Waters Corp Sep-Pak Accell Plus CM Plus Short Cartridge, 360 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus CM Plus Short cartridges contain a silica-based, hydrophilic weak cation-exchanger with large pore size (300Å). The cartridges are designed for extraction of cationic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of molecules such as cationic proteins. Other applications include extraction of steriods, pesticides, and herbicides. These cartridges are provided in the short-body configurations for easily attachment to pumps and syringes. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems.

Waters Corp Sep-Pak C18 1 cc Vac Cartridge, 50 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 HLB 3 cc Vac Cartridge, 60 mg Sorbent per Cartridge, 30 µm, 100/pk
The 3 cc Oasis HLB cartridges contain the Oasis HLB sorbent, which is a universal polymeric reversed-phase sorbent that was developed for the extraction of a wide range of acidic, basic, and neutral compounds from various matrices using a simple, generic protocol. Since the Oasis HLB sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
