SPE Disks and Cartridges
Waters Corporation Sep-Pak Accell Plus QMA Carbonate Plus Light Cartridge, 46 mg Sorbent, 40 μm, 50 pk
These cartridges feature a silica-based, hydrophilic, strong anion-exchanger with a large pore size (300Å) and a carbonate counter-ion. They are designed for the extraction of anionic analytes from various solutions, especially where chloride interference is a concern.
- Silica-based, hydrophilic, strong anion-exchanger with 300Å pore size and carbonate counter-ion.
- Extracts anionic analytes from aqueous/non-aqueous solutions; avoids chloride interference.
- Light-style format with reduced internal diameter; enables minimal volume elution.
- Improves recoveries and reduces solvent consumption for limited samples.
- Ideal for isolating anionic proteins, acidic pigments, phenolic compounds, and inorganic anions.
- Manufactured in ISO 13485/9002-registered facility, compliant with cGMP for Class 1 Medical Devices.
Waters Corporation Solid Phase Extraction Cartridge, C8, 400 mg Sorbent, 37–55 μm, 50 pk
This Sep-Pak C8 Plus Short Cartridge features a silica-based bonded phase with moderate hydrophobicity. It is designed for methods requiring less retention than C18, making it suitable for applications such as the analysis of drugs and their metabolites in serum, plasma or urine, and peptides in serum or plasma.

- Not water wettable
- pH range of 2 to 8
- Hold up volume of 0.8 mL
Waters Corp Oasis MAX 6 cc Vac Cartridge, 150 mg Sorbent per Cartridge, 60 µm, 30/pk
The 6 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 Waters Sep-Pak tC18 Vac Cartridge, 1 cc, 50 mg Sorbent
The Sep-Pak tC18 Vac Cartridge is a solid phase extraction (SPE) product designed for sample preparation. It features a strongly hydrophobic, silica-based bonded phase with trifunctional bonding chemistry, offering enhanced hydrolytic stability.
- Strongly hydrophobic, silica-based bonded phase.
- Trifunctional bonding chemistry for enhanced hydrolytic stability.
- Reduces solvent consumption and increases recoveries.
- Optimal surface area, pore size, and particle size distributions.
- Packing weight controlled within ±5% for reproducible performance.
- Sealed in a non-contaminating poly-foil pouch.
- Molded polypropylene syringe-barrel bodies with polyethylene frits.
- Standard male-Luer tips for multi-position vacuum manifolds.
- Manufactured in ISO 13485/9002 compliant facilities.
