Problems solved by technology

It is very important to realize the connection between the external fluid and the microfluidic chip. There must be an interface in the middle. At present, there are literature reports or the company’s publicity that the pressure resistance of the interface is not good (mainly the sealing method and material, mostly normal pressure , rarely more than 20KG), inconvenient to operate
It hinders the application and development of microfluidic chip work

Embodiment Construction

[0017] Connecting screw 6 is a PEEK connector (product model: Upchurch company, Ftg NT, PEEKHex-Head, 1 / 16),

[0018] Such as figure 1 As shown, a combined state of the general-purpose microfluidic chip fixture is shown. The combined fixture of the present invention consists of a fixture B plate, a chip, a polyvinyl fluoride blade ring, an M3 screw, a fixture A plate, connecting screws, a sleeve, a glass capillary, etc. composition;

[0019] The axial cross-section of the upper half of the inlet or outlet of the liquid storage tank on the chip is an inverted trapezoidal shape, and the axial cross-section of the lower half is rectangular. There are 10 M3 fixing screw holes and 12 Observation holes, there are 10 holes on fixture A plate corresponding to the M3 fixing screw holes on fixture B plate 12 holes of 3 / 16"N=32 and 12 on fixture B plate Observe the screw hole corresponding to the hole.

[0020] The fixture A plate is an inverted groove with a rectangular groove o...

Abstract

The invention relates to a universal microfluidic chip fixture. The universal microfluidic chip fixture is composed of a fixture B plate, a chip, a polyvinyl fluoride blade ring, a screw, a fixture A plate, a connecting screw, a sleeve and a glass capillary. The universal microfluidic chip fixture has the advantages that a V-shaped hole is adopted by the chip; the connecting screw presses the glass capillary tightly through the polyvinyl fluoride blade ring; sealing property is good; and operations are convenient. By adopting 3/16''N=32 standard screw, the fixture is convenient and economic. Two sides of the fixture A plate are cut apart, so that the chip can be assembled and disassembled conveniently; and the fixture B plate is provided with twelve [phi]4 observation wells, thereby facilitating observation of assembly conditions.

Description

Technical field: [0001] The invention relates to the application technology of a microfluidic chip, and in particular provides a connection interface specially used for externally connecting a fluid to the microfluidic chip. Background technique: [0002] Micro Total Analysis Systems (μ-TAS) is a new interdisciplinary field, the ultimate goal of which is to maximize the transfer of analytical laboratory functions to portable analytical instruments through the miniaturization and integration of chemical equipment. In the equipment (such as various chips), the "miniaturization" of the analysis equipment is realized, so the micro-analysis system is also popularly called "Lab-on-a-chip". According to the chip structure and working mechanism It can be divided into two categories: Microarray chip (Microarray chip), also known as "biological chip", and microfluidic chip (Microfluidic chip). The former is quite mature and has been deeply industrialized abroad; the latter is mainly ...
