Description
Technical field
The utility model relates to a kind of novel microballoon screening chip, from use, is a kind of one three substrate microballoon screening chip of material screening.
Background technology
Microflow control technique is the microscale experiment room technology grown up in recent years, is mainly used in the fields such as biomedical and chemical monitoring, and in the Synthesis and applications of materialogy, research application is few.At present, along with materialogy is receiving the technical development in micro-field, materialogy to receive slight grain research and use more and more, particularly the preparation of other particulate of micro/nano level and screening, be more concerned by people.In the synthesis preparation of many composite particles, be utilize liquid as carrier mostly.The complex microsphere of the micro/nano level of synthesis is also formed in the solution.So how screen rapidly the qualified microballoon of the composite demand size in solution, be not only the problem that aspect needs solution prepared by current material.Also be that microflow control technique applies to the direction gone in the engineering field of the preparation of microballoon simultaneously.
Therefore, need the microballoon screening chip of the microflow control technique developing a kind of specialty, for the preparation aspect of material engineering.
Summary of the invention
The technical solution of the utility model is: a kind of three substrate microballoon screening chips, it is primarily of comprising three base hard sheets, the chip of the two panels up and down composition of three layer photoetching glue, it is characterized in that: have sample holes in one end of upper chip, one end, main channel of long 10mm is communicated with sample holes, the other end is divided into Liang Tiao subchannel, both sides, every bar subchannel, respective UNICOM one bar grizzl(e)y gating road.Two bar grizzl(e)y gating roads respectively towards the continuous zigzag in inner side, symmetrical 90-degree right-angle turning, finally import together at the medium line of main channel, the passage long by 5mm is connected with sample outlet hole.The arrangement of passage is convenient in design.
Each of every bar grizzl(e)y gating road is processed with a micro-port of screening to the right angle in passage, and the micro-port of each screening connects a little collecting pit; Little collecting pit, is communicated with the storage pool of bottom sheet chip by the vertical through hole at center, pond.Bottom sheet chip has rectangular A collector unit, B collector unit, C collector unit 3 collector units, correspond to the little collecting pit in 3 sections of passages in two bar grizzl(e)y gating roads of a chip and 3 sections respectively.Employing gravity flows, and collects the microballoon of screening.Each collector unit forms a pressure regulation cavity at upper and lower 2 layers of base hard sheet, is provided with the breather pipe that penetrates into upper slice chip surface at pressure regulation cavity center position.The purpose of design of pressure regulation cavity and breather pipe is to provide negative pressure or malleation.
The pressure regulation cavity both sides of A collector unit, B collector unit, are processed with lower than pressure regulation cavity, the storage pool that takes the shape of the letter U immediately below the little collecting pit in corresponding two bar grizzl(e)y gating roads, the centre bore of the storage pool of each U-shaped then 2 little collecting pits.The object of the storage pool of U-shaped is to reduce storage pool, relatively expands pressure regulation cavity size ratio with it, is beneficial to pressure regulation, reduces memory space simultaneously, alleviate the pressure of storage pool sample output passage.A storage pool sample output passage and storage pool is had to portal separately respectively in the rectangle both sides of A collector unit, B collector unit.Be convenient to discharge screening microballoon fast, raise the efficiency, reduce passage flow pressure.In the middle of the rectangle pressure regulation cavity of C collector unit be one higher than the round platform of storage pool, round platform purpose of design is also relatively expand pressure regulation cavity size ratio with it, is beneficial to pressure regulation, reduces memory space simultaneously, alleviate the pressure of storage pool sample output passage.Only there are a storage pool sample output passage and a storage pool to portal in rectangle side.
In technique scheme, described upper slice chip is that the photoresist that even 2mm is thick prints out after passage through mask plate, surface channel is counter to be upward attached on a slice base hard sheet, and face is airtight is on a photoresist pasted with a slice base hard sheet, seals up the passage of a chip.Such design is convenient to reverse mould to produce a chip in batches.Base hard sheet has through hole, then attaches one deck photoresist above, and the breather pipe on fixing hole and storage pool portal and the tube connector on sample outlet hole.Object utilizes photoresist elasticity, installs sealed hair tubule.Go up a chip like this, just have bottom a slice base hard sheet, last layer is photoresist layer, then is a slice base hard sheet, then is one deck photoresist layer.Described bottom sheet chip is a slice base hard sheet, and last layer is photoresist layer.Thus, the utility model three base hard sheets, the chip of the two panels up and down composition of three layer photoetching glue.Base hard sheet comprises silicon chip, sheet glass, sheet metal, plastics composite sheet.
In technique scheme, each single channel of described screening passage has more than 14 90 ° of right-angle turnings, the long 6mm in turning, wide 2mm.Quantity and length, ensure that the efficiency of screening.
In technique scheme, the size of described bottom sheet chip A collector unit, B collector unit, the C collector unit respectively micro-port of screening of 3 sections of passages in two bar grizzl(e)y gating roads of corresponding upper slice chip, consistent unified in every section, the micro-port size of screening between 3 sections is different, ascending arrangement; The width screening micro-port has 3 specifications at each three substrate chips, and size is between 5 μm ~ 300 μm.Such as: the micro-port dimensions of screening between 3 sections of two bar grizzl(e)y gating roads of three substrate chips: 300 μm, 200 μm, 100 μm; Or 80 μm, 50 μm, 30 μm; Or 20 μm, 10 μm, 5 μm.The channel depth of each three substrate chips is consistent, so that the batch production of the utility model three substrate chip.
The utility model technical characterstic is that chip manufacturing is convenient, simple to operate, professional stronger.
Compared with existing screening, the utility model has following beneficial effect: (1) can directly and automatic liquid adding device be used in conjunction, screen in liquid situation; (2) simple to operate, efficiency is high; (2) simply easy to make, save use cost.
