Waters Corp Sep-Pak Silica Vac RC Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Polar sorbent, used primarily to adsorb analytes from non polar solvents like hydrocarbons, chloro- or flouro-substituted hydrocarbons or less polar esters and ethers.
Waters Corp Sep-Pak C18 Vac RC Cartridge, 100 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Silica-based bonded phase with strong hydrophobicity; used to adsorb analytes of even weak hydrophobicity from aqueous solutions; typical applications include drugs and their metabolites in serum, plasma or urine, desalting of peptides, trace organics in environmental water samples, organic acids in beverages; similar in behavior to reversed-phase HPLC columns.
Waters Corp Sep-Pak Accell Plus QMA Vac RC Cartridge, 100 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus QMA Vac RC cartridges contain a silica-based, hydrophilic, strong anion-exchanger with large pore size (300Å). The cartridges are designed for extraction of anionic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of larger molecules such as anionic proteins such as immunoglobulins and enzymes. Other applications include isolation of phenolic compounds and removal of acidic pigments in wine, fruit juices, and food extracts. These cartridges feature an integral 20 cc funnel-shaped reservoir for convenient processing of larger volumes of samples. They can be used with robotic sample preparation equipment or with vacuum manifolds.
Waters Corp Sep-Pak C8 3 cc Vac RC Cartridge, 500 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Silica-based bonded phase with moderate hydrophobicity; use for methods requiring less retention than C18; typical applications include drugs and their metabolites in serum, plasma or urine, peptides in serum, plasma.
Waters Corp Sep-Pak C18 Classic Cartridge, 360 mg Sorbent per Cartridge, 55 - 105 µm, 2000/pk
Silica-based bonded phase with strong hydrophobicity; used to adsorb analytes of even weak hydrophobicity from aqueous solutions; typical applications include drugs and their metabolites in serum, plasma or urine, desalting of peptides, trace organics in environmental water samples, organic acids in beverages; similar in behavior to reversed-phase HPLC columns.
Waters Corp Sep-Pak Alumina A 35 cc Vac Cartridge, 10 g Sorbent per Cartridge, 50 - 300 µm, 10/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.
Waters Corp Sep-Pak Cyanopropyl (CN) 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 55 - 105 µm, 30/pk
Silica-based polar bonded phase; can be used as less polar alternative to silica in normal-phase applications or as less hydrophobic alternative to C18 or C8 in reversed-phase applications; typical applications include drug metabolites and pesticides.
Waters Corp Sep-Pak Diol 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 37 - 55 µm, 30/pk
Silica-based polar bonded phase with neutral character; can be used as an alternative to silica in normal-phase applications, where the acidic character of silica is undesirable or as very weakly interacting phase in aqueous applications; applications include antibiotics from cosmetics; isolation of proteins or peptides by hydrophobic interaction chromatography.
Waters Corp Sep-Pak Accell Plus QMA 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 37 - 55 µm, 30/pk
Sep-Pak Accell Plus QMA Vac cartridges contain a silica-based, hydrophilic, strong anion-exchanger with large pore size (300Å).

Waters Corp Certified Sep-Pak Florisil 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 50 - 200 µm, 30/pk
6 cc Vac Cartridge of Certified Sep-Pak Florisil, each containing 1 g of sorbent per cartridge.
Waters Corp Certified Sep-Pak Silica 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 30/pk
Certified Sep-Pak Silica Vac cartridges contain a polar sorbent that is used primarily to adsorb analytes from non-polar solvents like hydrocarbons, chloro- or fluoro-substituted hydrocarbons, or less polar esters and ethers. Certified Sep-Pak Silica Vac cartridges can also be used in an aqueous medium as a cation exchanger of intermediate strength. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments. Certified Sep-Pak Silica cartridges are quality controlled to ensure reproducible separations. The cartridges provide superior performance for ultra-low-level analyte detection by reducing the potential for background interferences found in many SPE devices. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
