WHATMAN(TM) CELLULOSE CHROMATOGRAPHY PA

General description

Grade 1 ChrThe world standard chromatography paper. A smooth surface, 0.18 mm thick with a linear flow rate (water) of 130 mm/30 min. Good resolution for general analytical separations.Grade 2 ChrThickness 0.18 mm. Flow rate 115 mm/30 min. Slower than 1 Chr for higher resolution applications. Smooth surface. Particularly recommended for optical or radiometric scanning.Grade 3MM ChrThough widely used as a blotting paper, 3MM Chr is also used both in electrophoresis and for general chemistry. A medium thickness paper (0.34 mm) used extensively for general chromatography and electrophoresis. Flow rate is 130 mm/30 min.Grade 4 ChrThickness 0.21 mm. Flow rate 180 mm/30 min. Fastest of the thin papers. Recommended for routine and/or repetitive chromatography when loadings are relatively low. Smooth surface. Very suitable where speed is important and very high resolution is not required.Grade DE 81 DEAE cellulose paper. Weakly basic anion exchanger. Thin paper with medium flow rates.Grade 2668 ChrThickness 0.9 mm. Flow rate 155 mm/10 min. For separation of relatively large molecules by electrophoresis.
