1PS Phase Separator for Solvent Extraction, 185mm Circle (100 pcs) SKU: 2200-185

Phase Separator Filter Paper - 2200-185

High-throughput extraction workflows benefit from a paper-based separation method that eliminates the manual draining and venting of separatory funnels. Cellulose fiber matrix provides the mechanical structure to support liquid flow while the silicone coating defines the phase boundary. On this basis, documented grade specifications provide laboratories with the technical data needed to select appropriate papers without preliminary testing.

Key Filter Paper Characteristics

• Eliminates the emulsion problems that slow separatory funnel extractions by providing a defined physical barrier between phases.
• Silicone impregnation provides permanent hydrophobic character that remains effective throughout the full extraction procedure.
• Silicone treatment penetrates the full fiber depth, providing consistent hydrophobic properties throughout the paper thickness.
• Hydrophobic surface treatment repels water-based phases while allowing organic solvents to pass through by gravity alone.
• Simplifies liquid-liquid extraction workflows by replacing glassware-intensive techniques with a single gravity-fed paper separation step.

If your teaching or research laboratory processes high volumes of routine samples, the documented flow rates above translate directly to throughput. To support this, consistent hydrophobic treatment across the paper surface ensures uniform phase separation regardless of where your organic layer contacts the filter. Elevate the quality of your analytical data today by standardizing on a filtration product built to meet the exact specifications of your applications.
