Long-term continuous operation ability was demonstrated by 10 h of continuous separation and recovery of hexane from water without a noticeable decrease in efficiency: (a) a circulatory system employed for the demonstration of the consecutive oil collection capabilities of this apparatus and (b) a plot of the flux of oil (n-hexane) versus time with such a system. The voltage for Mini Electric Motor 360 S is 4.5 V, and the inner diameter of tube is 1.5 mm (outer: 2 mm). The volumes of the oil and water are 30 and 150 ml, respectively, in a 250-ml beaker.
