Whatman 1 PS Phase Separator
The Whatman 1 PS Phase Separator is a high grade filter paper
impregnated with a stabilised silicone that renders it hydrophobic,
retaining the aqueous phase and passing the solvent phase through.
Automatic Cut-Off, Separatory Funnel Replacement
After being shaken, the mixed phases are simply poured directly into the
1 PS circle which is quadrant-folded in the 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, 1 PS 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 1 PS.
Unsupervised Separation
A chief benefit of the 1 PS 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.
Features and Benefits
- Ease of use. No special training required
- Any number of separations can proceed together
- Staff involvement in routine separations is at a minimum
Safety
Water may break through upon prolonged standing.
