
Liquid funnel, it is easy to operate, improve conventional efficient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of separatory funnel of the utility model with piston cap.
In figure, 1- bucket cover, 2- bucket cover stomata, 3- bucket cover piston, 4- bucket body, 5- adapter, 6- tail pipe piston.
Specific embodiment
It is further described the utility model below with reference to examples and drawings, but the utility model is not limited only to following implementations
Example, it is anticipated that for those skilled in the art in the case where combining the prior art, there may be many variations for performance.
Such as Fig. 1, a kind of separatory funnel with piston cap includes bucket body 4 and bucket cover 1, and 4 lower end of bucket body is equipped with adapter
5, the adapter 5 is equipped with tail pipe piston 6, and opening is equipped with above the bucket body 4, and the bucket cover 1 is frosted mouth company with bucket body 4
It connects；1 center of bucket cover is equipped with the bucket cover stomata 2 to connect up and down, and the bucket cover stomata 2 is round or rectangular aperture, bucket
The bucket cover piston 3 that can block the bucket cover stomata 2 is additionally provided on lid 1, the bucket cover piston 3 is fixed on bucket cover 1 by rubber band
On；The tail pipe piston 6 and bucket cover piston 3 are equipped with aperture, are connected to aperture up and down by rotating piston, the tail pipe piston
6 are fixed on adapter 5 by rubber band；The bucket cover 1, bucket body 4 and adapter 5 are all made of glass material；The bucket cover is living
Plug 3 and tail pipe piston 6 use polytetrafluoroethylene (PTFE) material.
When operator uses the separatory funnel with piston cap, the right hand can be held on bucket cover piston 3 and bucket body 4
Mouthful, left hand holds at tail adapter tube piston 6, and finger pushes down tail pipe piston 6, and when shaking passes through the right hand and constantly switchs bucket cover piston 3, side
Side is shaken to deflate, wait shake after stratification, bucket cover piston 3 and tail pipe piston 6 open simultaneously and can be put by when tapping body
Liquid out, it is ensured that the balance of air pressure in experiment；Bucket cover piston 3 plays external pressure in balance funnel in shaking deflation or tapping body
The effect of power improves the accuracy of experiment.
