An installation for forming a compact film of particles on a surface of a carrier fluid, including: a zone acting as a reservoir of carrier fluid; an inclined ramp; a particle storage and transfer zone situated extending from the inclined ramp; a mechanism moving the fluid; a mechanism dispensing the particles in solution, configured to dispense the particles at the surface of the carrier on the surface of the carrier fluid in the zone acting as a reservoir; and a mechanism raising a level of the carrier fluid by capillary effect, arranged at a junction between the zone acting as a reservoir and the inclined ramp.
