A fluid flow controller for introducing fluids into a microfluidic device is provided. The fluid flow controller comprising, at least one high resistance fluid pathway provided between an inlet port and a connection port; at least one low resistance fluid pathway between the inlet and connection port; and at least one valve configured to enable fluid flow through the high resistance fluid pathway, the low resistance fluid pathway or both.

Fluid flow controller for microfluidic devices

A device for controlling a fluid flow in an array of fluid pathways on a microfluidic chip is provided. The device comprising: two or more resistors provided upstream of the chip wherein each upstream resistor is configured to provide a resistance at an upstream end of a fluid pathway; two or more resistors provided downstream of the chip wherein each downstream resistor is configured to provide a resistance at a downstream end of a fluid pathway, wherein the values of the resistances are selected in order to control a proportion of fluid that flows through each fluid pathway.

Flow balancing

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.
