GE Healthcare Life Sciences offers an extensive line of pure cellulose filter paper products, including Whatman 3MM Chr which is considered a standard for blotting procedures. All types of blotting paper are available in sheets precisely cut to the most popular gel and transfer membrane sizes, allowing ‘out-of-the-box’ usage and eliminating sheet-to-sheet variations.

Our pure cellulose blotting papers are manufactured from the highest quality cotton linters with no additives to ensure that no contamination will occur during the transfer steps. The filter papers are manufactured and tested specifically for chromatographic and blotting techniques. This supports the wicking capability and uniformity of capillary action that is important for obtaining clean and even transfers during blotting
