Powerful “rare earth” magnet automatically pulls stir bar into position and stays coupled even under the most demanding stirring conditions. Stirrer can handle many applications that previously required an overhead mixer. Accommodates stir bars up to 3" in length; order separately. Rugged ABS plastic top plate and heavy-duty motor provide years of reliable service. Trough on housing funnels spills away from electronics and speed control knob. Stirrer features non-skid rubber feet; includes a 6-ft power cord with U.S. standard plug. Order glass, stainless steel, or polypropylene solution bottles separately.
