SPE Disks and Cartridges
Waters Corp Sep-Pak C18 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 100/pk
Sep-Pak C18 Vac cartridges contain a hydrophobic, reverse-phase, silica-based bonded phase that is used to adsorb analytes of even weak hydrophobicity from aqueous solutions. The Sep-Pak C18 sorbent is made using the most reproducible bonding technology available, utilizing monofunctional silane chemistry. This sorbent offers a unique selectivity and excellent recovery of anlytes, and is recommended as a general purpose SPE phase for both polar and non-polar analytes. Typical applications include extraction of drugs and their metabolites in serum, plasma or urine, desalting of peptides, isolation of trace organics in environmental water samples and organic acids in beverages. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Oasis Vac Cartridge, MCX, 6 cc, 150 mg, 60 μm
These 6 cc cartridges feature a novel, mixed-mode polymeric sorbent, optimized for high selectivity and sensitivity in extracting basic compounds with cation-exchange groups. Its water wettable nature ensures excellent recoveries even when run dry. With a 60 μm particle size, it is ideal for viscous samples and is compatible with vacuum manifolds and automated SPE instruments.
- Optimized for high selectivity and sensitivity in basic compound extraction.

Waters Corp Sep-Pak Alumina A 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 50 - 300 µm, 100/pk
Sep-Pak Alumina A Vac cartridges contain a highly active grade of alumina with an acidic surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This acidic alumina is also low-capacity ion exchanger in aqueous media. Unlike polymer-based ion exhangers, this sorbent is unaffected by high-energy radioactivity and can be used for radioactive compound isolation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
