Reference Electrodes

Feature

  • For application in an aqueous solution
  • Relatively long life time

  • RE-1B
  • RE-1S
  • RE-1CP
  • RE-3VT

RE-1B Reference electrode (Ag/AgCl)

3M NaCl is used as an internal solution.
This is the standard type of aqueous reference electrode.

RE-1B Reference electrode (Ag/AgCl)
Reference potential
AgCl+e=Ag++Cl-
E0=195 mV vs RHEK (25℃)
∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013373).


RE-1S Reference electrode (Ag/AgCl)

Small size for the standard type (RE-1B).

RE-1S Reference electrode (Ag/AgCl)
Reference potential
AgCl+e=Ag++Cl-
E0=195 mV vs RHEK (25℃)
∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013373).


RE-1CP Reference electrode (Ag/AgCl/Saturated KCl)

Aqueous reference electrode with a saturated KCl as an internal solution.

RE-1CP Reference electrode (Ag/AgCl/Saturated KCl)
Reference potential
AgCl+e=Ag++Cl-
E0=198 mV vs RHEK (25℃)
∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013373).


  • Material: Polymethylpentene is used, because of the excellent chemical resistance characteristics.
  • Liquid junction: Ceramics is used. (∗If you keep the electrode immersed in an alkaline solution for a long time, life time will be shortened.)

RE-3VT Reference electrode screw type (Ag/AgCl)

Aqueous reference electrode specific for ALS line-up flow cell, as Cross flow cell, Radial flow cell, EQCM flow cell and SEC-2F Spectroelectrochemical flow cell.

RE-3VT Reference electrode screw type (Ag/AgCl)
Reference potential
AgCl+e=Ag++Cl-
E0=195 mV vs RHEK (25℃)
∗ The reference potential is the measured value using RHEK reversible hydrogen electrode kit (Cat. No. 013373).


For the screw type electrode, the body in PEEK material is also available.

013503 RE-1CP Reference electrode (Ag/AgCl/Saturated KCl) Ceramics saturated KCl Polymethyl pentene SVC-2, SVC-3, VC-4, Bulk electrolysis, RRDE, EQCM
013488 RE-3VT Reference electrode screw type (Ag/AgCl) Ceramics 3 M NaCl Polymethyl pentene Flow cell (LC, EQCM, SEC-2F)

∗ IPPG: Ion Permeability Porous Glass

∗ Keep the reference electrode in a cold dark place.
∗ Take care when you open and unseal the electrode. The liquid junction tip could be taken out when you pull the black protector.
∗ RE-3VT is specific for ALS line-up flow cell, it could be incompatible with other brand flow cell.
