Sep-Pak Alumina A Classic Cartridge, 1850 mg Sorbent per Cartridge, 50-300 µm, 50/pk

Alumina Sep-Pak A Classic cartridges have an acidic surface chemistry and a highly active grade of alumina. The aluminum oxide surface is very polar and exhibits Lewis acid characteristics, making it the ideal lab equipment for analyte retention. This normal phase sorbent is identical to silica in terms of application; however, it is slightly more stable under high pH circumstances than non-functionalized silica. In aqueous conditions, this acidic alumina also functions as a low-capacity ion exchanger. This sorbent, unlike polymer-based ion exchangers, is unaffected by high-energy radioactivity and can be utilized to isolate radioactive compounds. These Classic-style cartridges are designed to be used with a Luer-tip syringe for positive displacement and may also be simply attached to vacuum-assisted flow devices using a male/male adaptor.

Add the Sep-Pak Alumina A Plus Classic Cartridge to your lab for easy extraction and convenient transport of solvents, solutions, and samples without worrying about spillage or sample loss due to evaporation. For sample enrichment and purification, the lab equipment is a dependable and exact chromatographic tool.

All Sep-Pak cartridges and plates are manufactured in an ISO 13485 and ISO 9002-registered facility in compliance with cGMP guidelines for the U.S. Food and Drug Administration for Class 1 Medical Devices.
