    • A reusable liquid chromatographic column consists of three parts, a column body with an integral outlet port molded on one end, a sealing insert with an inlet port, and a perforated cap providing downward force to compress the sealing insert into the column body. A wedge-like seal is employed to seal the connection between the sealing insert and the column body. Two filters on both ends of the column body are used to prevent escape of packing materials from the column chamber under pressure. Hand tightening is adequate to seal the connection by screwing the perforated cap onto the column body. The column is reusable due to its simple disassembling and reassembling processes. It is also disposable due to its inexpensive fabricating materials and manufacturing process.
    • 可重复使用的液相色谱柱由三部分组成,柱体具有在一端模制的整体出口端口,具有入口端口的密封插入件和提供向下的力以将密封插入件压缩到柱体内的穿孔盖。 采用楔形密封来密封密封插入件和柱体之间的连接。 使用柱体两端的两个过滤器来防止包装材料在压力下从柱室逸出。 手拧紧足以通过将多孔盖螺栓拧到柱体上来密封连接。 该列由于其简单的拆卸和重新组装过程而可重复使用。 由于其廉价的制造材料和制造工艺,它也是一次性的。
