Fused Quartz Sealed Optical Electrochemical Cell

Product Overview

The FrankLab Fused Quartz Sealed Optical Electrochemical Cell (50 × 50 × 50 mm) is a fully enclosed, multi-port electrochemical reactor designed for optical, spectroelectrochemical, and gas-controlled electrochemical experiments.

Constructed entirely from high-purity fused quartz, this cell provides excellent optical transparency, chemical resistance, and thermal stability, making it ideal for experiments involving UV–Vis spectroscopy, photoelectrochemistry, gas–liquid electrochemistry, and sealed electrolysis.

The square geometry ensures uniform optical path length and stable electrode positioning, while the PTFE sealing system enables airtight operation for volatile, air-sensitive, or gas-involved reactions.
