This is a special alkaline-resistant low volume PTFE cell kit that allows RDE/RRDE experiments to be conducted with as low as ~6-10 mL of electrolyte. It is compatible with all Pine Research rotators and RDE/RRDE tips. The 24/25 center port allows the RDE/RRDE tip, and four radially-spaced 14/20 ports allow reference and counter electrodes to be inserted with adapters. The kit comes with adapters and a counter electrode, but does not include a reference electrode. If working in strong alkaline electrolyte, the user may have two options. First, a standard size Hg/HgO Reference Electrode will fit in the side 14/20 ports, but is not available in LowProfile size. Alternatively, the user may purchase a LowProfile Ag/AgCl Reference Electrode that is not generally recommended for use with strong alkaline electrolyte, but may be used in limited cases with this cell design. Note that if using this Ag/AgCl reference electrode chemistry, it may be necessary to frequently discard and replace the reference electrode.

This low volume cell kit is ideal for low volume photoelectrochemical experiments where a window is needed to shine light onto an electrode surface. The cell can hold around 30 mL of electrolyte, and it is designed to accommodate three LowProfile electrodes (working, counter, and reference). The opening to the cell has an inner 24/12 taper joint and fits ideally with our Low Volume Cell Series Cap Kit.

The cell is fabricated from PTFE, and it is in a "flat cell" or Proteus cell style. This means the ends of the cell can be clamped with an optically-transparent quartz window (this kit includes 2 quartz disk windows and sealing o-rings), or a metal electrode sample if desired.

We have revised the standard sized platinum counter electrode. Previously, the shroud was constructed from an epoxy material. This material was not as resistant against non-aqueous solvents as desired; therefore, we now make the shroud from PTFE for superior chemical resistance in many applications. This electrode is commonly purchased as part of our counter electrode kit.
