The primary objective of these designs is outlined in "3D Printed UV-vis Cuvette Adapter for Low Cost and Versatile Spectroscopic Experiments," which is published in the open-access journal ACS Omega. Reference: http://pubs.acs.org/doi/abs/10.1021/acsomega.7b01310 This specific component aims to replicate traditional quartz and glass UV-vis spectrometer cuvettes. In this design, we have a path length of 10 mm. This adapter is designed to hold a planar and transparent working electrode such as ITO or FTO. A reference electrode can be placed in the adjacent hole, while the counter electrode is situated in the second hole. Note that the counter electrode hole connects to the main electrolyte compartment via an underground tunnel. A peltier-thermoelectric module (with a hole) can be used to control temperature (https://tetech.com/peltier-thermoelectric-cooler-modules/round-with-center-hole/). Furthermore, there is a protected inlet port allowing for the electrolyte to be flushed with gas without generating intense bubbles at the electrode surface. This cuvette can be utilized in most research-grade UV-Vis spectrometers. We recommend printing this design using black filament to minimize light scattering. An instructional video demonstrating assembly of the spectrometer is shown below (post-printing) along with materials used. Either quartz or glass windows can be employed depending on the spectral range required for the cuvette.
