General description

0.34 mm Whatman medium thickness 3MM Chr paper. Whatman 3MM Chr paper is the world’s most widely used blotting paper. This acceptance and usage reflect the high quality, purity, and consistency that are relied upon by researchers doing Southern, Northern, and Western transfers. 3MM Chr paper is now available in the most widely used sizes. A medium thickness paper (0.34 mm) is used extensively in electrophoresis for lifting of sequencing gels. 3MM Chr is also used both in electrophoresis and for general chemistry. A medium thickness paper (0.34 mm) used extensively for general chromatography and electrophoresis.

Features and Benefits

  • Pure cellulose produced entirely from the highest quality cotton linters with no additives of any kind. Ensures that no contamination will occur during the transfer steps.
  • Manufactured and tested specifically for chromatographic and blotting techniques. This ensures the wicking capability and uniformity of capillary action that are important in obtaining clean and even transfers during blotting.
  • Whatman 3MM Chr is considered the industry standard for blotting procedures.
  • Convenient sizes available in sheets precisely cut to the most popular gel and transfer membrane sizes. Allows "out-of-the-box" usage and eliminates sheet-to-sheet variations.
