SPE Disks and Cartridges
Waters Corp Sep-Pak Alumina N 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 50 - 300 µm, 20/pk
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. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak C8 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 55 - 105 µm, 20/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.
Biotage Pacific Premium Oil & Grease Disk, 47 mm
Pacific Premium disks, available in both 47 mm and 90 mm, offer excellent recovery and precision. Pacific Premium Oil and Grease SPE Disks provide fast flow rates with dirty samples while offering high recovery values for the oil and grease fraction of the sample. These disks blend various diameters of high quality borosilicate glass micro-fibers; the upper surface of each disk provides a greater porosity, essential for handling particulate heavy samples, and the bottom layer, comprised of smaller micro-fibers and packing material, retains the oil and grease fraction.
Waters Corp PoraPak Rxn CX 6 cc Flangeless Vac Cartridge, 400 mg Sorbent per Cartridge, 80 µm, 30/pk
PoraPak Rxn CX is a polymer-based strong cation-exchange resin designed specifically for post synthesis cleanup of reaction mixtures in drug discovery.
Waters Corp PoraPak Rxn CX 60 cc Vac Cartridge, 5 g Sorbent per Cartridge, 80 µm, 10/pk
PoraPak Rxn CX is a polymer-based strong cation-exchange resin designed specifically for post synthesis cleanup of reaction mixtures in drug discovery.
Waters Corp Oasis MCX 6 cc Vac Cartridge, 150 mg Sorbent per Cartridge, 60 µm, 30/pk
The 6 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 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 Oasis HLB 20 cc Vac RC Cartridge, 30 mg Sorbent per Cartridge, 30 µm, 50/pk
These Vac RC cartridge contain the Oasis HLB sorbent, which is a universal polymeric reversed-phase sorbent for 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. These cartridges feature an integral 20 cc funnel-shaped reservoir for convenient processing of greater volumes of samples or solvents. They can be used with robotic sample preparation equipment or with vacuum manifolds.
