Silica Gel Hard Layer TLC Plates
Silica Hard Layer (HL) is a family of precoated glass plates with unmodified silica. It is available in two types as Silica Hard Layer for TLC and Silica Hard Layer for HPTLC. Silica Hard Layer plates differ from the well-known plates Silica Soft Layer (SL) TLC and Silica SL HPTLC by a special binder system, resulting in the formation of hard, water-resistant and wettable layers with outstanding separation properties and consistent reproducibility from lot to lot.
