A rotor for a centrifuge comprises a bottom part and a top part. The top part is formed with openings for receiving test tubes in rim engagement. The bottom part has an upwardly deformed outer rim, which constitutes a collecting trough. The test tubes are particularly indirectly inserted into the openings (3 to 5) and are biased by spring means (21), which engage the particularly indirectly inserted test tubes from the inside and urges them outwardly against a frustoconical wall (10) of the top part. For an indirect insertion of the test tubes, they may be inserted into guide inserts (6, 7) which consist of cylindrical bushings and are urged outwardly.
