3MM Chr
The world’s most widely used blotting paper is a medium thickness paper (0.34 mm) with a fl ow rate (water) of 130 mm/30 min.  
Specifi cally produced and tested for chromatographic techniques to ensure the wicking capability and uniformity of capillary action that is important for reproducible high-quality of blotting results. Pure cellulose produced entirely from the highest quality cotton linters with no additives of any kind to ensure that no contamination will occur during the transfer steps. This paper is available in convenient sizes as sheets precisely cut or as rolls for cutting individual length.

17 Chr
Thick (0.92 mm) and highly absorbent paper with a very high fl ow rate (water) of 190 mm/30 min. Suitable for the heaviest loadings and ideal for preparative paper chromatography and electrophoresis applications like gel wicking and blotting.

An extra-thick (1.5 mm), highly absorbent paper recommended for applications where fewer layers of blotting paper must still ensure a high capacity. Fewer layers of blotting paper reduce the risk of trapping air bubbles. Recommended for semi-dry blotting of proteins.
