RR99819 - 20um PE Filtration 6ml, pk/100

20μm PE Filtration Columns

Typical applications include:

• Isolation of precipitates or crystallites from the reaction mixture
• Filtration of resins prior to cleavage
• Filtration of solid supported reagents post synthesis
• Removal of solid impurities prior to SPE
• In the first two cases the Filtration Columns are used in the ‘Lower Level’ as subsequent SPE is not required. Pressure can be applied to the Columns using the Acrylic Gas Cover to increase the flow rate. If individual Columns are slow or become blocked pressure can be applied to individual columns using the appropriate tapered adapter. The crude product or resin is washed prior to isolation or cleavage etc as required.

Solid impurities, for example salts may be removed using the Filtration Columns in the ‘Upper Level’ prior to SPE in the ‘Lower Level’.
