Abstract

A chemical reaction vessel array used for electrochemistry related reaction and detection is characterized in that electrodes are arranged in each reaction vessel in the reaction vessel array and reaction in the reaction vessels can be respectively or simultaneously controlled or detected through external electric connection. The structure ensures that the electrodes in the reaction vessels can be controlled by only using few electrode lead wires.

Description

A kind of chemical reaction vessel array that has electrode

Technical field

A kind of chemical reaction vessel array that is used for galvanochemistry correlated response, detection.

Background technology

In every field such as bioanalysis, clinical detection, chemical analyses, electrochemical reaction and detection are a kind of application methods very widely.Conventional Electrochemical Detection adopts independently electrode and reaction tank usually, but in fields such as bioanalysis, clinical detection, chemical analyses, need to analyze and the sample size of reaction many, adopting independently, electrode and reaction tank can not well satisfy request for utilization.In above-mentioned every field,, adopt the plastic microporous plate to react, analyze and detect usually at present, on a smaller area, can carry out reaction, analysis and the detection of a large amount of samples like this in order to handle a large amount of samples.Electrochemical reaction and detection need electrode, usually external electrode needs to reuse, before the reacting hole in every detection microwell plate, all need to carry out complicated cleaning usually, can effectively avoid polluting and be equipped with independent electrode for each reacting hole to avoid pollution.Electrode is integrated on the microwell plate that extensively adopts at present, can further raises the efficiency and detection sensitivity, reduce the chance of cross pollution, be with a wide range of applications.

Summary of the invention

The objective of the invention is to propose a kind of multielectrode electrochemical array that has, the form based on microwell plate is of compact construction, and less extension line is user-friendly.Its people's advantage is to adopt less extension line just can the electrode in each reaction vessel to be powered up.

Of the present invention have multielectrode chemical array reaction vessel and be characterised in that: adopt a vessel array upper plate and an electrode plate be combined into that comprises electrode, lead-in wire and extension line, in conjunction with after, each container of vessel array all communicates with electrode plate in the bottom, and comprises column electrode and a row electrode at least one electrode plate.

Vessel array of the present invention comprises at least 2 row and 2 row containers, in fact, gets over for a long time when the ranks of container, and advantage of the present invention is outstanding more.

Electrode plate of the present invention, it is characterized in that: contain electrode and lead-in wire on it, electrode is in a side of electrode plate, its position is corresponding with each container of vessel array upper plate, every seniority among brothers and sisters electrode couples together by lead-in wire and is drawn by a public extension line, and every arrangement electrode couples together by lead-in wire and drawn by a public extension line.

Electrode is to be made of conductive material, may further include coating with certain function, film, molecule etc. on it, to realize corresponding chemical reaction and detection.

Electrode plate among the present invention, it is characterized in that: lead-in wire on it and extension line can be positioned at a side or the both sides of this base plate, when lead-in wire and extension line when being positioned at the both sides of base plate, can be by passing through electrode plate conductive via electrode, lead-in wire, the extension line connection of homonymy.

Electrode plate among the present invention is characterized in that: be made of non electrically conductive material.

Electrode among the present invention, lead-in wire and extension line is characterized in that: the material by conduction constitutes, and in the part that does not need to conduct electricity, can adopt nonconducting film, coating etc. to cover and protects.

Embodiment

The present invention is by a vessel array upper plate 1 and electrode plate 3 be combined intos.

The capable N row of the M of regular arrangement container 2 on the container upper plate 1, the bottom of each container is open, can combine with electrode plate like this.

Corresponding with vessel array upper plate 1, on the correspondence position of electrode plate 3, corresponding electrode is arranged, have a column electrode 4 and a row electrode 5 at least.Generally, if desired all electrodes are all drawn, then the entire container array needs extension line M * N * 2 piece, like this, for the more situation of sample size, for example, M=8, the situation of N=12, need this moment 192 extension lines to control to all electrodes, cause the reliability of total system to reduce like this, complicacy improves simultaneously, is difficult to accurate control reaction and testing result.

In the present invention, will link together by via hole 6 and lead-in wire 7 and column electrode extension line 8 with the column electrode 4 of delegation, the row electrode 5 with same row links together by via hole 6 and lead-in wire 7 and row electrode outlet line 9 simultaneously.When the electrode in the container of need be to A capable B row is switched on, only need power up and get final product at corresponding A column electrode extension line and B row electrode outlet line.The entire container array only needs M+N root extension line just can realize the electrode in each container in the entire container array is controlled like this.By said method, significantly reduced the quantity of extension line, improved reliability.

For an internal tank situation of two column electrodes is arranged, provided a design example of electrode plate as Fig. 4, increased a column electrode 4 ' in each container, increased column electrode extension line 8 ' accordingly simultaneously, needing extension line quantity altogether is M * 2+N.If do not adopt the present invention, then need M * N * 3.At 96 hole microwell plates commonly used (8 row * 12 row) design, the extension line number that above-mentioned two kinds of methods need is respectively 28 and 288, this shows that the present invention is very effective for reducing extension line.

Below in conjunction with the preferred embodiments to being described according to of the present invention.Parameter that those skilled in the art are appreciated that above to be mentioned such as quantity, size, and lead-in wire, electrode, the arrangement form of extension line via hole, the appellation of row and column etc. all are exemplary and should not be considered as limitation of the present invention.Scope of the present invention has the accompanying Claim book to limit.
