Choice of Ag/AgCl Single- or Double-Junction internal reference elements

  • Single-junction models with Ag/AgCl reference are perfect for routine pH and titration measurements of aqueous solutions with small samples, small vessels
  • Double-junction models with Ag/AgCl reference are useful in aqueous and nonaqueous solutions, and in applications requiring TRIS buffers

  • For aqueous and nonaqueous samples
  • Double-junction Ag/AgCl eliminate measurement and clogging problems when used in research with Tris buffers
