[object Object]

Method of contacting a first and a second immiscible liquids without mixing them, including: (a) the first liquid is placed in at least one container comprising a wall made of a solid material that is non reactive with the first and second liquids, said wall having one or more through-holes and the first liquid being non wetting vis &#xe0; vis said solid material of the wall; (b) said first container is immersed in a volume of the second liquid so that the first liquid is in contact with the second liquid at the level of said through-holes; (c) the first liquid is left in contact with the second liquid for a time sufficient for mass exchange, transfer, to take place between the first and second liquids; and (d) said first container is withdrawn from the volume of the second liquid.
