Quality Control

Our PEDOT:PSS is manufactured under stringent process controls to ensure batch-to-batch consistency in conductivity, viscosity, and solid content. Quality is verified through a suite of analytical techniques including conductivity measurement, particle size analysis, and spectroscopic identification. A Certificate of Analysis (COA) detailing key parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store at room temperature (15-25°C). The aqueous dispersion is stable under these conditions. Avoid freezing and prolonged exposure to elevated temperatures. For long-term storage beyond one year, performance should be verified prior to use.
