Description

For use in normal or reverse phase HPTLC. Macherey-Nagel™ Alugram™ RP-18 W/UV₂₅₄ Modified Silica Phase are aluminum sheets coated with wettable layers of modified nano silica that can be developed with purely organic and organic/aqueous solvents and purely aqueous eluents.

Alugram™ aluminum sheets are easy to handle, lightweight and flexible. The sheets have high chemical resistance and are suitable for most solvents. They are unbreakable but easy to cut with scissors, with no flaking of the silica.
