Flow-rate, pressure and microfluidic resistance can be approximated by a simple equation, based on the electrical analogy (Ohm’s law). For a given applied pressure, the value of the flow-rate depends on the microfluidic design of the system.
So, as microfluidic designs become more and more complex, the calculation of the required pressure leading to the desired flow rate becomes more and more difficult. The case of coupled multi-channel chip designs for instance can be extremely difficult to address efficiently. The Flow Rate Control Module successfully overcomes these hurdles by predicting and automatically adjusting pressure(s) to reach the flow rate set-point(s).
Indeed, the FRCM (Flow-Rate Control Module) is based on a powerful algorithm that enables the internal modeling of any microfluidic system linking each flow-rate to a combination of pressure orders, whatever the microfluidic design. Thanks to this unique algorithm, the FRCM can predict the pressure values to apply to reach the flow rate set-points.

- As shown in the figure, applying pressure in the FLUIWELL™ reservoirs creates a liquid flow through a microsystem. As both pressures and flow-rates are measured by the MFCS™-EZ and the Flow-Rate Platform, the Flow-Rate Control Module is able to automatically adjust pressure(s) to reach the flow-rate set-point(s). This operating principle enables one to control flow-rates even in complex microsystems made of coupled channels and keep the benefit of pressure actuation.
- The FRCM builds the internal model itself to determinate links between pressure and flow-rate
- Flow-rate set-points are quickly entered in by the user via the MAESFLO™ software. Thanks to the internal model of the microfluidic experiment, the FRCM algorithm automatically calculates and applies the pressures needed to obtain the requested flow-rates.

Yes, the size market at the nozzle are here to help you estimate the size of the droplets you are generating. The Droplet Starter Pack has been designed to have very stable flow-rates, as the microfluidic resistance is mainly within the chip. This means that the flow-rates will stay stable even with pressure control only, thus the droplet sizes.
Because CTCs detection and labelling need a very precise and smooth flow control, Fluigent MFCS™ associated with the Flow-Rate Control Module and the ESS™ platform, was the designated choice to be able to efficiently control the flows of all the solutions and samples. […]
Many microfluidic applications require switching between multiple solutions (such as samples or buffers) while maintaining a constant flow-rate during the course of their experiment. In this application, one MFCS™-EZ pressure channel is connected via a manifold to ten separate vials containing different aqueous solutions. […]
The use of water-in-oil droplets in microfluidics in high-throughput screening is rapidly gaining acceptance. The main application areas currently involve screening cells as well as genetic material for various mutations or activity. Here the aim is to isolate single DNA molecules and analyze the enzymes and proteins resulting from their expression. […]
