Ro-Tap Sieve Shakers is a sieving machine that is widely accepted in standardized particle sizing test methods. The Ro-Tap generates 278 oscillations and 150 taps per minute as specified in some ASTM and other sieving applications. These shakers have a horizontal, circular motion with a vertical tapping action to assure accurate and consistent particle analysis testing results.
These rugged test sieve shakers are built for heavy-duty use and can be bolted to a solid table or sturdy benchtops for stable operation. All models feature a powerful 1/4hp motor for performing consistent particle analysis testing, an adjustable plate sieve support, and a built-in 99-minute x 0.1-second digital timer.
SS-30 8in Ro-Tap® Sieve Shaker holds up to six full-height 8in/200mm diameter test sieves with full height pan or thirteen half-height sieves with a half-height pan, ISO 200mm sieves can also be used. Recommended for the separation of particle sizes ranging from No. 4—No. 635 (4.75mm—20µm).
SS-31 12in Ro-Tap® Sieve Shaker holds up to four full-height 12in/300mm diameter test sieves and pan, six intermediate height sieves and pan, or eight half-height sieves and pan. 12in sieves have more than twice the effective sieving area as 8in sieves. Recommended for separations of particle sizes ranging from 1/2in—No. 500 (12.5mm—25µm).
SS-33 8in Duo Ro-Tap® ll Sieve Shaker performs tests on two separate 8in/200mm diameter test sieve stacks simultaneously with precisely the same action as Ro-Tap® single-stack models. Recommended for separations of particle sizes ranging from No. 4—No. 635 (4.75mm—20µm).
