CHI134 Reference Electrode for Flow Cell
Brand: CH Instruments | Category: Nanotechnology
CHI134 is the reference electrode built for the CHI130 thin layer flow cell, with a polyacetal plastic body that CH Instruments describe as having good mechanical tolerance and chemical resistance. The centre wire is silver and the tip, 4 mm long and 3.4 mm in diameter, acts as the liquid junction through a VYCOR glass frit. The published specification states it is made for organic solvent and suits mild solvents such as acetonitrile, that the electrolyte may be changed for HPLC use, and that the plastic does not stand up to strong solvents such as THF.
