Product Overview

Description



Spherical Chromatography Silica Gel


 Sphere Silica.jpg


 


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.
