This 3D rocker is designed to provide the precise speeds and tilt angles required for a broad range of molecular and biological mixing applications. The user can adjust both parameters to match the vessel size and the volume of liquid being mixed, yielding optimum results. The rocking speed and tilt angle are both easily adjustable in seconds. At low speeds and minimal tilt angles, both models (2D for “see-saw” motion or 3D for “gyratory” motion) provide a gentle wave effect for non-foaming mixing, as is required for most blot washing and gel work. When set to higher speeds and more extreme tilt angles, they produce aggressive agitation for vigorous sample mixing. This rocker can accept stackable platforms (clearance = 2.75 in.). All platform mats are autoclavable. It has maintenance free brushless motors and are safe for use in cold rooms and incubators.
