摘要： A device for separating the liquid and solid constituents in a chemical reaction medium (1), comprising a metal filtering needle (12) with lateral holes (5) able to pass through polymer- or rubber-like membranes without losing their impermeability to gas (2), a source of suction (7) able to draw liquid out of an enclosed space (8), a channel for evacuating liquid (6) and an end piece (4).
