PTFE Test Cell (50mL) with Single Quartz Window for Fundamental Photoelectrochemistry (PEC) Research, CFPRPTFETC

A PTFE (Polytetrafluoroethylene) test cell with a quartz window is a specialized reactor designed for photoelectrochemical (PEC) research in aggressive environments. While glass is the standard for many labs, PTFE is chosen when the electrolyte would otherwise etch, contaminate, or react with a glass cell body.

There are many reasons to choose PTFE test cell for photoelectrochemistry research: (1) Chemical Inertness: PTFE is resistant to nearly all chemicals, including the concentrated bases (e.g., 6M KOH) used in alkaline water splitting and the aggressive organic solvents (Acetonitrile, DMF) used in CO2 reduction. (2) Purity: Unlike borosilicate glass, which can leach silicates and metallic impurities into the electrolyte at high pH, PTFE ensures that your measured photocurrent comes solely from your catalyst and not from background contamination. (3) Modular "Mini" Geometry: PTFE is easily machined into compact, gas-tight blocks. This allows for low-volume chambers that concentrate reaction products, making them easier to detect via GC or HPLC.
