Sep-Pak Alumina N Cartuccia classica | 1850 mg Sorbente per Cartuccia | 50 - 300 µm | 50/pk | 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.
