A porous interface in reference electrodes that allows ionic contact while preventing solution mixing.
The liquid junction is a critical component in reference electrodes that creates a controlled ionic pathway between the internal filling solution and the external sample solution. It maintains electrical continuity while minimizing contamination and diffusion between solutions, ensuring stable reference potential measurements in pH meters, ion-selective electrodes, and other electrochemical systems.

这些分值是采购评估维度示例，不代表真实客户评分、具体国家买家反馈或实时询盘。
Junction potential errors occur when different ionic mobilities create voltage differences at the interface. Proper junction design and electrolyte selection minimize these effects.
Regular maintenance depends on usage: clean monthly for routine applications, replace annually, or immediately if clogging or unstable readings occur.
Specialized junctions with PTFE or ceramic materials are required for organic solvents, as standard junctions may degrade or clog.
