Ahlstrom Grade 222: 0.83 mm Thickness, 220 mm /30 min. Absorption Speed. This medium thick paper offers extremely high flow and is recommended for both electrophoresis of large molecules and as a blotter to complete the blotting sandwich in gel transfer applications. Ahlstrom 222 has a smooth and uniform texture which assures continuous contact of buffer from the chamber through the gel and transfer membrane to the opposite pole or weight. Thick papers are 100% cotton grades that are used in chromatography techniques where solutes are heavily loaded. Thick papers are ideal grades for electrophoresis techniques.
