The industry standard in test sieve shakers, W.S. Tyler's Ro-Tap® has a unique two-dimensional operation: a horizontal, circular motion and a vertical, tapping motion. This special action allows material particles to stratify and 'seek' critical openings in the test media. This unit provides the most accurate and consistent particle analysis testing.
