Product Overview
Description
Spherical Chromatography Silica Gel
Porous silica remains nearly one hundred years the most often used sorbent in all chromatographic
separations. One of the reasons is its suitability of silica for surface modifications which allows to
produce new and new sorbents for range of applications. Among those the outstanding role of course
play reverse phases. Their use in preparative chromatography brought new wave of interest in silica
chemical stability.
Spherical Silica Gels allow end users to go from analytical to prep to process with the same resin.spherical silica for use at any scale of high performance liquid chromatography (HPLC): from the smallest laboratory analytical analysis to the full-scale multi-ton production line, with the same efficiency all the way. We offer spherical silica gel with pore diameters ranging from 6nm to 30nm and particle sizes from 2um to 200um.
