Whatman 1PS Phase Separator Paper

By Whatman/GE Healthcare
Whatman 1PS Phase Separator Paper

A high-grade filter paper impregnated with a stabilized silicone that renders it hydrophobic, retaining the aqueous phase and passing the solvent phase through.

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.After shaking, pour the mixed organic and aqueous phase directly into the quadrant-folded 1PS circle 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, providing a solvent phase completely free of the aqueous phase.
