CYCLOBOND is the name given to Astec′s technology of bonding beta- and gamma- cyclodextrins to a high purity 5μ silica gel. This patented process was developed to produce a stable ether linkage, with the cyclodextrin arranged in such a way as to retain its most valuable property of forming inclusion complexes. Chemical separations are effected by selective inclusion of a wide variety of organic molecules from solution into the cyclodextrin cavity.
