More than a stir plate, the Wiggler is a programmable eight position stirrer compatible with the impellar-free LeviTube. Each of the magnetic drive positions can be programmed for continuous or intermittent stirring and the small footprint frees up valuable incubator space. The Wiggler’s two-way action, and namesake, gently mixes the LeviTube contents while avoiding unidirectional shear. Even better, the LeviTube’s simple two piece design makes for an affordable disposable bioreactor.
