Grade CFP1234 Phase Separating Cellulose Filter Paper, 11µm, 185mm, Silicone-Treated, 100/Pk SKU: LE-CFP1234-1850

Featuring immobilized silicone technology that creates a hydrophobic barrier for efficient organic-aqueous phase separation without traditional separatory funnels. This paper is treated with immobilized silicone which allows solvent to pass and retains aqueous phase, delivering exceptional separation efficiency with fast flow rate with similar retention to Qualitative Grade CFP1 filter paper. Advanced 11µm retention capability combined with 0.20mm thickness and 88.0g/m² basis weight optimizes filtration performance while maintaining consistent separation characteristics for environmental analysis applications.

• Immobilized silicone coating creates selective permeability allowing organic solvents to pass while retaining aqueous phases
• Hydrophobic barrier technology eliminates need for separatory funnels, accelerating sample processing workflows
• Reduces separation time significantly compared to separatory funnel methods in environmental studies
• Superior chemical resistance maintains filtration integrity across diverse organic solvent applications
• Fast flow rate characteristics optimize throughput while preserving 11µm particle retention precision

• 185mm diameter configuration accommodates standard filtration equipment and high-volume environmental sampling protocols
• Uniform 0.20mm thickness with 88.0g/m² basis weight delivers consistent mechanical strength and flow characteristics
• Quadrant fold or cone fold for use in a filter funnel or simply drop the filter disk into a Buchner funnel
• May be stacked with finer porosity filter paper or used in series for final filtration applications
• Cellulose matrix construction provides biodegradable substrate while maintaining filtration performance standards

Reduces solvent volume waste in many applications and aids in greater recoveries, maximizing your analytical efficiency while minimizing environmental impact. Versatile installation options support both gravity-fed and vacuum-assisted filtration systems, adapting seamlessly to existing laboratory configurations. This is a mature product and lab staple written into many standard methods and SOP's, providing validated performance assurance for critical environmental monitoring, organic extraction, and analytical chemistry applications requiring reliable phase separation capabilities.
