Descriptions

SEPLITE® Monojet™SA8500U Ion Exchange Resin is a high-purity, high-capacity resin with uniform particle size designed specifically for the primary, second loop or polishing stage in ultrapure water preparation. This resin can be available in both OH⁻ form and Cl⁻ form, with the ionic conversion rate of OH⁻ form up to 95%. It is normally paired with SEPLITE® Monojet™SC7700U in H⁺ form in mixed bed systems.

Precautions

• Resins should be stored in sealed containers or bags where the temperature is above 0℃ in dry conditions without exposure to direct sunlight.
• Do not mix ion exchange resin with strong oxidizing agents; otherwise, it will cause violent reactions.
• In case of eyes contact with resins, rinse eyes immediately with plenty of water and consult a specialist.
• Material and samples must be disposed of according to local regulations.
• Dry polymers will expand when become wetted and may cause an exothermic reaction.
• Spilled materials may be slippery.
