Rugged Rotator

Variable speed adjusts mixing action from a gentle slosh to rapid agitation. Driven by a continuous-duty motor, it can stand up to demanding schedules and long hours of operation. Some of the procedures it can be used for are embedding electron microsocopy, tissue-culture specimens, blood cell suspensions, washing of precipitates, disintegrating tablets, extracting, dissolving slow-reacting samples, homogenizing blood solids with plasma, and rotating closed containers for dialysis bags. A unique clamping device utilizes leverage to assure selected motor position and permits positioning of the motor at any point within a 110° arc. Containers remain visible during rotating. Sturdy, stable, well-balanced, compact base handles substantial loads. Cord-attached speed control module allows convenient placement to avoid danger when starting or stopping rotation. Furnished complete with test tube head and 31 spring clips to accommodate 10mm to 18mm tubes and 16 spring clips to accommodate 20mm to 30mm tubes.
