Disposable high pressure peristaltic micro pump for standalone and on-chip applications

Abstract

A novel disposable high pressure peristaltic micro pump has been developed, which allows a precise dosing of single volumes in the nanoliter range. The tube is integrated into a single use cartridge, which offers numerous advantages. A high pressure can be generated, while a small internal volume gives opportunity to handle expensive or rare fluids. Its small size allows the implementation into biochips or micro fluidic systems. The standalone solution can be connected to semi flexible tubes or pipes. The fluidic properties of the pump and the achievable maximum pressure have been determined. The fatigue resistance of the cartridge has been verified. Its simple structure offers the potential for mass production.
