Popis: In present work, two piezo actuated cantilever beams are connected to a glass tube setup. The glass tube arrangement consists of the vertical tubes inserted in the liquid solutions, connector tubes, a glass bulb, and a helical tube, and it acts as a pump and mixer. When the piezo actuators are energized by AC voltage, vertical tubes start pumping the solution. At whatever point the two different solutions are in contact with each other in vibrating glass bulb and helical tube, mixing occurs. The proposed technique is a combination of active and passive mixers in which the liquid pumping action is utilized for fluid mixing. The diverse flowrates acquired at 65, 75, and 80 Vp-p are 0.038, 0.05012, and 0.06976 mL/s. UV-vis spectrophotometer tests mixed solutions for mixing performance. The important findings are, mixing performance depends upon two parameters, viz. solution concentration and flowrate.
