Porous ceramic wick for PH ELECTRODE

POROUS CERAMIC ROD FOR pH ELECTRODE

As the core component of the salt bridge/liquid junction in pH combination electrodes and reference electrodes, the porous ceramic wick undertakes the key functions of electrolyte permeation, stable liquid-junction potential, and isolation of contaminated media. It directly determines the electrode's measurement accuracy, response speed, and service life.
Depending on the glass material used, there are alumina and zirconia ceramic wicks (with different expansion coefficients), which match the glass material and avoid cracking during welding.



Key Features

- Excellent Corrosion Resistance & Long Service Life
Made of high-purity alumina/zirconia, it withstands strong acids, strong alkalis, high temperatures, high chlorine, oil-containing/protein-containing media, without dissolution or sample contamination, ensuring a long service life.
- Precise Porous Structure & Stable Flow Rate
With sub-micron level uniform pores, the electrolyte permeates evenly, ensuring stable liquid-junction potential, good reproducibility, and drift-free readings.
- High Temperature Resistance & Adaptable to Harsh Conditions
Resistant to temperatures from -100℃ to 100℃, suitable for online monitoring in fermentation, pharmaceutical, and high-temperature chemical processes.
- Wide Compatibility & Stable Performance
Compatible with various pH combination electrodes and reference electrodes. Multiple specifications are available and customizable, with stable batch consistency and adaptability to electrode production volumes.
