The SHEL LAB Large Capacity Shaking Incubators have a greater load capacity than other SHEL LAB incubators. They can shake between 30-400 RPM with a smooth, quiet motion. The door opens easily with hydraulic pistons to facilitate loading and unloading. The universal shaker platform accommodates a wide variety of flask clamps, test tube racks, and microtiter plates. Four load-bearing positions provide optimal weight distribution and support heavy loads over time. An adjustable, counter-balanced weighting system allows for off-center and varying capacity loads.
