Development of a Test Facility for Microfluidic Characterization of Glaucoma Drainage Devices.

Microfluidic characterization plays an outstanding role in the development of glaucoma drainage devices. Here, we describe the optimization of an existing test facility with regard to measurement of small volumetric flow rates in the range of 1 μl/min to 40 μl/min in a minimized testing time. The existing test facility is extended by a flow sensor and validated by microfluidic characterization of glass capillaries. Finally, two micro-mechanical valve prototypes are successfully analysed with regard to opening and closing pressure.
