PTFE Non-Sealed Electrolytic Cell with Quartz Optical Window

Product Overview

The FrankLab PTFE Electrolytic Cell with Quartz Optical Window is a chemically inert electrochemical reactor designed for optical electrochemistry, photo-electrochemical studies, and corrosive electrolyte systems where conventional glass cells are not suitable.

The cell body is machined from high-purity PTFE, combined with a quartz optical window that provides excellent UV–Vis light transmission while maintaining chemical resistance and structural stability.

Two configurations are available to match different experimental needs:

•PTFE Non-Sealed Electrolytic Cell – open system for routine optical electrochemistry

•PTFE Sealed Electrolytic Cell – gas-tight system for controlled atmosphere experiments

Product Versions

1. PTFE Non-Sealed Electrolytic Cell (Quartz Optical Window)

Designed for routine laboratory electrochemical and optical measurements under ambient conditions.

Key characteristics:

•Open, non-sealed structure

•Easy electrode insertion and adjustment

•Rapid electrolyte replacement

•Optical access through quartz window

✔ Best choice for UV-Vis monitoring, photo-electrochemistry, and method development

2. PTFE Sealed Electrolytic Cell (Quartz Optical Window)

Designed for experiments requiring gas isolation, controlled atmospheres, or volatile electrolytes.

Additional features:

•Gas-tight PTFE sealing system

•Dedicated gas inlet and outlet ports

•Reduced oxygen / moisture interference

•Stable optical path during long-term testing

✔ Best choice for CO₂RR, air-sensitive reactions, operando optical studies

Available Volumes

Both versions are available in the following working volumes:

•50 mL

•100 mL

•150 mL

•200 mL

•300 mL

•500 mL

Custom volumes and asymmetric designs are available upon request.

Key Features

• Quartz Optical Window for In-Situ Monitoring

The integrated quartz window enables real-time optical observation of electrochemical processes without disturbing the electrode configuration.

Supports:

•UV-Vis absorption

•Photo-electrochemical reactions

•Optical tracking of intermediates

• PTFE Construction for Maximum Chemical Compatibility

PTFE provides exceptional resistance to:

•Strong acids (H₂SO₄, HCl, HNO₃)

•Strong bases (KOH, NaOH)

•Organic solvents

✔ Ideal for aggressive or non-standard electrolytes

• Flexible Electrode Configuration

Compatible with:

•Glassy carbon, Pt, Au, metal rod electrodes

•Wire or plate counter electrodes

•Standard reference electrodes (Ag/AgCl, Hg/HgO, SCE)

Electrode port size and threading can be customized.

• Sealed or Open — Choose Your Workflow

•Non-Sealed: fast operation, high flexibility

•Sealed: controlled gas environment, improved reproducibility

Both versions share identical optical geometry.

Typical Applications

•Photo-electrochemical (PEC) experiments

•Optical electrochemistry (UV-Vis coupling)

•CO₂ electroreduction (sealed version)

•Corrosive electrolyte systems

•Catalyst screening under illumination

•Mechanistic electrochemical studies
