Aluminium sheets (about 0.1mm thick) are used as support for TLC ready to use layers.
For ALUGRAMÂ® sheets a support of plain aluminium foil is coated using the same binder system as for TLC glass plates. For eluents containing high concentrations of water we recommend POLYGRAMÂ® precoated sheets.
With ALUGRAMÂ® precoated sheets problems might arise when using eluents which contain high concentrations of mineral acids or concentrated ammonia (which attack the aluminium). In such cases we recommend using our glass plates or polyester sheets.
