{"product_id":"cfpr5psqc","title":"Five-Port Square Quartz Cell (L30*W30*H40 mm) for Fundamental Photoelectrochemistry (PEC) Research, CFPR5PSQC","description":"\u003cp\u003eA five-port square quartz cell is a specialized reactor designed for fundamental photoelectrochemistry (PEC). Unlike standard cylindrical glass cells, the square geometry and quartz material are specifically chosen to minimize optical distortions and allow for the transmission of high-energy ultraviolet (UV) light, which is essential for activating wide-bandgap semiconductors like TiO2.The five-port configuration provides the necessary ports for a standard three-electrode system while allowing for rigorous environmental control (gas purging) required for sensitive solar-fuel research.\u003c\/p\u003e\n\u003cp\u003eThe reasons choose the square quartz are shown below: (1) \u003cstrong\u003eOptical Precision\u003c\/strong\u003e: Cylindrical glass acts like a lens, refracting and focusing light inconsistently across the electrode surface. A flat, square quartz face ensures that the incident light (from a solar simulator or laser) hits the photoelectrode at a perpendicular angle with uniform intensity. (2) \u003cstrong\u003eUV Transmission\u003c\/strong\u003e: Standard borosilicate glass blocks light below ~300 nm. Quartz (specifically High-Purity Synthetic Fused Silica) is transparent down to 170–200 nm, allowing for the study of UV-active photocatalysts. (3) \u003cstrong\u003eLow Fluorescence\u003c\/strong\u003e: Quartz has negligible background fluorescence compared to glass, which is critical if you are combining electrochemical measurements with operando fluorescence spectroscopy.\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\u003eCFPR5PSQC (C-FPR-5PSQC)\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 square 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. \u003c\/li\u003e\n\u003cli\u003eThe maximum operation temperature can be up to 900 °C. \u003c\/li\u003e\n\u003cli\u003eThe cell lid is PTFE with five ports.
