Complete Spectroelectrochemistry Cell Kit: The Honeycomb Spectroelectrochemical Cell Kit (AKSTCKIT3) includes 1 quartz cuvette, 1 cell cap, 1 platinum honeycomb electrode, 2 gold honeycomb electrodes, the Universal Specialty Cell Connection Kit, and a low profile Ag/AgCl reference electrode. Our honeycomb electrode chip contains an onboard working, counter and reference electrode. If an alternative reference electrode is needed, we offer a cell cable with a separate reference breakout lead (RRTPE05 for the WaveNow Series and ACP2E09 for the WaveDriver series) used with the WaveNow and WaveDriver respectively where a separate low profile reference electrode fits into the cell cap.

Electrode Design: The working electrode is perforated with a honeycomb pattern of holes which allow light to pass through the electrode. The active surface of the working electrode includes a metal coating along the inner walls of the holes. As light passes through the holes, the beam grazes the walls of each hole. Normally the path length of the electrochemically generated species is the diffusion layer near the surface of the electrode. With our honeycomb design the effective path length is the length of the honeycomb card (1.7 mm). As a result, molecules with low extinction coefficients are more easily detectable. Our quartz cuvette is slotted to fit the honeycomb electrode card. The slot also prevents electrogenerated species from diffusing away from the electrode during a spectroelectrochemistry experiment, further improving UV/Vis absorbance.
Universal Compatibility: The honeycomb electrode is screen printed on a ceramic card, allowing it to be used for both aqueous and non-aqueous solvents. The dimensions of our slotted quartz cuvette is 12.5 x 12.5 x 45.0 mm3, which is the standard size for most UV/Vis spectrometer cuvette holders. While Pine Research offers a unique cable that connects the mini-B USB of the honeycomb cell to our WaveNow and WaveDriver potentiostats, we also include a Universal Specialty Cell Connection kit with each Honeycomb cell, for use with any potentiostat.
