The Orbis shaker is a compact choice of microplate shaker for any test environment. With a footprint marginally larger than that of the microplate it shakes, the Orbis offers the most economical and advanced solution for your shaking applications. The counter-balanced orbital movement guarantees a stable, quiet and long life operation. The Orbis shaker can be operated as a stand alone unit or alternatively, be easily integrated into a robotic system, with a remote on/off control. Both Orbis shakers can operate as microtube shakers when used with an accessory tube platform. This 131x90mm platform accommodates 40 tubes with diameters 10.5 to 12.7mm.
