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.

CHI135 is the 25 mm spacer CH Instruments publish for the CHI130 thin layer flow cell. It is the only accessory in this group listed in packs, the published unit being four per pack.
Platinum is the working surface of this flow cell electrode, listed as CHI133 for the CHI130 thin layer flow cell. CH Instruments offer it alongside the CHI131 glassy carbon and CHI132 gold electrodes for the same cell.
CHI140A is the spectroelectrochemical cell kit in the CH Instruments range, built around a thin layer quartz glass cell. The published kit sheet lists a platinum gauze working electrode, a platinum counter electrode, a Teflon cap and a 10 cm ETFE purge tube alongside the cell body. No reference electrode is included: CH Instruments name 012167 for aqueous Ag/AgCl work and 012171 for non-aqueous Ag/Ag+ work as the options.
