The industry standard in test sieve shakers, WS 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. The result is the most accurate and consistent particle analysis testing.

The RX-29 model is recommended for testing with 8" diameter test sieves; the RX-30 model is recommended for testing with 12" diameter test sieves.
