Reference Electrodes

These compact, glass-bodied reference electrodes from BASi are available in two styles. The 7.5 cm long RE-5B reference electrode is used for electrochemistry experiments and is compatible with the C-3 Cell Stand, the CGME Controlled Growth Mercury Electrode Cell Stand, and the RDE-2 Rotating Disk Electrode Cell Stand. The RE-6 and RE-4 reference electrodes (3 cm) are designed for use with BASi Electrochemical Flow Cells. All electrodes have a 6 mm OD glass body, and use a porous junction (frit) made from a ceramic material (for the RE-6 and RE-4) or CoralPor™ (for the RE-5B, part number MF-2064). (Please note that due to the high resistance of the ceramic frit, the RE-6 and RE-4 electrodes are 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 (for the RE-5B and RE-6). An O-ring is included with each electrode. Between uses, reference electrodes should be stored with junction tips in a MR-5275 vial filled with the appropriate storage solution (CF-3000 or CF-3001).

The MF-2030 double junction reference electrode can be set up using an RE-5B reference electrode with the glass chamber . This chamber also has a CoralPor™ frit, which must be maintained.
