SKU: WAT054625 Sep-Pak Alumina B 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 50 - 300 µm, 20/pk
Sep-Pak Alumina B Vac cartridges contain a highly active grade of alumina with a basic 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 basic alumina is also low-capacity ion exchanger in aqueous media. Sep-Pak Alumina B Vac cartridges can be used to extract phospholipids, steroids, and catecholamines. Since Sep-Pak Alumina B is unaffected by high-energy radioactivity, these cartridges can be used for radioactive compound isolation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
透过将Sep-Pak氧化铝B 12 cc 真空滤芯添加到您的实验室中，可以轻松提取和方便转移溶剂、溶液和样品，而不必担心溢出或蒸发导致的样品损失。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。
Sep-Pak 氧化铝B 12 cc 真空滤芯是由具有基本表面化学性质的高活性氧化铝组成。氧化铝的表面极性很强，表现出路易斯酸的特性，使其成为分析物保留的理想选择。尽管这种普通相吸附剂的使用方式与二氧化硅相同，但在高pH值情况下，它比非功能化二氧化硅略微稳定。此外，在水性条件下，这种碱性氧化铝是一种低容量的离子交换器。由于Sep-Pak 氧化铝B 12 cc 真空滤芯不受高能放射性的影响，因此放射性化学隔离是实验室设备的一个重要用途。
由于 Sep-Pak 氧化铝B 12 cc 真空滤芯密封在一个专门设计的无污染塑料袋中，在实验室打开包装之前，该袋可保持产品完整性、无包装活性和纯度，您可以放心订购。您可以透过我们的在线商店购买实验室设备。
