Fisherbrand™ accuCap™ Capillary Junction pH Combination Electrodes Glass Body, Fluid Gel, Refillable: Mercury-Free

Description

• Large junction for increased flow, minimal clogging Better junction Single-pore capillary junction is ∽200 times larger than typical ceramic junctions Almost impossible to clog, even in difficult samples Increased electrolyte flow, greater contact between sample and reference, fast and stable readings Better reference design Double junction design for enhanced performance Diffusion barrier separates silver chloride reservoir from reference electrolyte Permits use of silver-free electrolytes, prevents silver chloride loss from temperature-induced variations Result: an extremely stable reference potential, providing long electrode life Most accurate Testing at German Federal Physical Technical Institute in Braunschweig determined this electrode design to be the most accurate laboratory electrode See Traceability of pH measurement by Petra Spitzer; ISBN 3-89429-877-4 or SSN 0947-7063 Unique fluid-gel electrolyte and accuCap junction provide faster flowrate, improved contact between electrolyte and sample Faster response time and very accurate readings Double-liquid-junction further extends diffusion barrier for increased electrode life in aggressive samples Also performs well in liquids with low ion concentration and in partly aqueous samples
