SPE Disks and Cartridges
Waters Corp Oasis WCX 6 cc Vac Cartridge, 150 mg Sorbent per Cartridge, 30 µm, 30/pk
The 6 cc Oasis WCX cartridges contain the Oasis WCX sorbent, which is a polymeric reversed-phase, weak ion exchange mixed-mode sorbent that has been optimized for fast, simple, and highly selective sample preparation of strong basic compounds and quaternary amines. Since the Oasis WCX 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 Oasis MCX 1 cc Flangeless Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc flangeless Oasis MCX cartridges contain the Oasis MCX, which 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 flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
Waters Corp Oasis PRiME MCX 3 cc Vac Cartridge, 60 mg Sorbent per Cartridge, 30 µm, 100/pk
Oasis PRiME MCX 3 cc Vac Cartridge, 60 mg Sorbent per Cartridge, 30 µm, 100/pk
Hach Company Prefilters, Polypropylene, 90 mm, 25/PK
Xenosep brand ValuSep™ SPE Filters for EPA Method 1664A are designed to provide high recovery and low blank values in Horizon SPEDEX and SPE Manifold applications. Chemically treated with a proprietary reverse phase adsorbent, single layer borosilicate glass ValuSep™ SPE Filters (47mm) can filter the 40 mg/L EPA PAR standard in approximately 10 minutes with significantly faster filtration times for 1 L NPDES-type samples. ValuSep™ SPE Filters offer high recoveries and low blanks at a great price.
Waters Corp Oasis MCX 20 cc Vac Cartridge, 1 g Sorbent per Cartridge, 60 µm, 20/pk
The 20 cc Oasis MCX cartridges contain the Oasis MCX, which 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 syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Oasis MAX 3 cc Vac Cartridge, 60 mg Sorbent per Cartridge, 60 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. The 60 µm particle size is recommended when working with viscous samples. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.

Waters Corp Sep-Pak Alumina B Plus Long Cartridge, 1710 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina B Plus Long cartridges contain a highly active grade of alumina with a basic 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 basic alumina is also low-capacity ion exchanger in aqueous media. Sep-Pak Alumina B Vac cartridges can be used to extract phospholipids, steroids, and catecholamines. Since Sep-Pak Alumina B is unaffected by high-energy radioactivity, these cartridges 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 Florisil 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 200 µm, 30/pk
Florisil is an extremely polar sorbent that is a blend of magnesium oxide and silica gel. This highly active and weakly basic sorbent is used to adsorb low to moderate polarity species from nonaqueous solutions. Florisil is commonly used for pesticide analysis in many AOAC, EPA, and JPMHLW regulated methods for food and environmental samples.
Waters Corp Sep-Pak Florisil 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 50 - 200 µm, 20/pk
Polar, highly active, weakly basic sorbent for adsorption of low to moderate polarity species from nonaqueous solutions.
Waters Corp Sep-Pak Florisil Plus Long Cartridge, 910 mg Sorbent per Cartridge, 50 - 200 µm, 2000/pk
Polar, highly active, weakly basic sorbent for adsorption of low to moderate polarity species from nonaqueous solutions.
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.
