Cytiva 1PS Phase Separator Filter Paper

Description

• Whatman 1PS Phase Separator is a high-grade filter paper impregnated with a stabilised silicone that renders it hydrophobic Whatman 1PS 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
• In many applications, 1PS can replace the use of separatory funnels
• In a typical application, samples are shaken with solvent in stoppered conical flasks or test tubes and the mixed phase simply poured directly into an 1PS circle 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, leaving a solvent phase completely free of the aqueous phase
• 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 simultaneously
• 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 such that skilled supervision is not required
• Water may break through upon prolonged standing
• Ease of use: No special training required
• Any number of separations can be processed together
• Personnel intervention in routine separations kept at a minimum.
