Ideal for researchers working with constrained sample volumes, non-standard electrochemistry hardware, or where traditional 6.0 mm probes cannot fit. Available in both aqueous (Ag\/AgCl) and non-aqueous (Ag\/Ag⁺) configurations, they provide the same trusted electrochemical stability as our standard range of reference electrodes in a compact form factor.\u003c\/p\u003e\n\u003cp\u003eProper storage is recommended.  To avoid ruining the internal solution and clogging the junction, avoid drying out your electrodes. To protect essential ions and maintain accurate readings, avoid storing or rinsing in pure deionized or distilled water. Cap the filling holes to prevent evaporation, and keep away from extreme temperatures to prevent cracking or crystallization.\u003c\/p\u003e\n\u003cdiv class=\"info-tip-box\"\u003e\n\u003cp\u003eThese electrodes feature a narrow 2.3 mm or 4.0 mm outer diameter shaft.
