High grade filter paper impregnated with a stabilised silicone that renders it hydrophobic, retaining the aqueous phase and passing the solvent phase through.

• Any number of separations can be processed together
• The cut-off is automatic and complete, can replace separating funnels

Solvent extraction can be time-consuming and messy when numerous separations are required

Mixed phases are poured directly into the 1PS phase-separating paper. 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.
