SPE Disks and Cartridges
Waters Corp Sep-Pak tC2 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 37 - 55 µm, 30/pk
Silica-based bonded phase with low hydrophobicity character; use for methods requiring less retention than C8; applications are similar to C18 and C8.
Waters Corp Sep-Pak Florisil 35 cc Vac Cartridge, 10 g Sorbent per Cartridge, 50 - 200 µm, 10/pk
Polar, highly active, weakly basic sorbent for adsorption of low to moderate polarity species from nonaqueous solutions.
Waters Corp Oasis MAX 3 cc Flangeless 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. The flangeless configuration allows the cartridges to be closely packed for processing in specialized automated SPE systems.
Waters Corp Oasis MAX 1 cc Flangeless Vac Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 cc flangeless 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.

Waters Corp Sep-Pak tC2 1 cc Vac Cartridge, 100 mg Sorbent per Cartridge, 37 - 55 µm, 100/pk
Silica-based bonded phase with low hydrophobicity character; use for methods requiring less retention than C8; applications are similar to C18 and C8.
Waters Corp Sep-Pak Alumina N Classic Cartridge, 1850 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina N Classic 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. These Classic-style cartridges are designed for use with positive displacement by a Luer-tip syringe and can also attach easily to vacuum-assisted flow devices using a male/male adaptor.
Waters Corp Sep-Pak Alumina B Classic Cartridge, 1850 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina B Classic 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 Classic-style cartridges are designed for use with positive displacement by a Luer-tip syringe and can also attach easily to vacuum-assisted flow devices using a male/male adaptor.
Waters Corp Oasis MCX 1 cc Vac Cartridge, 30 mg Sorbent per Cartridge, 60 µm, 100/pk
The 1 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 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.
