Reference Electrodes

Silver/Silver Chloride (Ag/AgCl) Reference Electrodes from BAS Inc.

These compact, glass-bodied reference electrodes are available in two styles. The 7.5 cm long RE-5B reference electrode (3 M NaCl or 3 M KCl fill available) is used for voltammetry and polarography experiments using the  C-3 Cell Stand, the CGME Controlled Growth Mercury Electrode, the RDE-1 and RDE-2 Rotating Disk Electrodes, and the LCM Low Current Module. The RE-6 reference electrode (3 cm) is used with the CC-5 Cross-Flow Thin-Layer Flow Cell. The RE-4 is also 3 cm long. All electrodes have a 6 mm OD glass body, and use a porous junction (frit) made from either ceramic (RE-4, RE-6) or CoralPor™ (RE-5B). (Note that, due to the high resistance of the ceramic frit, the RE-6 electrode is only recommended for aqueous electrolytes.)

Connection to the cell lead is via a gold-plated pin on the end of a flexible plastic-coated wire (RE-5B and RE-6) or stainless steel pin (RE-4). An O-ring is included with each electrode. Between uses, reference electrodes should be stored with junction tips in a MF-5275 vial filled with 3 M NaCl. A double junction reference electrode can be set up using an RE-5B reference electrode with the glass chamber MF-2030. This chamber also has a CoralPor™ frit, which must be maintained.

Non-Aqueous Silver/Silver Ion (Ag/Ag+) Reference Electrode Kit

MF-2062 Non-Aqueous Reference Electrode Kit***

This kit contains the parts required for construction of a non-aqueous silver/silver ion reference electrode. The glass electrode body has a porous CoralPor™ tip attached with heat shrink tubing. The removable Teflon top contains a silver wire and 0.060 ” gold-plated connecting pin for the cell lead. The kit also contains solid silver nitrate, extra heat shrink tubing, and extra porous CoralPor™ tips. Non-aqueous solvents must be supplied by the user. An instruction sheet illustrates easy assembly.
