Product Description
PTFE H-type Optical Electrochemical Cell
Sealed Configuration · Quartz Optical Window · Replaceable Ion-Exchange Membrane
Product Overview
The PTFE H-type Optical Electrochemical Cell is a fully sealed, dual-chamber electrochemical reactor designed for photoelectrochemistry, spectroelectrochemical analysis, and gas-involved electrochemical reactions.
Constructed with chemically inert PTFE cell bodies and high-transmittance quartz optical windows, this system enables simultaneous electrochemical control and in-situ optical access under strictly sealed conditions.
A replaceable ion-exchange membrane (PEM / AEM / diaphragm) is clamped between the two chambers, allowing controlled ionic transport while maintaining physical separation of anodic and cathodic compartments.
This model is supplied only in sealed configuration, ensuring excellent gas-tightness and reproducibility.
Cell Configuration
H-type dual-chamber design (sealed)
•Left chamber: working electrode compartment
•Right chamber: counter / reference electrode compartment
•Central membrane interface: replaceable ion-exchange membrane
•Side-mounted quartz optical window for in-situ illumination and spectroscopy
✔ Designed for closed-system experiments, gas control, and optical measurements ✔ Not available in non-sealed version
