Alsto Ro-Tap® Sieve Shaker & Accessories


W.S. Tyler Test Sieve Shakers were designed for functional use, providing reliable,
accurate and consistent particle analysis service. The units require little maintenance and all operate on 110 or 220 voltage. Each unit is serialized, allowing for complete
traceability. The Ro-Tap®, first produced in 1917, remains the “industry standard” in
many industries
