Patent ID: 8425862

Claim:
An automated installation for detecting fixation of molecules of biological origin or biomolecules on a sample in three-dimensions, comprising: a plurality of individual containers ( 1 ), each of the containers having an internal empty space for receiving a respective different three-dimensional sample to be treated at a same time, each of the containers comprising a perforated base ( 2 ) and a side wall ( 3 ) defining the internal empty space, the side wall being distinct from and closed by the perforated base ( 2 ) for the continuous passage inside the respective containers of solutions or liquid reagents to be brought into contact with the sample, these containers having the same diametric space requirement and being accommodated in vertical superposition in an external casing positioning and confining the containers, the perforated base comprising a cloth with a mesh size allowing free flow of the solutions or liquid reagents, the cloth being arranged to house and support the respective sample in the respective one of the containers, a circuit ( 50 ) for the continuous flow through the containers ( 1 ) into the casing, under adjustable pressure, of these solutions or liquid reagents, originating from distinct reservoirs ( 17 ), these solutions or liquid reagents being introduced on demand, together or separately into this circuit, a multipath solenoid valve ( 15 ), suitable for separately connecting each respective reservoir ( 17 ) with the circuit ( 50 ), an electric pump ( 13 ) that reverses the pumping and backflow direction and effects continuous circulation in the circuit ( 50 ) of the solutions or liquid reagents taken from the reservoirs, and a sequential and coordinated control and command means ( 22 ) of the pump ( 13 ) and of the multipath solenoid valve ( 15 ), said control and command means being programmed to operate the multipath solenoid valve so as to separately connect each respective reservoir according to a predetermined sequence adapted to conduct fixation of molecules of biological origin or biomolecules on one or more samples within said containers, wherein said circuit ( 50 ) is capable of recycling at least part of one or more of the reagents originating from one or more of said reservoirs.
