Benchrocker With adjustable speeds and tilt angles, user can set both parameters to match vessel size and volume of liquid being mixed. User can adjust both parameters to match vessel size and volume of liquid being mixed, yielding optimum results. Rocking speed and tilt angle are both easily adjustable in seconds. At low speeds and minimal tilt angles, 2D for "see-saw" motion provides 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. Dual platform option expands workspace. BenchRocker 2D can accept stackable platforms (2.75" clearance). All platform mats are autoclavable. Maintenance free brushless motors and safe for use in cold rooms and incubators.
