C009 spherical corrosion test cell

1. The electrolytic cell has an adjustable angle salt bridge (Lukin capillary) so that the reference electrode can be aligned with the corrosion sample by adjusting the angle, and the R drop can be reduced more effectively.

2. The electrolytic cell is used as a corrosion laboratory to avoid chloride ions, so the solution filled in the salt bridge is a saturated potassium nitrate solution.

3. The working electrode of the electrolytic cell is equipped with a sample support electrode, which can be replaced according to your own requirements. The sample diameter is 14mm and the fixed area is 1 square centimeter.

4. Configuration: electrolytic cell body, F-type air inlet, salt bridge, liquid seal, polytetrafluoroethylene stopper, sample support reference electrode, graphite rod electrode.

5. The cell body material of the electrolytic cell is high borosilicate glass

6. The electrolytic cell is a relatively sealed electrolytic cell system, which is often used in a three-electrode system. The usual volume of the electrolytic cell is 500ml and 1000ml, and it can also be customized according to requirements.

7. The glass part of the electrolytic cell adopts a frosted mouth and is matched with an inverted cone-shaped PTFE lid to seal the cell and lid.

8. The sealing of the electrode part of the electrolytic cell is realized on the PTFE plug, and the sealing effect is achieved by squeezing the O ring by the sealing screw

9. This electrolytic cell is equipped with F-type air inlet that can ventilate up and down the liquid surface. The atmosphere is protected according to the experiment. When the experiment starts, please stop the ventilation under the liquid surface and only keep the ventilation on the liquid surface.

10. The electrolytic cell is divided into two forms: single-layer and double-layer. The double-layer has the function of a constant temperature water bath on the basis of the single layer. The circulating constant temperature water is continuously passed into the jacket layer of the electrolytic cell to make the inside of the electrolytic cell The test solution reaches a constant temperature effect. If you need to add a thermometer to read the temperature of the double-layer electrolytic cell, you need to add a port on the top of the electrolytic cell body so that the five-port cell becomes a six-port cell. At this time, additional costs are required.

11. Electrolytic cell cover material: PTFE, the size of the cover varies according to the volume of the electrolytic cell.

12. Scope of application: It can be used to test and determine metal samples in corrosive environments. It can ensure rapid and consistent testing of a group of metal samples in a liquid environment. It is suitable for most electrochemical instruments used for corrosion tests. Use in a sexual environment (except HF), room temperature and high temperature.
