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
