The inventive device for fast vibration of tubes (24) containing samples, for example biological samples comprises a platform (22) for supporting the tubes and concentric bearing blocks (28, 30) for arranging the platform in a crown (26) which is elastically suspended on a frame (10). Said bearing blocks comprise two rolling bearings arranged one inside the other. Said invention makes it possible to exposed the samples containing tubes to an alternate curvilinear and high frequency motion. |
