Atomfair Sealed PTFE H-Type Replaceable-Membrane Photoelectrochemical Cell

Product Overview

The ATOMFAIR® Sealed PTFE H-Type Replaceable-Membrane Photoelectrochemical Cell features a PTFE body with an integrated quartz optical window (37mm diameter) that is removable and can be quickly replaced. The cell 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 an internal threaded design. Electrode seals are achieved via compression fittings with O-rings on the PTFE body. The cell includes a sub-surface sparger for gas purging. Extended-length electrodes are required and must be ordered separately.

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.

• Pin-sealed membrane connections: Facilitates quick and convenient membrane replacement.
