A single-layer valve is provided. The valve comprises a microfluidic pathway at least partially defined by a flexible membrane which is configured to deform when subjected to an actuation torque, and a discontinuity bounded by a first surface. The length of the discontinuity is constant across the full width of the first surface. The valve is configured such that the actuation torque on the membrane is larger in a first direction than a second direction substantially opposite to the first direction.

Valves for microfluidic devices

A fluidic system is provided. The system comprises: a rigid housing (), a plurality of flexible reagent containers () contained within the housing (); wherein each reagent container () has a connection port () through which a reagent can flow, in use, on the application of pressure. The system further comprises a single pressure source () configured to apply pressure to the interior of the rigid housing (); a microfluidic device configured to analyse one or more fluids provided from the plurality of reagent containers; and a plurality of channels () configured to transfer fluid from the plurality of reagent containers () to the microfluidic device. The ratio of resistances provided by a combination of the connection ports and the plurality of channels dictates the ratio of flow rates of the reagents. The claimed system allows for an accurate control of the various reagent flow rates while minimizing fluctuations in the relative flow rates.
