Fluid recirculation for cell perfusion with reduced shear stress
Many microfluidic applications require expensive solutions to be injected at a controlled flow-rate into a microfluidic system, such as cell cultures, PCR processes, cell injections or simulation of blood capillaries with a controlled minimal mechanical stress.
In this application, two MFCS™-EZ pressure channels are connected to two vials containing a physiological buffer for instance. The use of the L-SWITCH™ and ESS™ Control software allows for recirculation between the two vials while maintaining a continuous unidirectional flow-rate within the cell culture chamber.

- High stability
- Flexible automation
- Pressure and/or flow-rate control and limit
Materials needed
- 1 MFCS™-EZ
- 1 L-SWITCH™

SEQUENTIAL FLUID INJECTION & DELIVERY WITH PULSE-FREE FLOW
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. […]
AUTOMATED RARE CELLS CAPTURE AND LABELLING
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. […]
