The "AP Series" is a silica gel for separation and purification that offers high cost performance and stable quality. It is manufactured using a unique classification and purification method, featuring a silica gel with an average pore diameter of 60Å, which is highly versatile as a chromatographic silica gel. In the water treatment process during manufacturing, natural groundwater with lower chloride ion content than general industrial water is used, resulting in very few impurities and enabling high-quality, high-precision separations. 【Features】 ■ Crushed silica gel ■ Manufactured using a unique classification and purification method ■ High and stable cost performance and quality ■ Very few impurities, allowing for high-quality and high-precision separations ■ Usable in a wide range of fields from column chromatography to large-scale fractionation *For more details, please refer to the PDF document or feel free to contact us.
