Catalog No. 13-620-131



Description

Description

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

  • Standard glass body and pH membrane
  • Solid polymer-gel electrolyte offers the advantages of the accuCap system in a maintenance-free version
  • Provides a more stable matrix than other gelled electrode reference systems
  • Gives reliable results in very dirty, ion-weak or protein samples
  • Reliable even at low pH or in presence of organic solvents
