Whatman 2200-185 1PS Phase Separator Filter Paper, 185mm Diameter (Pack of 100)

Diameter: 185mm
Impregnated with a stabilized silicone that renders it hydrophobic, retaining the aqueous phase and passing the solvent phase through
Extremely rapid separation; automatically cuts off as soon as the solvent phase has passed through (note: water may break through upon prolonged standing)
Any number of separations can be processed together
Staff involvement in routine separations is at a minimum; no special training required
Whatman 1PS phase separator filter paper is impregnated with a stabilized silicone that renders it hydrophobic, retaining the aqueous phase and passing the solvent phase through. After being shaken, the mixed phases are simply poured directly into the phase separatory filter which is quadrant-folded in a funnel. The separation is extremely rapid so it is unnecessary to wait until the two phases have settled into separate layers. Droplets are automatically separated after only a few moments, giving a solvent phase completely free of the aqueous phase. Diameter: 185mm. 100/Pack. Whatman #: 2200-185.
