open air shakers are typically designed to suit , researchers application demands in cultivating microbial, tissue cultures and cell cultures. The constant agitation with uniform amplitude provides the optimum oxygen transfer to the cultures, resulting in better and homogenous yield.Ergonomically designed with minimal footprint,Triple-eccentric counterbalanced drive for uniform agitation with 25.0 mm shaking orbit.Precise shaking speed control with gentle start /stop cycle , preventing spillage.
