SPE Disks and Cartridges
Waters Corp Sep-Pak tC2 Plus Light Cartridge, 145 mg Sorbent per Cartridge, 37 - 55 µm, 50/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 tC2 Plus Short Cartridge, 400 mg Sorbent per Cartridge, 37 - 55 µm, 50/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 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 Oasis HLB 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 60 µm, 30/pk
The 6 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. 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 HLB 12 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 60 µm, 20/pk
The 12 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. 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 A Classic Cartridge, 1850 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina A Classic 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 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.
