Description
The R0302 Ag/AgCl reference electrode is an essential tool for high-precision electrochemical analysis. Designed for durability and stability, it utilizes a glass body construction with a refillable internal chamber, allowing researchers to maintain the electrolyte concentration (3.5M KCl) for long-term consistency.
The integration of a porous Teflon (PTFE) frit as the liquid junction ensures a uniform and low leakage rate, which is critical for preventing contamination of the test solution while maintaining a stable electrical connection. Its standard 6mm outer diameter ensures seamless compatibility with most commercial electrochemical workstations and laboratory-scale testing hardware.
Features
- High Potential Stability: Delivers a consistent and reproducible reference potential with minimal drift over time.
- Refillable Design: Features a top sealing port for easy replenishment of the 3.5M KCl internal electrolyte, extending the electrode’s lifespan.
- Chemical-Resistant Junction: The porous Teflon (PTFE) frit provides excellent chemical resistance and prevents clogging compared to traditional ceramic junctions.
- Universal Compatibility: Designed with a standard 6mm OD to fit CHI, Metrohm, Autolab, and other major electrochemical workstation cell holders.

Reference Electrode Potential Selection Guide
| Reference Electrode Name | Electrode Structure | Potential (V vs. SHE) | Common Applications | Pros & Cons |
| Saturated Calomel Electrode (SCE) | Hg/Hg2Cl2/Saturated KCl | 0.242V | Neutral, Acidic | Recommended for use below 40°C; cannot be used in alkaline environments. |
| Silver/Silver Chloride Electrode (Ag/AgCl) | Ag/AgCl/3.5M KCl | 0.205V | Neutral, Acidic | Excellent stability. Avoid use with HNO3 or ions such as Br-, I-, NH4+, and CN-. |
| Mercury/Mercuric Oxide Electrode (Hg/HgO) | Hg/HgO/1M KOH | 0.098V | Alkaline | High sensitivity and fast response. Recommended for use below 40°C. |
| Mercury/Mercurous Sulfate Electrode (Hg/Hg2SO4) | Hg/Hg2SO4/Sat. K2SO4 | 0.656V | Sulfuric acid & Sulfate solutions | Use below 40°C. Note: High negative temperature coefficient and thermal hysteresis. |
| Non-Aqueous Silver Ion Electrode (Ag/Ag+) | User-prepared | - | Non-aqueous / Organic systems | Potential depends on the specific organic electrolyte and Ag+ concentration used. |
