Sartorius' superior blotting papers

Sartorius Chromatography papers are available in a choice of different weights and thicknesses as well as in different formats. They are designed to cover the majority of blotting applications and making this simple task effortless, yet highly consistent.

  • Made of high-purity cotton linters for uniform buffer flow and resulting blots
  • No additives to avoid any interference during the transfer
  • Supplied in sheets, rolls as well as in customized sizes to save time and avoid any waste

Sartorius supplies four grades of blotting papers. Their extremely smooth surface and relatively high thickness provide them with absorption properties and superior uniformity across the entire contact area in the blotting transfer system. The grades BF 2 and BF 3 are made of cotton linters with more than 98 % alpha-cellulose content. The grades BF 1 and BF 4 are made of refined pulp and cotton linters with more than 95 % alpha-cellulose content. Higher grades have increased capillary rise; grades with higher alpha cellulose content will have greater strength and uniformity.
