The DMQ lab mill is a versatile, 1/2-liter, tank-sized mill that can be used in continuous as well as circulation modes. Ring screens can be easily adjusted to accommodate the use of grinding media from 1mm to as small as .3mm. The DMQ-05 utilizes Delta discs, a proprietary design that eliminates shaft whip and mill vibration, while providing much greater random media motion for improved milling efficiency. Call 330/929.3333
