Special resin for amino acid extracting - SA-2

SA-2 Special resin for amino acid extracting
1. Description
It is a kind of new product which specially used for extraction of amino acid, with modern technics “twice polymerization with once pore-forming”. It has suitable skeleton construction, uniform pore size, and particular micropore constitution, so it can work with large exchange capacity, strong anti-penetration performance and good physical strength. When adsorbing the amino acid, it proves that it has large adsorptive capacity ( general size: ＞140kg/m3,improved type can work better), speedy adsorption and elution, Strong contamination resistance and long useful life. Our this product has been appraised by specialist of USTC (University of Science and Technology of China), the quality has reached international advanced level in the like products
