The specific embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, the multistage microreactor of a kind of percussion flow of the present invention is to be overlaped by the access panel 14 of square reaction plate 10,12 and their both sides and base plate 16 to form. Wherein reaction plate 10,12 and base plate 16 are stainless steel and make, and its surface that is in contact with one another is all carried out surface finish by electrobrightening technology and handled, and can reach better seal.Access panel 14 is that corrosion-resistant glass is preferably made, and is used for the situation that observing response takes place.Reaction plate 10 and 12 thickness can determine as required that the thickness of first embodiment of the invention is 0.1mm.
As shown in Figure 2, be provided with a plurality of mutual disconnected grooves by mode reaction plates 10 such as etching or laser cutting, each groove all connects.Groove on the reaction plate 10 forms inlet 18 respectively, outlet 20 and jet 22.As shown in Figure 3, also be provided with a plurality of mutual disconnected grooves by modes such as etching or laser cutting on reaction plate 12, each groove all connects.Groove on the reaction plate 10 forms inlet 18 respectively, outlet 20 and little reative cell 24.The precision of processing mode such as etching or laser cutting processing is higher, and the both processing easily of mutual disconnected groove, also avoided on reaction plate 10 forming the tongue of strip, because reaction plate 10,12 is thinner, the distortion that is distorted easily of all fluted tongue in this both sides.
As shown in Figure 4, after reaction plate 10 and 12 overlaped, the groove on it had formed the capillary microchannel 26 that is communicated with.Capillary microchannel 26 is communicated with inlet 18 and outlet 20, comprising a plurality of end to end little reative cells 24, is connected by jet 22 between adjacent little reative cell 24.Two kinds of different reactant liquors 18 enter in the capillary microchannel 26 through entering the mouth, and pass through all little reative cells 24 successively, and continuous hybrid reaction therein is after export 20 and discharge.As shown in Figure 5, the inwall of the little reative cell 24 behind the jet 22 comprises bump wall 28.Bump wall 28 is over against jet 22, and with jet 22 in the reactant liquor flow direction that comes out become the obtuse angle.The width of jet 22 is 0.1mm; like this through the reactant liquor after jet 22 pressurization can high-speed impact to bump wall 28, liquid particles wherein can be crashed to pieces, have in addition can arrive micron order; add the bump back and produce turbulent flow, can be so that different reactant liquors fully mixes abundant reaction.
The multistage eddy current microreactor of a kind of chaos type of the present invention, the long 127mm of overall structure, wide 85mm, thick 24mm can be applicable in degenerative treatments, the molecular cloning experiment of preservation, enzyme reaction, nucleic acid and the protein of the preservation of sample, various enzymes that application of sample, gel reclaim before each step reaction, the PCR reaction, the pre-sex change of electrophoresis and serum solidify etc.Have higher economic value and practicality.
Above embodiment only is the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
