SPE Disks and Cartridges
Waters Corp Sep-Pak Vac Cartridge, Silica, 500 mg, 6 cc, 55-105 μm
This cartridge utilizes a polar stationary phase, primarily for adsorbing analytes from non-polar solvents like hydrocarbons, chloro- or fluoro-substituted hydrocarbons, or less polar esters and ethers. Analyte retention can occur via hydrogen bonding, dipole-dipole interactions, or cation-exchange in aqueous samples.
- Designed as a precision chromatographic tool for sample enrichment and purification.
- Contains a polar stationary phase for adsorbing analytes from non-polar solvents.
- Manufactured with high-quality, clean, dry, and reproducible packings.
- Packings offer optimal surface area, pore-size, and particle-size distributions.
- Sealed in a non-contaminating poly-foil pouch to maintain integrity and purity until opened.
- Enables easy sample extraction and preparation and convenient transfer without spillage or evaporation.
Waters Corp Waters Oasis MCX Vac Cartridge, 1 cc, 10 mg, 30 μm
The Oasis MCX 1 cc Vac Cartridge features a novel, mixed-mode polymeric sorbent, optimized for enhanced selectivity and sensitivity in extracting basic compounds. Its water-wettable nature ensures consistent retention and excellent recoveries, even if the sorbent runs dry, simplifying sample preparation. Cartridges are designed for use with vacuum manifolds and automated solid-phase extraction (SPE) instruments.
- Novel, mixed-mode polymeric sorbent optimized for high selectivity and sensitivity in extracting basic compounds with cation-exchange groups.
- Water wettable, maintaining retention and excellent recoveries even if sorbent runs dry.
- Designed for use with vacuum manifolds and automated SPE instruments.
- Enables separation of analytes from complex samples into acidic and basic or neutral compounds.
- Known for greater recovery, repeatability, stronger retention, and selectivity.

Waters Corp Oasis HLB 1 cc Vac Cartridge, 10 mg Sorbent per Cartridge, 30 µm, 100/pk
The 1 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. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Waters Oasis WCX Cartridge, 1 cc/30 mg, 30 μm
The Oasis WCX (Weak Cation eXchange) SPE material is designed for sample preparation of strong bases and quaternary amines. Its retention mechanism is mixed-mode (both ion exchange and reversed phase), which enhances retention for all types of basic analytes, particularly strong bases.
- Designed for sample preparation of strong bases and quaternary amines.
- Utilizes mixed-mode retention (ion exchange and reversed phase).
- Enhances retention for all types of basic analytes.
- Particularly effective for strong bases.
- Format: 1 cc/30 mg.
- Particle size: 30 μm.
- Quantity: 100 per box.
