Grade CFP1234 Phase Separating Cellulose Filter Paper, 11µm, 125mm, Silicone-Treated, 100/Pk SKU: LE-CFP1234-1250

Featuring silicone-treated cellulose technology delivering hydrophobic barrier performance that creates a hydrophobic barrier that can replace a separatory funnel to separate organic solvents from aqueous phase. The 11µm retention configuration provides fast flow rate with similar retention to qualitative Grade CFP1 filter paper while maintaining exceptional chemical selectivity for organic/aqueous phase separations. Immobilized silicone treatment allows solvent to pass and retains aqueous phase, delivering reliable performance for environmental analytical protocols requiring rapid liquid-liquid extractions.

Key Silicone-Treated Membrane Characteristics

• Hydrophobic silicone treatment creates selective barrier allowing organic solvents to pass while retaining aqueous phase
• 11µm particle retention delivers fast flow rates optimized for high-volume sample processing applications
• 0.20mm thickness provides mechanical stability during folding and handling without compromising filtration performance
• 88.0g/m² basis weight ensures consistent porosity and flow characteristics across the entire filter surface
• Cellulose matrix construction maintains chemical compatibility with most organic solvents and aqueous solutions

Key Construction Characteristics

• 125mm diameter accommodates standard filter funnels and Buchner funnel configurations for versatile laboratory use
• Quadrant fold or cone fold capability enables direct use in filter funnels without pre-folding equipment
• Stackable design allows series filtration with finer porosity papers for enhanced final filtration results
• Non-sterile construction optimized for analytical applications where sterility is not required
• Mature product design integrated into established environmental studies and reduces separation time significantly compared to separatory funnel

LE-CFP1234-1250 filters achieve exceptional separation efficiency while reducing separation time significantly compared to separatory funnel, accelerating your analytical workflows for environmental monitoring and organic extraction procedures. Outstanding chemical resistance and selective permeability maximize your laboratory productivity by reducing solvent volume waste and enabling greater recoveries in liquid-liquid extraction protocols. This mature filtration technology transforms complex separation procedures into streamlined analytical steps, providing reliable performance for environmental laboratories requiring validated phase separation capabilities with established method compatibility.
