Electrophoresis Blotter Cards, Double Thick, 75x100mm, High Flow Cotton Cellulose, 50/Pk SKU: LE-CFP1700-005

Featuring double-thick cotton cellulose construction delivering exceptional buffer flow and absorption capacity for gel electrophoresis applications. High purity cotton fibers with controlled absorption characteristics provide consistent wicking performance across protein and nucleic acid blotting protocols. The 75mm x 100mm format accommodates standard gel transfer configurations while maintaining uniform contact throughout the blotting sandwich assembly.

Key Cotton Cellulose Membrane Characteristics

• 100% FDA-compliant alpha cotton cellulose construction eliminates additives that could increase backgrounds or interfere with detection systems
• Controlled absorption with uniform distribution across the sheet delivers consistent buffer flow without hard spots or density variations
• Smooth and uniform texture ensures continuous contact of buffer from chamber through gel and transfer membrane to opposite pole
• Excellent wet-strength and handling characteristics prevent tearing during buffer saturation and gel manipulation
• Lot-to-lot consistency with no airborne fibers maintains reproducible results across experimental protocols

Key Construction Characteristics

• Double-thick configuration maximizes buffer capacity while maintaining rapid absorption speed for extended transfer times
• Thick papers are ideal for chromatography techniques where solutes are heavily loaded
• Extremely high flow characteristics recommended for both electrophoresis of large molecules and blotter completion in gel transfer applications
• 75mm x 100mm dimensions provide optimal coverage for standard mini-gel formats and Western blot configurations
• High purity construction with no sizing or fillers eliminates potential interference with downstream detection methods

These blotter cards achieve superior buffer distribution optimized for Southern, Northern, and Western blot applications, accelerating your protein and nucleic acid transfer protocols. Essential for nucleic acid research including electroblotting and electrophoresis techniques, the double-thick construction maximizes your gel transfer efficiency while maintaining the structural integrity required for consistent laboratory workflows and reproducible analytical results.
