Burrell 00 Wrist-Action Shaker

The Burrell 00 wrist-action shaker is designed to oscillate at 385 oscillations per minute, plus or minus 5%. The action of the shaker imitates the back and forth action of the human wrist and the lever arm adjusting lever can achieve an action from a gentle swirl to a violent agitation depending on the angle of movement. A timer located at the center of the control panel allows for either continuous operation or pre-set timed operations of up to 10 minutes.

This unit is in good working order and can accommodate 4 flasks - as seen in photos.
