W.S. Tyler RO-TAP® RX-812
Designed for coarse testing applications, the affordable RX-812 Coarse Sieve Shaker has the unique capability of using both 8″ diameter and 12″ diameter test sieves simply by using the quick-change adapters provided. Using a singular oscillating motion, the RX-812 has a quiet operation that produces consistent, accurate results.
Designed for dry, free-flowing material, the RO-TAP RX-812 is not recommended for analysis with particles 150 micron (100 mesh test sieves) and coarser.
- Designed for use with 8″ and 12″ diameter Test Sieves.
- For analysis of particles US #100 (150um) and larger
- Oscillating movement only.
- Supplied with adaptor for 8″ and 12″ Test Sieves.
- Oscillations per Minute: 280 (60Hz); 231 (50Hz).

Experience Unmatched Lab Performance With A RO-TAP
Two-Dimensional
Both the RO-TAP RX-29 and RX-30 utilize a horizontal, circular motion alongside brute force hammer taps. This allows particles to stratify and pass through your test sieve stack.
Accurate Results
The RO-TAP name has become the gold standard of test sieve analysis. How? By providing the most accurate and repeatable particle analysis testing results.
Seamless Maintenance
The components of the RO-TAP RX-29 and RX-30 are fabricated from materials designed to minimize maintenance. These parts are easily accessible, reducing downtime.
