由集成垂直毛细管组成的被动泵已被开发用于微流控芯片，作为具有优异流量和流速的有用组件。通过将所有毛细管的底部连接到由微流体芯片中的薄层通道组成的顶表面来使用内置于无源泵中的流体芯片，其中薄层通道深度小于毛细管半径。结果，垂直毛细管协同而不是独立地抽吸流体，从而在每种情况下都发挥最大的抽吸效率。这意味着实现了表现出很小变化并且没有任何外部动力或操作的流速。内置于该被动泵中的微流体芯片具有实现准稳定而不是快速降低的流速的能力，这是普通毛细管中的通用流动特性。
A passive pump consisting of integrated vertical capillaries has been developed for a microfluidic chip as an useful component with an excellent flow volume and flow rate. A fluidic chip built into a passive pump was used by connecting the bottoms of all the capillaries to a top surface consisting of a thin layer channel in the microfluidic chip where the thin layer channel depth was smaller than the capillary radius. As a result the vertical capillaries drew fluid cooperatively rather than independently, thus exerting the maximum suction efficiency at every instance. This meant that a flow rate was realized that exhibited little variation and without any external power or operation. A microfluidic chip built into this passive pump had the ability to achieve a quasi-steady rather than a rapidly decreasing flow rate, which is a universal flow characteristic in an ordinary capillary.
