(RE 803 Ag/AgCl, 3M Cl-)

Electrode Design

The RE 803 is fabricated from chloridized, high-purity silver wire immersed in a contacting solution of 3M potassium chloride that is saturated with silver chloride. The electrode is a compact 6 cm long with a narrow 2.5 mm O.D. glass barrel. Two glass barrels are provided. The first has a fine 1.0 mm O.D. glass fiber tip and the second has a fine 2.0 mm O.D. tip of a fritted ceramic. Each barrel has a 10 mL electrolyte capacity and a very slow 1.7 mL/day flow rate (glass fiber tip) and 5 mL/day flow rate (fritted tip). Electrodes are outfitted with U.S. Standard pin-type connectors and each is supplied with 25 mL filling solution, a filling capillary, and an instruction sheet.
