Grade CFP1234 Cellulose Phase Separating Filter Paper, 11µm, 90mm, Fast Flow, 100/pk SKU: LE-CFP1234-0900

Featuring immobilized silicone treatment delivering selective phase separation technology that creates a hydrophobic barrier that can replace a separatory funnel to separate organic solvents from aqueous phase. This grade demonstrates a fast flow rate with similar retention to qualitative Grade CFP1 filter paper, providing 11µm particle retention with 0.20mm thickness and 88.0g/m² basis weight. Ultra-pure cellulose construction with precision phase separation capabilities accelerates environmental analysis protocols while eliminating separatory funnel requirements and reducing processing time significantly.

Key Cellulose Membrane Characteristics

• Immobilized silicone treatment allows organic solvents to pass through while retaining aqueous phase for precise separation
• 11µm nominal particle retention delivers optimal filtration efficiency for environmental and analytical applications
• Fast flow properties maximize throughput while maintaining consistent separation performance across sample types
• 88.0g/m² basis weight provides structural integrity during extended filtration cycles and sample processing
• Hydrophilic cellulose matrix ensures reliable wetting and consistent performance with aqueous solutions

Key Construction Characteristics

• 0.20mm thickness measured under controlled conditions using TAPPI T411¹ standard methodology ensures consistent dimensional stability
• 90mm diameter accommodates standard laboratory filtration equipment and Buchner funnel configurations
• Quadrant fold or cone fold compatibility provides versatility for use in filter funnels or direct placement applications
• Stackable design enables series filtration with finer porosity papers for multi-stage separation protocols
• Mature product formulation written into established standard methods and SOPs for regulatory compliance

CFP1234 filters are widely used in environmental studies and reduce separation time significantly compared to separatory funnel methodologies, reducing solvent volume waste in many applications and aiding in greater recoveries. May be stacked with finer porosity filter paper or used in series for final filtration, providing exceptional flexibility for complex analytical protocols demanding both rapid processing and validated separation performance in environmental monitoring and organic extraction applications.
