A hygienic and contamination-free transfer of blood or corresponding fluids from a cylindrical collecting container, such as a test tube, to a pipette is most desirable for instance at determination of the sedimentation rate of the blood corpuscles; the invention concerns a device for accomplishing such a transfer comprising in combination a tube formed pipette of a compressible, transparent material, a cylindrical body designed to cooperate with the interior of the container as a piston/cylinder arrangement; the cylindrical body being provided at one end of the tube and having an axial through hole adapted to allow communication between the tube and the container. |
