Vitamin B12 is a crucial water-soluble vitamin for the human body, playing an important role in the production of red blood cells, the normal functioning of the nervous system, and the synthesis of DNA. When it comes to the extraction of Vitamin B12, ion exchange resin becomes a key tool. By using ion exchange resin, Vitamin B12 can be effectively separated and purified from various sources. Jiangsu Kingshan New Material Co., Ltd. (www.bojieresin.com), with its own brand Bestion, is a large company in this industry. The PC165 they developed is a large-pore weak acid cation exchange resin, designed specifically for Vitamin B12 extraction. This product not only has efficient extraction capabilities but also boasts a long service life, widely welcomed and praised by customers both domestically and internationally.
