WAT051810 - Sep-Pak Alumina N Classic Cartridge, 1850 mg Sorbent per Cartridge, 50-300 µm Particle Size, 50/pk

Part Number: WAT051810

Sep-Pak Alumina N Classic 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 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.
