Phase separator filter paper –
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 our Qualitative Grade CFP1 filter paper.
Retention: Thickness: Basis weight:
11μm 0.20mm 88.0g/m2
This paper is treated with immobilized silicone which allows solvent to pass and retains aqueous phase.
Widely used in environmental studies and reduces separation time significantly compared to separatory funnel.
