325 Mesh Wood Based Powder Activated Carbon for Pharmaceutical Intermediate Purification
Product Introduction
Wood-based powdered activated carbon is specifically engineered for the refining and purification of pharmaceutical intermediates in chemical synthesis and fermentation processes.
It effectively removes colored substances, trace catalysts, residual organic impurities, and by-products from reaction or fermentation solutions, ensuring high purity, stability, and compliance with stringent pharmaceutical standards.
Manufactured from selected hardwood raw materials and activated under precisely controlled conditions, this 325 mesh fine-grade carbon provides a large surface area, high micropore volume, and uniform particle size distribution — delivering exceptional adsorption efficiency and fast filtration performance in pharmaceutical intermediate refining.
