Round Quartz Cell (O.D.= 25mm, I.D. = 20 mm, H=40 mm) for Fundamental Photoelectrochemistry (PEC) Research, CFPRRQC

A five-port round quartz cell is a specialized electrochemical reactor used for photoelectrochemical (PEC) research where high-intensity light exposure is required. While square cells are often preferred for their lack of distortion, the round (cylindrical) quartz cell is the standard for high-volume testing, high-temperature experiments, and setups requiring a perfectly uniform thermal environment. The use of quartz ensures that UV light (critical for semiconductors like TiO2 or ZnO) reaches the sample without being filtered out by standard laboratory glass.

The reasons choose the round quartz are shown below: (1) Structural Integrity: Cylindrical geometries handle internal pressure and thermal expansion better than square cells. If you are conducting PEC at elevated temperatures, a round cell is less likely to crack. (2) Uniform Mixing: The circular base is optimized for magnetic stirring, creating a vortex that ensures reactants (like dissolved CO2) are uniformly distributed and that gas bubbles (H2 or O2) are swept away from the light path. (3) UV-Transparency: Quartz (Fused Silica) provides >90% transmission for wavelengths as low as 200 nm, which is necessary for wide-bandgap photocatalysts that do not respond to visible light.

The five-port configuration can be used to host the working, counter, and reference electrode, as well as gas inlet and outlet.
