1PS Phase Separator, circle, 125 mm 1PS phase separators, circles. Ease of use: No special training required. Any number of separations can be processed together. Staff involvement in routine separations is at a minimum. Whatman 1PS Phase Separator is a high-grade filter paper 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 1PS circle, 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. In many applications, 1PS can replace the use of separatory funnels. The solvent phase flows through the paper quickly and cleanly. It then stops automatically, leaving the aqueous phase completely in the paper. This feature is particularly important when carrying out a large number of routine solvent extractions at the same time. Samples can be shaken with solvent in stoppered conical flasks or test tubes and transferred directly to funnels containing 1PS. Automatic cut-off, separatory funnel replacement A chief benefit of the 1PS method is that cut-off is automatic and complete just as soon as the solvent phase has passed through. The result is no skilled operators are required. Water may break through upon prolonged standing. Unsupervised separation
