Title: Controlling the Flow Rate of Many Fluids With Floating Vials In a Pressurizeable Container
Published: November 01, 2009
Abstract: We report a simple strategy to control the pressure-driven flow rates from fluid reservoirs to a microchip in an efficient and compact fashion. We demonstrate that using a floating reservoir, less than 1 percent change in flow rate per ml of delivered volume can be achieved with gravity-driven flow, which is more than 20-fold improvement over a non-floating reservoir. Using this principle, we fabricated a 19-reservoir system to supply fluids to a multi-inlet microfluidic device.
