W.S. Tyler has been manufacturing the Ro-Tap® Test Sieve Shaker since 1917. Throughout the years, the look has changed but its simple operating design remains the same.  The Ro-Tap’s rotating and tapping mechanical movements have not changed year-to-year, decade-to-decade.

 

Dry Particle Analysis with Tyler Test Sieve Shakers is always consistent and repeatable!

 

W.S. Tyler offers a complete line of shakers including the affordable course sive shakers, the traditional Ro-Tap® Models and our exciting new machine, the Ro-Tap E.
