Whatman 3030-917 Cellulose Chromatography Paper, Grade 3MM Chr Sheets, 46 x 57cm, 100/pk

This chromatography paper is widely used for paper chromatography, electrophoresis, and blotting techniques such as Western, Northern, and Southern transfers. Its consistent capillary action makes it ideal for separating compounds and transferring biomolecules in laboratory applications.

Grade 3MM Chr is manufactured from high-purity cotton cellulose with no additives, ensuring minimal contamination and highly reproducible results. Its uniform wicking and capillary flow make it one of the most trusted papers for reliable blotting and transfer procedures.

This product includes 46 × 57 cm sheets, 0.34 mm thickness, and a flow rate of approximately 130 mm/30 minutes. It is supplied in packs of 100 sheets and is non-sterile, making it suitable for routine laboratory use.

With a medium thickness (0.34 mm), this paper provides an optimal balance between strength and liquid flow, allowing efficient capillary movement while maintaining durability during handling and transfers.

Chromatography paper like 3MM Chr is specifically engineered for controlled solvent migration and uniform separation, which is critical for analytical techniques. Standard filter paper does not provide the same precision, consistency, or reproducibility required for chromatography and blotting workflows.
