Abstract
A catheter composite washing device includes the corrosion resistance vessel, sealing plug, filter, gas (liquid) tube, and screw, and it is characterized by that the sealing plug 7 has a gas chamber 21, and one end of the jet 16 is located at the top of the gas chamber 20, another end connects the atmosphere through the screw 17, and the exhausting gas (liquid) tube 15 and the jet 16 are located in the gas chamber 21 together, and the gas chamber 21 separate the inside gas and liquid with the filter 23. Compared with conventional manual, close distance exposure operation, the invention not only avoids the loss of the processing sample, but also significantly improves security, and effectively solving the rapid sample washing filtering problem of mass samples.
Description
One, technical field
The invention belongs to a kind of device, especially can realize the device of many reagent wash filtration tiny samplers in the experiment of animal and plant anatomy with liquid dissolving washing, separating solids material.
Two, background technology
The conduit composite technology is a common research method in a kind of animal and plant anatomy experiment.Generally all adopt styrene monomer is penetrated into the animal and plant catheter interior, after treating that styrene monomer solidifies, utilize the concentrated sulphuric acid to remove polysaccharide component on the cell membrane earlier, the mixed liquor that utilizes hydrogen peroxide and glacial acetic acid to constitute is again removed the lignin composition in the cell membrane, washing by soaking can be removed the organic matter of conduit composite outside so repeatedly; Use the acid solution of distilled water flush away conduit composite outside at last, the conduit composite that obtains promptly can carry out microexamination, in order to the morphosis of research animal and plant inside.
At present in the laboratory, during trickle sample in the washing and filtering reagent, adopt directly action of gravity to leach substantially, or sample is fixed on dull and stereotyped simple hand operation of going up with the reagent flushing by reagent.Because the used concentrated sulphuric acid, hydrogen peroxide and glacial acetic acid etc. all have very strong corrosivity or very strong pungency in the experiment, danger manual, closely exposure operation is very big; In addition, the speed of these operated wash filtered sample is slow, can't realize the quick washing and filtering to batch samples.
In experimentation, when soaking plant sample, because carbonification with the concentrated sulphuric acid, solution all becomes black, add that conduit composite is thin as hair, the length of some sample is less than 1mm, therefore how to proceed to next link and don't the sample lost in the processing is an individual very big problem.When especially handling batch samples, this problem is particularly outstanding.
Three, summary of the invention
Existing inconvenience when the objective of the invention is at conduit composite processing batch samples is sought a kind of new special filtering device, the purposes that reach fast, safety realize many reagent wash filtration tiny samplers.
Technical solution of the present invention is: a kind of conduit composite washing device, and package unit is made up of anti-corrosion container, sealing-plug, filter screen, gas (liquid) pipe, cock etc., it is characterized in that being provided with in the sealing-plug 7 gas chamber 21, and:
A. an end of air jet pipe 16 is positioned at gas chamber top 20, and the other end communicates with atmosphere by cock 17;
B. (liquid) pipe 15 of bleeding is in together in the gas chamber 21 with air jet pipe 16;
C. gas chamber's 21 usefulness filter screens 23 are isolated with gas, liquid in the container.
In order to reach the purpose of control air-flow, can also be processed into back taper to gas chamber 21.
This device is to utilize external vacuum pump 28 to bleed, and makes that container is inside and outside to be produced pressure differential and carry out work.When container inner pressure was lower than atmospheric pressure, different liquid reagents just can controlledly enter and the sucking-off container, to realize dissolving, corrosion and the washing operation to sample.Because sample is small, be easy to adhere to and stop up filter screen 23, can be controlled in this moment and produce a suitable negative pressure in the container, and by the cock 17 suitable air jet pipes 16 of opening, outside air will enter gas chamber 21 and impact attached to the sample on the filter screen 23, reaches the purpose of design of continuous high-efficient work.
Four, description of drawings
Fig. 1 is the structural representation of conduit composite washing device, among the figure: 1. sebific duct, 2. feed tube, 3. air inlet (liquid) pipe, 4. cock, 5. cock, 6. three-way pipe, 7. sealing-plug, 8. container bottle neck, 9. air inlet (liquid) mouthful, 10. filter screen, 11. anti-corrosion containers, 12. liquid level, 13. samples, 14. sebific ducts, 15. bleed (liquid) pipe, 16. air jet pipe, 17. cocks, 18. faucet holes, 19. puff prots, 20. gas chamber top, 21. gas chamber, 22. (liquid) mouths of pipe of bleeding, 23. filter screens.
Fig. 2 is the plan structure synoptic diagram of sealing-plug 7, and 24 is the sealing-plug side among the figure, and 25 is the sealing-plug bottom surface, and all the other number same Fig. 1;
External device synoptic diagram when Fig. 3 is the replica washing operation, 26,27 are respectively external surge flask among the figure, and 28 is vacuum pump.
Five, embodiment
Exemplary embodiments:
Make anti-corrosion container 11 with 200ml triangle glass bottle;
Make sealing-plug 7 with the acid and alkali-resistance rubber that the natural rubber material is synthetic, the height of sealing-plug 7 is that 40mm, mean diameter are φ 35mm, and the degree of depth of gas chamber 21 is that 15mm, mean diameter are φ 17mm;
With the aperture is that the nylon net cloth (Zhejiang Tian Yuan filter cloth company limited product) of 20 μ m is made filter screen 23,10.
Sucking-off, the exhaustion of cleansing solution for convenience, whole device can tilt even be inverted operation during work, because the air pressure in the container is less than or equal to atmospheric pressure all the time, the obscission of sealing-plug 7 can not take place generally.
Be used for replica washing milpa conduit,, can obtain satisfied white conduit composite sample through the operation of about 8h.
The present invention is manual with routine, closely the exposure operation is compared, because dissolving, corrosion and washing process are all operated in the container of sealing, not only avoided losing the sample problem in the processing, and security improves greatly, solved the quick washing and filtering problem of batch samples effectively.
