Product Details
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. The filters have a retention of 11 µm, a thickness of 0.20 mm, and a basis weight of 88.0 g/m². The paper is treated with immobilized silicone, allowing solvent to pass while retaining the aqueous phase. It is widely used in environmental studies and significantly reduces separation time compared to a separatory funnel. The filters can be utilized with a quadrant fold or cone fold in a filter funnel or simply dropped into a Buchner funnel. They may also be stacked with finer porosity filter paper or used in series for final filtration. This design reduces solvent volume waste in many applications and aids in greater recoveries. As a mature product and a laboratory staple, it is incorporated into many standard methods and SOPs.
