Microfluidic platforms rely on the ability to guide and spread liquids in channel and chamber structures. Phaseguides – ridges protruding from the channel bottom or top – have proven successful to achieve controlled filling and can also be used for passive valving. We present an experimental investigation of the burst/overflow pressure of water in 90° phaseguide in an injection moulded polymer chip as function of the phaseguide height, h. Phaseguide structures without and with branches of angles α = 45°, 60° and 75° were studied. The knowledge obtained in this study provides a set of systematic experimental data to compare with simulations/theory.
