Waters Corp Waters Sep-Pak Cartridge, Cyanopropyl (CN), Vac 3 cc/200 mg, 50/box
The Cyanopropyl (CN) Sep-Pak cartridge is a silica-based Solid-Phase Extraction (SPE) product, known for pioneering sample preparation and being widely referenced. These cartridges are precision chromatographic tools for sample enrichment and purification, offering a 3 mL volume and 200 mg of Cyanopropyl (CN) sorbent, with a hold up volume of 0.42 mL, provided in a 50-count box.
- Offers minimum cost sample preparation.
- Constructed with molded, high purity polypropylene “syringe-barrel” bodies.
- Includes two polyethylene frits to contain the packing material.
- Features a standard male-Luer tip for use with multi-position vacuum manifolds.
- Color-coded printing on the syringe barrels identifies the sorbent type.
Waters Corp Waters Sep-Pak C18 Vac RC Cartridge, 100 mg Sorbent, 55 to 105 μm
These cartridges feature a silica-based bonded phase with strong hydrophobicity, designed to adsorb analytes, even those with weak hydrophobicity, from aqueous solutions. They are suitable for various applications, including the analysis of drugs and their metabolites in biological samples, desalting peptides, detecting trace organics in environmental water, and analyzing organic acids in beverages. Their behavior is similar to reversed-phase HPLC columns.
