H-Type PTFE Test Cell (25mL+25mL) with Single/Double Quartz Window for Fundamental Photoelectrochemistry (PEC) Research, CFPRHTPTFETC

An H-type PTFE Testing Cell with a Quartz Window is the pinnacle of reactor design for researchers working in harsh electrochemical environments. While glass H-cells are common, the PTFE (Teflon) body is explicitly required when working with highly alkaline solutions (like 6M KOH for Zinc-Air or water splitting) or aggressive organic solvents that would otherwise leach impurities from, or etch, a glass surface.

The H-type geometry provides physical separation between the anode and cathode, while the PTFE construction ensures that the cell itself remains a passive participant in the reaction. (1) Chemical Superiority: PTFE is nearly universally inert. This is critical for N2 reduction (NRR) or CO2 reduction (CO2RR) research, where trace silicates or metal ions leached from glass can lead to "false positive" catalytic activity. (2) Quartz Window (JGS1/JGS2): To allow light in, a flat quartz disk is compression-sealed into the side of the PTFE chamber. This provides >90% transmission for UV-Vis light, allowing you to illuminate your photoelectrode (FTO/ITO) without the "lensing effect" caused by curved cell walls. (3) Durability: Unlike quartz square cells, a machined PTFE block is virtually indestructible and can withstand accidental drops or high-torque clamping of membranes.
