ADDITIONAL INFORMATION
Oasis and Sep-Pak cartridges are not designed to process samples by gravity flow. They are intended to be used with either vacuum or positive pressure.
Gravity flow may be possible if samples and solvents used in the method are not too viscous.
Waters offers PoraPak Rxn RP (reverse phase) and PoraPak Rxn CX (mixed mode strong cation exchange) cartridges, which are specifically designed for gravity-flow cleanup of synthetic reaction mixtures.
