[0002] In basic medicine, especially in the study of electrophysiology, microelectrodes, including glass, quartz microelectrodes or metal microelectrodes, are usually used to record the electrical activity of cells. There are two types of microelectrodes: one is a metal microelectrode, and the other is a glass microelectrode filled with an electrolyte solution. Metal microelectrodes are mostly made of 0.3-0.5 mm stainless steel wire or tungsten wire, which is processed by a special method. Except for the tip, the other parts of this electrode are insulated. Glass microelectrodes generally use hard capillary glass tubes with high melting point, high resistivity and low expansion coefficient. Pyrex capillary glass tubes are generally used abroad, and GG-17 capillary glass tubes are generally used in China, which are capillary glass tubes that have been purified.

In addition, the existing glass microelectrode device for injection is not easy to fix the syringe, the injection effect is poor, and the practicality is relatively strong. Utility Model Content
