Geduran® SI 60 Silica Gel is useful in column chromatography.

Supplier: MILES SCIENTIFIC CORP

These plates are 100% water resistant and are compatible with aqueous developing solvents for efficient separations.

Supplier: MERCK, S.A. DE C.V. SV

Classical silica TLC plates are based on a combination of proven silica gel 60 and the addition of a unique polymeric binder resulting in a very adherent and hard surface that will not crack or blister and even allow writing with a pensil on the surface without risk to damage the layer.

Supplier: MERCK, S.A. DE C.V. SV

RP-modified plates serve two purposes: Act as a pilot method for HPLC and allow to choose various solvent system for special separations
