SKU: WAT051800 Sep-Pak Alumina A Classic Cartridge, 1850 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina A Classic cartridges contain a highly active grade of alumina with an acidic 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 acidic alumina is also low-capacity ion exchanger in aqueous media. Unlike polymer-based ion exhangers, this sorbent is unaffected by high-energy radioactivity and can be used for radioactive compound isolation. 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.
氧化铝Sep-Pak A 经典滤芯具有酸性表面化学特性和高活性氧化铝等级。氧化铝的表面极性很强，表现出路易斯酸的特性，使其成为理想的实验室设备，用于保留分析物。这种正相吸附剂在应用方面与二氧化硅相同；但是，在高pH值情况下，它比非功能化二氧化硅略微稳定。在水溶液条件下，这种酸性氧化铝还可作为低容量的离子交换器使用。这种吸附剂与基于聚合物的离子交换器不同，不受高能放射性的影响，可用于分离放射性化合物。这些经典风格的滤芯被设计为与Luer-tip注射器一起使用，用于正排量，也可使用公/母适配器简单地连接到真空辅助流动设备上。
将Sep-Pak 氧化铝A Plus 经典滤芯添加到您的实验室中，可以轻松提取和方便运输溶剂、溶液和样品，而不必担心溢出或蒸发造成的样品损失。对于样品富集和纯化，该实验室设备是一个可靠的、精确的色谱工具。
