A device for mixing immiscible or semi-immiscible liquids and subsequently separating one or more of them followed by transfer is disclosed. An array of elements is utilized with the center decant transfer tube of one element connecting with the mixing tube of the adjacent element to the right. This is used for transfer of the upper phase material, generally known as the effluent phase. Transfer of the lower phase or the residual phase is accomplished by transferring to the mixing tube indicated to the left in the array. The upper phase is first decanted through a center decant tube, and then, prior to mixing, the lower phase is transferred. The sequence of transfer can be reversed if the units are stacked so that movement proceeds in opposite directions in adjacent rows of elements. The lower phase transfer tube is purposefully canted downward, and a two-speed rotation motor may be used in order to convert the system from a counter-double-current distribution system to a standard counter-current distribution device. This is accomplished by quickly passing the lower phase decant, thereby retaining the lower phase in the same tube.
