Merck TLC Silica Plates Aluminium (25 Sheets 20 x 20 cm) Filter Paper  (20 cm)

Silica gel is the most universal adsorbent used in TLC because it covers almost every type of separation by suitable choice of the mobile phase. EMD Millipore classical silica TLC plates are based on proven EMD Millipore silica gel 60 with a pore diameter of 60 Å, a pore volume of 0.8 mL/g and a specific surface of 520 m2/g (BET). The unique polymeric binder results in a very adherent and hard surface that will not crack or blister and even allows writing with a pencil on the surface without risk of damaging the layer. The smooth and dense plate surface guarantees sharp bands for maximum separation efficiency with lowest background noise, e.g. when performing scanning densitometry. Classical silica TLC plates have either a layer thickness of 250 µm (glass plates) or 200 µm (aluminum, plastic plates) and a mean particle size of 10 - 12 µm. They are available glass, aluminum or plastic backed in a broad range of different sizes to suit many application needs. The flexible backed aluminum or plastic plates can easily be cut with scissors to match individual separation requirements.
