Conventional electrochemical cells include ordinary electrolytic cells, sealed electrolytic cells, traditional five-port electrolytic cells, and PTFE electrolytic cells. Ordinary electrolytic cells are generally used for basic teaching demonstrations or entry-level electrochemical tests. The entire system is not sealed, but is directly composed of working electrodes, counter electrodes, and reference electrodes, and is tested with a potentiostat.

The ordinary electrolytic cell is composed of a high borosilicate glass cell body and a PTFE cover. Three ordinary holes for electrodes are conventionally opened on the cover, and the electrodes are fixed and placed with fluorine rubber O-rings.If there is space on the cover, it will also be equipped with two small holes for inserting the PTFE tube for gas transmission. The solid T-type Teflon plug included in the accessory can also block the unused gas hole. Square holes can also be customized according to customer requirements or drawings. The lower glass tank body can also be customized into a double-jacketed glass type according to the temperature control requirements. It is connected to the outer tank body through the hose of a peristaltic pump or a circulating pump. The liquid circulates in the glass jacket layer.Relying on the exchange of cold and heat to achieve the effect of cooling or heating the electrolyte solution.

The volume of the electrolytic cell should be selected moderately. If the volume is too large, the amount of solution will be too much, which is unnecessary. During electrochemical measurement, the electrode surface undergoes oxidation and reduction reactions, and some substances in the solution are reduced by participating in the electrode reaction. At the same time, some reaction products will dissolve into the solution. If the volume of the electrolytic cell is too small, the solution concentration will change significantly during the long-term steady-state measurement, which will eventually affect the experimental results. In most cases, the volume of 50ml and 100ml are more choices. When the sample is large or more electrodes need to be inserted, larger volumes including 150ml, 200ml, 300ml and 500ml will also be frequently used.

The material of the electrolytic cell must have good stability. In general, high borosilicate glass is widely used to make electrolytic cells of various shapes because of its good chemical stability, wide use temperature, high transparency and processing performance. The electrolytic cell made of glass is very stable in most inorganic electrolyte solutions and organic electrolyte solutions. At the same time, considering the use requirements of some special electrolyte systems and special shapes, PTFE, plexiglass, PEEK materials and various types of metal materials can also be used as preparation materials for electrolytic cells.
