Hamilton HPLC Guard Column Starter Set, PRP-3, 10 μm, 2.1 x 20 mm, 1 Holder, 2 Cartridges

PRP-3 particles come with a larger (300 Å) pore size for protein separation. No silanol groups on the resin means no irreversible protein adsorption, giving > 90% analyte recovery. This stable material also allows the use of concentrated acids, chaotropes, and even detergents to minimize problems with protein solubility.
