Atomfair PTFE H-Type Replaceable-Membrane Photoelectrochemical Cell

Product Overview

The ATOMFAIR® PTFE H-Type Replaceable-Membrane Photoelectrochemical Cell features a PTFE body and is designed for three-electrode systems with volumes of 25mL and 40mL, with custom capacities available upon request. The cell is a semi-sealed system where the cathode chamber (working electrode) and anode chamber (counter electrode) are isolated by an ion-exchange membrane (user-supplied) with pin-sealed connections for easy membrane replacement. The working electrode and reference electrode are positioned in the same compartment to effectively reduce uncompensated resistance (iR drop). Sealing between the lid and cell body is achieved via a compression plate design. Electrode seals are achieved via compression fittings with O-rings on PTFE plugs. The cell includes a sub-surface sparger for gas purging (straight type for CO2 reduction, L-type for nitrogen reduction). Extended-length electrodes are required and must be ordered separately. An optical window can be added as a custom option upon request.

Performance Features

• Full PTFE construction: Excellent chemical resistance and inertness for aggressive electrolytes and harsh conditions.
• Two-compartment membrane separation: Isolates cathode and anode with user-supplied ion-exchange membrane for selective ion transport studies.

• Co-located working and reference electrodes: Minimizes uncompensated resistance (iR drop) for accurate measurements.

• Compression plate sealing: Provides reliable lid-to-body sealing for semi-sealed operation.
