Whatman 3MM Chromatography Blotting Paper - 3030-6189

Whatman's cellulose chromatography and blotting papers are long-standing laboratory references for electrophoretic transfer and separation support. Pure cotton-linter cellulose carries buffer evenly through electrophoretic transfer stacks. A smooth, absorbent surface stays in even contact with the gel and backs separations and sequencing-gel lifting. For dependable sequencing-gel work, the additive-free cellulose sheet supports lifting and electrophoresis cleanly.

Key Characteristics

• Medium 0.34 mm thickness holds ample buffer for even, complete transfer
• Smooth surface stays in even contact with the gel for consistent results
• Serves as a support medium for paper chromatography and electrophoresis
• Precut sheets drop straight into transfer stacks with no trimming
• Uniform capillary wicking carries buffer evenly through the transfer stack

Steady buffer wicking and even gel contact keep every band transferring cleanly across the membrane. Uniform buffer wicking carries your transfer evenly to completion across semi-dry, tank, and capillary blotting setups. Send your transfer or chromatography setup to our technical service team and request a paper grade recommendation.

• Sample Application - Holds spotted samples evenly for chromatography and electrophoresis with no additive contamination.
• Gel Electrophoresis - Supports sequencing-gel lifting and electrophoretic work with a smooth, uniform cellulose surface.
• Western Blot Transfer - Wicks transfer buffer evenly through the gel-to-membrane stack for complete, reproducible protein transfer.
• Sequencing Gel Lifting - Backs and lifts polyacrylamide sequencing gels on a smooth, additive-free cellulose surface for clean handling.
• Paper Chromatography - Serves as a pure-cellulose support medium for separating sample components by capillary migration.
• Capillary Transfer - Wicks transfer buffer upward through the gel and membrane to move proteins and nucleic acids by capillary flow.
