Gel Filtration Chromatography Resin

Gel filtration chromatography achieves the purpose of separation according to the size of solute molecules. Gel filtration chromatography is also known as volume exclusion chromatography, molecular sieve chromatography. Gel filtration chromatography media are inert spherical granular materials with a porous network structure.

GALAK provides two types of gel filtration media: crosslinked agarose microspheres and crosslinked glucan microspheres.

GLKgel GFC Agarose Media

GALAK has two types of agarose gel filtration media: 4% and 6% agarose gel. Crosslinked agarose gel (CL) is a low-strength crosslinking agarose gel with better physical and chemical stability. High-velocity agarose gel (FF) is high strength crosslinking agarose gel with good physical and chemical stability, can be sterilized by heat and humidity, and withstand various working conditions in protein production.
