Reproduce the rotating and tapping motion of hand-sieving but with more uniform motion for highly reproducible results
Shakers are actuated by a built-in, 99-minute digital timer with 0.1 second accuracy. They are powered by a 1/4 hp motor and include a 5-ft cord (110 VAC models also include U.S. three-prong plug).
Ro-tap II Sieve Shakers double your shaking capacity while maintaining the accuracy of a single mechanical shaker. Units hold up to twelve full-height sieves or twenty-six half-height sieves.
