Super 70 – a series of Macroporous Adsorbent Resin designed for the polishing purification and separation for pharmaceuticals and natural products. These resins are non-monodispersed resin with narrow particle size distribution, with the advantages of high resolution and loading capacity and long shelf-life. It made from highly cross-linked polymers of styrene and divinylbenzen, has an excellent pH stability over a wide range of pH 1-14; especially shows outstanding stability in extremely acidic or alkaline solutions (such as 1mol/L HCl\NaOH) and organic solvents ( such as methanol, ethanol, acetone, n-propanol, isopropanol, DMSO, THF, acetonitrile, 6 M guanidine hydrochloride, etc.
