The Burrell Wrist-Action Shaker has been modified to meet the requirements for Simethicone Testing as described in the current edition of the U.S. Pharmacopoeia.  The testing specifies, a shaking radius (as measured from  the center of the shaft to the center of the bottle) of 13.3^+-0.4cm, an arc travel of 10 degrees at a frequency of 300 +-10% oscillations per minute.  Burrell redesigned the mechanics of The Wrist-Action's Shaker and when this redesigned unit is equipped with the Burrell Side-Arm Extension Clamps (not included in this listing but easily found online) the performance requirements for the Simethicone Foaming Solution Test are achieved.  These standards are met without compromising the Wrist-Action Shakers outstanding features.   

The Simethicone Shaker Side Arm extension clamp can be found online, not included in this listing. The Burrell Side-Arm Extension Clamp holds up to a 3" diameter Container.  As these clamps attach to adjustable extension rods which are inserted into the Side-Arm Shaft the Vessels can be precisely positioned at the required radius setting. A quick adjustment allows easy repositioning of the rod with the Clamp.

Controlled Adjustment:
The Position of the Lever Arm (setting of 6 ) is critical in the performance of the Foaming Solution Test, as it establishes the shaking amplitude and speed.  Burrell Scientific has developed a simple, but very effective tool for maintaining the position of the Lever Arm.  Once the Lever Arm is set at the proper position , a notched locking tool is inserted into place holding the Lever Arm firmly in position.

Ready to Operate:
The Burrell Wrist-Action Simethicone Shaker is shipped ready-for-use out of the carton.  Plug the unit into a properly grounded 3-prong , 110 to 120 Volt, AC power source. Firmly grip the owner-supplied vessels with the Clamps (clamps not included in this listing), move the Lever Arm to the proper position to start mixing, slip the notched locking tool into position set the timer and begin operations.
