Whatman Phase separator paper 1PS 12.5cm Pack of 100

The 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.

Features and Benefits

• Ease of use - no special training required
• Any number of separations can be processed together
• Staff involvement in routine separations is at a minimum

Automatic Cut-Off, Separatory Funnel Replacement
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.
