The vortex Multi Reax (Heidolph) allows the shaking of 12 (Ø = 16-32 mm) and 26 (Ø = 10-16 mm) tubes (Falcon or Greiner) simultaneously, increasing the throughput of the laboratory. The rotational speed can be adjusted between 150 and 2000 rpm and it includes a timer to enhance the repeatability of the extraction processes.
