SPE Disks and Cartridges
Waters Corp Sep-Pak Alumina A Plus Long Cartridge, 1710 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina A Plus Long 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 versatile cartridges can attach easily to pumps and syringes for reliable, positive-pressure flow to speed up the sample processing time. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems.
Waters Corp Sep-Pak Accell Plus CM 35 cc Vac Cartridge, 10 g Sorbent per Cartridge, 37 - 55 µm, 10/pk
Sep-Pak Accell Plus CM Vac 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 syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak C8 Plus Light Cartridge, 145 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 Oasis WCX Online Prospekt-2/Symbiosis Cartridge, 80Å, 30 µm, 10 mm, 96/pk
The Oasis WCX cartridges for Symbiosis/Prospekt-2 systems are designed for rugged, reproducible, and ultra-fast on-line SPE in the Spark Holland Symbiosis and Prospekt-2 systems. Each cartridge contains 10.4 mg of Oasis WCX, a polymeric reversed-phase, weak cation exchange mixed-mode sorbent that has been optimized for fast, simple, and highly selective sample preparation of strong bases and quaternary amines. Each 800-series tray contains 96 cartridges and can be directly loaded into the Automatic Cartridge Exchange (ACE) or the ACE Feeder units of the Symbiosis/Prospekt-2 systems without the stainless steel tray holder/adaptor.

Waters Corp Sep-Pak Cyanopropyl (CN) 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 50/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 Oasis HLB 3 cc Vac Cartridge, 400 mg Sorbent per Cartridge, 60 µm, 100/pk
The 3 cc Oasis HLB Vac 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.
Waters Corp Oasis MCX Plus Short Cartridge, 225 mg Sorbent per Cartridge, 60 µm, 50/pk
Oasis MCX Plus cartridges contain Oasis MCX is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting basic compounds with cation-exchange groups. Since the Oasis MCX 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. The 60 µm particle size is recommended when working with viscous samples. These versatile Plus Short cartridges can attach easily to pumps and syringes for reliable, positive-pressure flow to speed up the sample processing time. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems.
Waters Corp Sep-Pak C8 Vac RC Cartridge, 100 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 C8 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 37 - 55 µm, 100/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 Accell Plus QMA Carbonate Plus Light Cartridge, 46 mg Sorbent per Cartridge, 40 µm, 50/pk
Sep-Pak Accell Plus QMA Carbonate Plus Light cartridges contain a silica-based, hydrophilic, strong anion-exchanger with a large pore size (300Å) and a carbonate counter-ion. These cartridges are used for extraction of anionic analytes in aqueous and non-aqueous solutions when the chloride counter-ion in the standard Sep-Pak Accell Plus QMA cartridges interferes with the analysis. These Light-style cartridges have a distinctive finned outer body and a reduced internal diameter, which results in an interstitial volume about one-third that of the corresponding Plus-style cartridge. This design allows you to elute fractions in a minimal volume to improve recoveries and reduce solvent consumption, a benefit especially for applications where samples are limited or where excessive dilution is a concern.
Waters Corp Oasis MAX 3 cc Vac Cartridge, 60 mg Sorbent per Cartridge, 30 µm, 100/pk
The 3 cc Oasis MAX cartridges contain the Oasis MAX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting acidic compounds with anion-exchange groups. Since the Oasis MAX 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.
Waters Corp Certified Sep-Pak Alumina N 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 30/pk
Certified Sep-Pak Alumina N Vac cartridges contain a highly active grade of alumina with a neutral 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 neutral alumina is suitable for applications such as synthetic crude oil fractionation. Certified Sep-Pak Alumina N 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.
