SPE Disks and Cartridges
Waters Corp Sep-Pak Vac RC Cartridge, 20 cc, Weak Cation-Exchanger, 500 mg Sorbent, 37–55 μm
These Vac RC cartridges feature a silica-based, hydrophilic weak cation-exchanger with a large pore size (300Å). They are designed for extracting cationic analytes from aqueous and non-aqueous solutions, and their large pore size makes them suitable for isolating molecules such as cationic proteins. They can also extract steroids, pesticides, and herbicides. An integral 20 cc funnel-shaped reservoir allows convenient processing of larger sample volumes, compatible with robotic sample preparation equipment and vacuum manifolds.
