- Humboldt - Ro-Tap® II
Ro-Tap® Sieve Shakers have 278 oscillations and 150 taps per minute as specified in some ASTM and other sieving applications.
Horizontal, circular action combined with vertical tapping assures accurate and consistent results.
These shakers are designed for heavy-duty use and bolt easily to a solid table or sturdy bench top.
All models feature an adjustable-plate sieve support and built-in 99 minute x 0.1 second digital timer.
Powerful 1/4hp motors provide plenty of action for efficient separations.
For models operating on 230V/60Hz power, add "S" to the model number.
Sieves are ordered separately and a sieve cover is required.
Ro-Tap® II Sieve Shaker performs two 8in (203mm) sieve tests simultaneously with exactly the same action as the single-stack models.
Dimensions: 31x27x26in (787x686x660mm), WxDxH.
