Whatman chromatography paper media are made from specially selected cotton cellulose.

They are rigorously quality controlled for characteristics important to the chromatographer and to ensure uniformity within
the grade.

Features and benefits
• 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
