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

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
