These cellulose filters create 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
• Paper is treated with immobilized silicone which allows solvent to pass and retain aqueous phase
• Reduces solvent volume waste in many applications and aids in greater recoveries

Widely used in environmental studies to reduce separation time significantly compared to a separatory funnel. 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. This is a mature product and lab staple written into many standard methods and SOP's.
