A brushless DC motor delivers 40 Ncm of torque across 30–2,200 rpm and handles viscosities up to 10,000 mPas. Speed and run time are set and displayed on an LCD. The keyless feed-through chuck grips shafts of 0.5–10 mm, and the stirrer comes with a support stand, mounting hardware and a 4-arm stainless steel propeller (IPS2050-P-S4).
