The Model 95 Wrist Action® has all the same great features as our Model 75 plus includes variable speed. The Shaker has a variable speed motor which will oscillate from 0 to 450 oscillations per minute. The Shaker has a built in timer to operate from 1 to 60 minutes or can be set to continuous operation. The Burrell Scientific Model 95 is the only true variable Wrist Action® Shaker that duplicates the swirling action of hand mixing. The Wrist Action® Shaker is designed to maintain a constant swirling action as long as required for almost any laboratory application. The adjustment arm controls the amplitude and agitation of shaking from 0 to 15 degrees arc. Flexibility and versatility is what makes the Burrell Shakers so popular. Burrell calls it The Build –Up System. This system allows you to meet your current laboratory needs today and into the future. Beginning with the basic model AA Shaker you can simply add or modify to increase capacity as needed.
