An arrangement for placing a separating gel between two phases of different specific gravity located in a sample tube has a container (11) in which a separating gel (16) is accommodated. The container (11) which can be inserted into the sample tube up to the bottom thereof has a closed base (13) and a lid (14) at the top which can be displaced within the container in the manner of a piston. The lid is provided with at least one discharge opening (15) which is small relative to the area of the lid. The specific gravity of the lid (14) is greater than that of the separating gel (15) (FIG 3).

An apparatus for placing a separating gel (16) between two phases of different specific gravity which initially form a dispersion or a suspension in a sample tube (12), said sample tube having a closed bottom and an open or openable top, comprising: a container (11) adapted to hold said separating gel, said container having a closed bottom and an open top and being shaped such that said container can be inserted into said sample tube up to the bottom of said sample tube; and a lid (14) displaced within said container and slidable up and down inside said container, said lid having at least one opening (15, 15′) which is small relative to the area of said lid, said lid having a specific gravity greater than the specific gravity of said separating gel.
