Test Sieve Shakers:

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.

Available Models:

• The RX-29 model is designed for testing with 8″ diameter test sieves;
• The RX-30 model is designed for testing with 12″ diameter test sieves.
• The RO-TAP® Electronic Test Sieve Shaker operates with 8” or 12″ diameter Test Sieves and offers precise sieving results.
• The compact, RO-TAP RX-29-E (8″ Test Sieves) unit requires minimal space on a laboratory countertop.
• The RO-TAP RX-30-E (12″ Test Sieves) model is a floor unit. Controls can be remotely mounted for convenient operation. The units are designed for light to medium testing applications.
• The RX-94 Test Sieve Shaker utilizes the same traditional design as the RX-29 model. In addition, the unit features a cavity that allows for two “stacks” of 8 in. or 200 mm diameter test sieves.
• The RX-812 coarse sieve shaker has the unique capability of using both 8 in. and 12 in. diameter test sieves
