{"product_id":"cfprrqc","title":"Round Quartz Cell (O.D.= 25mm, I.D. = 20 mm, H=40 mm) for Fundamental Photoelectrochemistry (PEC) Research, CFPRRQC","description":"\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eThe reasons choose the round quartz are shown below: (1) \u003cstrong\u003eStructural Integrity\u003c\/strong\u003e: 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) \u003cstrong\u003eUniform Mixing\u003c\/strong\u003e: 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) \u003cstrong\u003eUV-Transparency\u003c\/strong\u003e: Quartz (Fused Silica) provides \u0026gt;90% transmission for wavelengths as low as 200 nm, which is necessary for wide-bandgap photocatalysts that do not respond to visible light.\u003c\/p\u003e\n\u003cp\u003eThe five-port configuration can be used to host the working, counter, and reference electrode, as well as gas inlet and outlet.\u003c\/p\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eCFPRRQC (C-FPR-RQC)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eCell Features\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cul\u003e\n\u003cli\u003eThe round electrochemical cell body is made of quartz that has high light transparence (\u0026gt;95%) \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe quartz cell was made in integrated molding. \u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe cell lid is PTFE with five ports.
