Whatman 3004-917 Grade 4 Chr Cellulose Chromatography Paper, sheet, 46 × 57 cm, 100 per pack

Thickness .21 mm. Flow rate 18 mm/3 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.

Features:

• Pure cellulose produced entirely from the highest quality cotton linters with no additives of any kind.
• Manufactured and tested specifically for chromatographic techniques. This ensures the wicking capability and uniformity of capillary action that are important in chemical separations.
• Also widely used in protein and nucleic acid blotting.
