The ROSS Model DPM-40 Double Planetary Mixer has been reconditioned for vacuum operation with stainless steel type 316 wetted parts (heavy-duty Rectangular Blades, jacketed mix vessel and vacuum hood) and updated touchscreen controls. A motorized lift raises the vessel to the mixing position, an arrangement that ensures uniformity of blade-to-vessel clearances even if the installation floor is not completely level. ROSS offers reconditioned mixers like the DPM-40 for rental or purchase. Various laboratory and production models are available.
