Spectroelectrochemical Cell with Temp and Gas Control

The general purpose of these designs are described in "3D Printed UV-vis Cuvette Adapter for Low Cost and Versatile Spectroscopic Experiments", which is published in the open access journal ACS Omega. Link to publication:http://pubs.acs.org/doi/abs/10.1021/acsomega.7b01310 This particular part is designed to mimic traditional quartz and glass UV-vis spectrometer cuvettes with a path length of 10 mm. It holds a planar and transparent working electrode, such as ITO or FTO, in place. A reference electrode can be placed in the adjacent hole and the counter electrode in the second hole. The counter electrode hole is connected to the main electrolyte compartment via a tunnel running underneath. A peltier-thermoelectric module with a hole can be used to control temperature (https://tetech.com/peltier-thermoelectric-cooler-modules/round-with-center-hole/). Additionally, there's a protected inlet port for flushing the electrolyte with gas without generating intense bubbles at the electrode surface. This cuvette can be used in most research-grade UV-Vis spectrometers. Printing it with black filament reduces light scattering. An instructional video to assemble the spectrometer is shown below (post-printing) along with materials used. Either quartz or glass windows can be chosen based on the spectral range needed of the cuvette.
