Description
Technical field
The utility model belongs to experiment device, seeps more particularly to one kind is related suitable for the subjects such as biology, chemistry
The related experiment of saturating phenomenon, helps experimenter to more fully understand the U-shaped permeability apparatus of chemosmotic experiment.
Background technique
Currently used permeability apparatus is generally formed by the glass equipment Simple assembled such as long neck funnel and beaker, concrete operations
Method is to be upside down in the beaker equipped with solution or water after long neck funnel oral area pricks upper semi-permeable membrane, then the mouth under long neck funnel
End injection experiments complete permeability test with reagent.In practical operation, since long neck funnel mouth diameters are larger, need to make
Semi-transparent membrane area it is larger, if selecting biomembrane (such as eggshell membrane) so big as being difficult to successfully obtain if semi-permeable membrane
The semi-permeable membrane of area, even if the biological semi-permeable film for acquisition so large area of having the honor, is fixed on long neck funnel mouth for this semi-permeable membrane
Portion is also not the thing being easily done, and semi-permeable membrane damage easily occurs, ligatures the problems such as insecure；If selecting commercially available glass
If glass paper does semi-permeable membrane, experimental phenomena is not obvious, and the time for generally requiring several days can just see that liquid level is poor, and is needed
There is the solution of semi-permeable membrane two sides sufficiently large concentration difference to be likely to occurring desired effect, or can't see ideal experiment at all
Effect.Therefore, because the problem of real operation difficulty, in the daily teaching experiment of the inreal approaching students of permeability test.This
Largely affect interest that student learns this partial knowledge and to the understanding of theoretical knowledge.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of experiment U-shaped permeability apparatus.
The technical solution of the utility model is summarized as follows:
U-shaped permeability apparatus is tested, is made of the first L-type pipe 1, rubber washer 5, semi-permeable membrane 6 and the second L-type pipe 2；Second
The left end end of L-type pipe is interface 9, and the internal diameter of interface 9 is greater than the second L-type pipe internal diameter of tube body, and the outer surface of interface
It is provided with outer grinding port layer；The right end end of first L-type pipe is birdsmouth 10, and the outer diameter of birdsmouth 10 is greater than the first L-type pipe tube body
The internal diameter of outer diameter, birdsmouth is greater than the first L-type pipe internal diameter of tube body, and the inner surface of birdsmouth is provided with interior ground layer；In grafting
Semi-permeable membrane 6 and rubber washer 5 are set gradually inside-out in mouthful；Interface is flexibly connected with birdsmouth.
Preferably, the vertical tube outer surface of the first L-type pipe is provided with the first graduation mark 7, in the vertical tube appearance of the second L-type pipe
Face is provided with the second graduation mark 8, and the first graduation mark and the second graduation mark are contour.
The advantages of the utility model:
The utility model structure is simple, simple, detachable, cleaning and Reusability are installed in operation.
Detailed description of the invention
Fig. 1 is the U-shaped permeability apparatus decomposition diagram of experiment of the utility model.
Fig. 2 is the U-shaped permeability apparatus structural schematic diagram of experiment of the utility model.
Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
U-shaped permeability apparatus is tested, Fig. 1 and Fig. 2 are seen, by the first L-type pipe 1, rubber washer 5, semi-permeable membrane 6 and the second L-type
Pipe 2 forms；The left end end of second L-type pipe is interface 9, and the internal diameter of interface 9 is greater than the second L-type pipe internal diameter of tube body, and inserts
The outer surface of interface is provided with outer grinding port layer；The right end end of first L-type pipe is birdsmouth 10, and the outer diameter of birdsmouth 10 is greater than the
The internal diameter of one L-type pipe outer tube diameter, birdsmouth is greater than the first L-type pipe internal diameter of tube body, and the inner surface of birdsmouth is provided with interior mill
Mouth layer；Set gradually semi-permeable membrane 6 and rubber washer 5 inside-out in interface；Interface is flexibly connected with birdsmouth.
Preferably, the vertical tube outer surface of the first L-type pipe is provided with the first graduation mark 7, in the vertical tube appearance of the second L-type pipe
Face is provided with the second graduation mark 8, and the first graduation mark and the second graduation mark are contour.
Using the U-shaped permeability apparatus of experiment of the utility model, can be selected common egg shell inner membrance, Chinese cabbage petiole,
The biological semi-permeables films such as onion, big Bulbus Allii Fistulosi endepidermis are tested, and the semi-permeable membrane more bigger than rubber washer size in the present apparatus is cut,
The semi-permeable membrane is affixed on rubber washer, and is caught in interface together, it is very thin at the ground layer of interface outer surface to apply one layer
It is inserted into finishing device in the birdsmouth of the second L-type pipe after vaseline to install, subsequent experimental operation can be carried out.
Graduation mark 7 and 8 set by first L-type pipe and the second L-type pipe equal-height position is groove type groove, this groove both can be used
Compare the reference of two sides L pipe liquid level in as experimentation, and available rubber band carries out reinforcing behaviour in two sides L pipe groove
Make, prevents U-tube bottom junctions loosening in experimentation from causing leakage.
