Need shaker

I am interested in purchasing a robotic arm that would have the following performance criteria:
I am looking for an arm that can grip a 100ml glass graduated cylinder (diameter=32mm) filled with 100mL of water (Mass~0.7lbs). I would like it to move a distance of 8 inches up, then 8 inches down, at a radius similiar to a human arm (12-16"). I would like this to happen at a rate of 2-3 strokes/sec for a 2.0min time period, then stop.
What are the least expensive existing products that you have that might have that performance?
