Electroplating device of electrode for electrophysiological experiments

Abstract

The invention discloses an electroplating device of an electrode for electrophysiological experiments. An electroplating reactor contains at least an electroplating operating room which is composed of a sealed U-shaped tube. A silver filament to be electroplated passes through a central hole of a metal thin tube at one end of the U-shaped tube and then is immersed into an electroplate liquid to form an electroplating anode electrode. The other end of the U-shaped tube is provided with an electroplating cathode electrode and an opening and closing cover opening. A power supply controls the electroplating process through a control module which is composed of a circuit for keeping current constant and a circuit with a timing function. The electroplating operating room is also equipped with an electroplate-liquid level detector for liquid level of the electroplate liquid. By the adoption of a control circuit, current is controlled to be stable and electroplating time is controlled to be constant; it is ensured that thickness of silver chloride covering the surface of the silver filament electroplated each time is uniform and unified; and uncontrollable factors in an experiment are minimized. In addition, multiple electroplating tanks are also externally connected. Thus, high-flux electroplating is realized; multiple silver filaments can be electroplated at a time; and electroplating is more convenient, rapid and efficient.

Description

technical field [0001] The invention relates to an electroplating machine, in particular to an electroplating machine for electrode electroplating, which is applied in the technical field of electrophysiological experiment electrode coating preparation. Background technique [0002] Electrophysiological technology is a technical means to stimulate organisms with various forms of energy such as electricity and sound, and measure the power generation of organisms to study the electrical characteristics of organisms. Electrophysiological technique is one of the most commonly used techniques in neuroscience, mainly including patch clamp technique and two-electrode voltage clamp technique, both of which frequently use a thin silver wire coated with a layer of silver chloride as the Recording electrode and reference electrode. Electrodes must be prepared before each electrophysiological experiment, and sometimes electrodes need to be re-plated because the electrode coating falls ...

AI Technical Summary

Problems solved by technology

The traditional method is not only cumbersome to operate, pollutes the environment, and wastes materials, but also the effect is not very ideal: due to the unstable current, the electrode coating is uneven and easy to fall off; due to the uncontrollable time, the electrode thickness of each plating is not uniform, which interferes with the experiment

Another obvious disadvantage of the traditional electroplating method is that only one silver wire can be electroplated at a time, which is inefficient and far from meeting the needs of electrophysiological experiments.
