The adaptability of laboratory centrifuge
because laboratory centrifuge can make two phase liquid rapidly, fully mixing, is highly beneficial for the spread of the extraction material, so for controlled by diffusion factor extraction system, the mass transfer stage efficiency of laboratory centrifuges to achieve more than 90% is not difficult, but for the mass transfer speed is slow of chemical reaction control system of extraction, due to the usual laboratory in contact two phase liquid centrifuge time zero point only a few seconds to 10 seconds, and some necessary chemical reactions in the process of extraction need dozens of seconds and even a few minutes to complete, meet this kind of extraction system, laboratory centrifuge can only get a very low level of efficiency. For this and is suitable for this kind of extraction has been developed specially for the long exposure time of the process of laboratory centrifuges. Two-phase liquid mixture in this laboratory centrifuge contact time can be up to several seconds to several minutes to ensure a high enough level of efficiency, and because of this laboratory centrifuge split phase time did not increase, so the overall level of residence time is shorter. Have long contact time laboratory centrifuge, laboratory centrifuge for the adaptability of extraction system is more common.
