    • PROBLEM TO BE SOLVED: To facilitate liquid-liquid partitioning or liquid-solid partitioning after centrifugal extraction when extracting a target substance from a substance mixture into a solvent.SOLUTION: An extraction container 3 has a closed-end cylindrical shape, and is rotated around a central axis by an extractor rotor 4 driven by a motor 51. The extraction container 3 includes: an opening 3b provided in a bottom portion thereof; and a valve (valve ball 32) provided at the opening, and opened or closed by a pressure difference between above and below the valve. In extraction, a substance mixture and a solvent are put into the extraction container 3. The extraction container 3 is repeatedly subjected to normal rotation, pausing, reverse rotation, and pausing to thereby extract a target substance from the substance mixture into the solvent and to separate the liquids into upper and lower layers. Then, an air pressure hose nozzle is connected to an opening 31b in an upper portion of the extraction container 3, and an inside of the extraction container 3 is pressurized to open the valve at the bottom portion. Thus, the liquids are sequentially discharged from the liquid in the lower layer.
    • 要解决的问题:当将物质混合物中的目标物质提取到溶剂中时,有利于离心萃取后液 - 液分配或液 - 固分配。 解决方案:提取容器3具有封闭端圆筒形状,并且通过由马达51驱动的抽出器转子4围绕中心轴线旋转。提取容器3包括:设置在其底部的开口3b ; 以及设置在开口处的阀(阀球32),并且通过阀上方和下方之间的压力差打开或关闭。 在提取时,将物质混合物和溶剂放入提取容器3中。提取容器3重复进行正常旋转,暂停,反转和暂停,从而将物质混合物中的目标物质提取到溶剂中, 将液体分离成上层和下层。 然后,将空气压力软管喷嘴连接到提取容器3的上部的开口31b,并且提取容器3的内部被加压以在底部打开阀。 因此,液体从下层的液体中顺次排出。 版权所有(C)2012,JPO&INPIT
