Whatman CHR Paper
Excellent for the following applications:
- Semi-dry blotting
- Tank blotting
- Capillary blotting
- Gel drying
- Gel wicking
The world’s most widely used blotting paper is a medium thickness paper (0.34 mm) with a flow rate (water) of 130 mm/30 min. Specifically produced and tested for chromatographic techniques to ensure wicking capability and uniform capillary flow. These characteristics are important for reproducible high-quality blotting results. Pure cellulose produced entirely from the highest quality cotton linters with no additives of any kind to ensure 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.
Thick (0.92 mm) and highly absorbent paper with a very high flow rate (water) of 190 mm/30 min. Suitable for preparative paper chromatography and electrophoresis applications such as gel wicking and blotting.
An extra-thick (1.5 mm), highly absorbent paper recommended for applications where fewer layers of blotting paper but high capacity are required. Fewer layers of blotting paper reduce the risk of trapping air bubbles. Recommended for semi-dry blotting of proteins.
