Embodiment

[0027] Such as Figure 4 As shown, the electrode holder consists of an electrode holder 1, an electrode holder 2, a tightening screw 3, a nut 4 and a machine leg 5. The electrode holder 1 is square, and the middle is hollowed out to form a square ring-shaped frame. The four peripheries of the frame are respectively provided with grooves for embedding the electrode holder 2, the tightening screw 3 and the nut 4. The machine foot 5 is used to support the electrode holder 2. The electrode holder 2 is a rectangular parallelepiped with a circular hole hollowed out at a certain distance along the axial direction in the middle. The tightening screw 5 and the nut 4 are used to fasten the electrode holder on the electrode holder.

[0028] Such as figure 1 As shown, the electrode holder and the machine feet; the square ring frame of the electrode holder 1 is uniformly provided with 4 small holes with internal threads, and the small holes are screwed with a screw with a flat end at one end,...

Abstract

The invention provides an electrode bracket and applications thereof in a micro-fluidic chip system. The electrode mechanism comprises an electrode base, electrode brackets, shrinkage screws, nuts and pins. The middle part of the electrode base is hollowed, four edges are respectively provided with a groove, and the electrode brackets, the shrinkage screws and the nuts can be tightly embedded into the grooves. The pins are used for supporting the electrode base. The electrode bracket is a rectangle solid on which circular holes are hollowed at certain intervals. The electrode brackets are tightly fixed on the electrode base by the shrinkage screws and the nuts. When in use, the electrode bracket is arranged on a chip liquid storage groove, and the electrode brackets are fixed by the shrinkage screws and the nuts. The electrode is inserted into the hole of the electrode fame, and the fin height is adjusted so that the electrode is inserted into the chip liquid storage groove properly. The electrode bracket has simple use method, can be repetitively used for different chips, can fix the electrode in any point of the position in certain area, and is suitable for multiple-electrode fixing on complicated chips.

Description

Technical field [0001] The invention relates to a microfluidic chip system, in particular to an electrode support applied to the microfluidic chip system to support electrodes applied with voltage. Background technique [0002] In the early 1990s, Switzerland's Manz proposed a "miniature total analysis system" based on micro-electromechanical processing technology. It is expected that it will also play an important role in promoting the development of analytical science in the next 10 years. Micro total analysis system (microfluidic chip analysis system) is also called laboratory on a chip, which means that through the miniaturization and integration of chemical analysis equipment, the steps of sample processing, separation, and detection are integrated to maximize the analysis experiment The functions of the chamber are transferred to portable analysis equipment or even integrated on a chip. Due to its high integration and miniaturization, the microchip analysis system greatly ...
