COSMOSIL Buckyprep-M

Specialty for Fullerenes / For Metallofullerenes

COSMOSIL Buckyprep-M is a phenothiazinyl group bonded silica based column specifically designed for metallo-fullerene separation. Metallo-fullerenes are retained more strongly than other fullerenes on this column. COSMOSIL Buckyprep-M is also effective for the separation of higher fullerenes and fullerene derivatives.
