Impregnated with stabilized silicone to create a hydrophobic filter Multiple separations can be processed in parallel No special training required Can replace a separatory funnel in certain applications Whatman 1PS Phase Separator from Cytiva's business is a hydrophobic filter for routine solvent extraction. Within seconds it retains aqueous phases, while solvent phases flow through. Hydrophobic solvent extraction paper Solvent extraction can be timeconsuming and messy when numerous separations are required. Cytiva's Whatman 1PS Phase Separator is impregnated with stabilized silicone, creating a hydrophobic filter paper that can replace separatory funnel use in certain applications. Rapid solvent extraction Mixed phases are poured directly into the Whatman 1PS Phase Separator filter. The solvent phase flows through the paper quickly and cleanly, automatically stopping after the process is complete; all of the aqueous phase is retained. Droplets are automatically separated within seconds.
