Whatman chromatography papers are the most extensively used papers for chromatography worldwide. This acceptance and usage reflect along with, The purity consistency of, Premium standard whatman papers. These qualities are relied upon by chromatographers and are essential to successful, Reproducible chromatography. Whatman chromatography paper media produced using specially selected cotton cellulose. They are rigorously quality controlled for characteristics important to the chromatographer and to ensure uniformity within the grade. The chromatography paper product line includes standard cellulose and ion exchange grades. Advantages and characteristicspure cellulose produced entirely from top-tier quality cotton linters with no additives of any kindmanufactured and tested specifically for chromatographic techniques this ensures the wicking capability and uniformity of capillary action that are important in chemical separations.
