PTFE Non-Sealed Electrochemical Cell

Product Overview

The FrankLab PTFE Electrochemical Cell Series is a versatile, chemically inert reaction vessel engineered for routine to advanced electrochemical experiments in aggressive chemical environments.

Manufactured entirely from high-purity PTFE, these cells offer exceptional corrosion resistance, minimal background interference, and long-term durability. Two configurations are available to match different experimental requirements:

•PTFE Non-Sealed Electrochemical Cell — open or semi-open design for routine measurements

•PTFE Sealed Electrochemical Cell — fully enclosed system for controlled-atmosphere and•volatile electrolytes

With volumes ranging from 10 mL to 500 mL, this platform is widely used in electrocatalysis, materials screening, corrosion studies, and electrochemical synthesis.
