A device for filtration of fat extracted during liposuction procedures. The device includes: a first reservoir filled with a physiological solution adapted to be suctioned by a syringe containing fat mixed with blood and anesthetic a second reservoir, empty, intended to receive cyclically from the syringe a liquid mixture consisting of the suctioned solution, blood and anesthetic separated from the fat and at least one filter element provided with a connection member for connection of the syringe, the filter element being connected to the first reservoir and the second reservoir through a three-way connector. A first one-way valve configured to allow passage of a flow of fluid from the first reservoir towards the connector is arranged on a branch of the connector connected to the first reservoir. A second one-way valve configured to allow passage of a flow of fluid from the connector towards the second reservoir is arranged on a branch of the connector connected to the second reservoir.
