Normal Phase Resprep™ SPE Cartridges
By Restek
Hydrophilic (polar) adsorbents used to extract hydrophilic analytes from nonpolar matrices, such as organic solvents (e.g., polar contaminants from sample extracts). All cartridges are manufactured using high density polypropylene and have polyethylene frits unless otherwise noted. Cartridges may be processed by any one or all of these techniques: positive pressure, sidearm flask, centrifuge, or vacuum manifold.
