Ahlstrom 6171-0707 Chromatography Blotting Paper (Cellulose), Grade 617, 7" x 7", 500/pk

Grade 617 blotting paper is designed for rapid liquid absorption and transfer in laboratory workflows. It is commonly used in chromatography support, electrophoresis blotting, gel drying, and general lab blotting procedures where fast wicking and reliable performance are required.

Grade 617 is known for its fast filtration speed, thicker structure, and higher loading capacity compared to many standard grades. This makes it particularly effective for handling larger volumes of liquid and coarse or gelatinous materials without tearing or breakthrough.

Yes. Ahlstrom chromatography and blotting papers are manufactured from high-purity cotton linters and are free from additives, helping minimize contamination during sensitive analytical procedures such as Western, Northern, or Southern blotting.

Absolutely. The 7 × 7 inch sheets can be easily trimmed with clean laboratory scissors or cutters to match specific gel sizes, transfer stacks, or chromatography setups, making them flexible for a wide range of protocols.

Store the paper in a clean, dry environment at room temperature and keep it sealed in its original packaging until use. Avoid high humidity and direct contamination to preserve its absorbency, purity, and structural integrity.
