Quality Control

Our Dowex Monosphere C-400 H(+)-Form is manufactured under a strict quality management system. Each batch is tested to ensure it meets stringent specifications for exchange capacity, bead integrity, and chemical stability. Certificates of Analysis (COA) detailing key performance parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperature (15-25°C). Keep away from strong oxidizing agents and strong bases. The resin is supplied moist; do not allow it to dry out, as this may cause irreversible damage to the bead structure.
