Abstract: The valve is formed in a valve body housing a first path portion, a second path portion, and an coupling zone between the first and second path portions. A shutter is arranged in the coupling zone and has a shutting portion of ferromagnetic material that is deformable under the action of an external magnetic field between an undeformed position, wherein the shutter closes the coupling zone, and a deformed position, wherein the shutter at least partially frees the coupling zone. The shutting portion of the shutter is formed by a rubber membrane incorporating particles, for example of ferrite particles.

Abstract: A sample treatment and molecule analysis cartridge is configured to be mounted in a treatment machine vertically. The cartridge has a sample inlet opening, a fluidic inlet, and a fluidic outlet. The cartridge houses an extraction chamber extending vertically from the sample inlet opening and connected to the fluidic inlet; a waste chamber extending vertically, alongside the extraction chamber; and a collector extending along the extraction chamber and the waste chamber and having a smaller height than the extraction chamber and the waste chamber. A fluidic circuit connects together the extraction chamber, the waste chamber, the collector, the fluidic inlet, and the fluidic outlet, and is configured to connect the fluidic outlet to vent openings of the extraction chamber, the waste chamber, and the collector, and to connect the bottom end of the extraction chamber to the fluidic inlet, the waste chamber, and the collector.
