Gilson Rotary Sifter (115V/60Hz) offers an improved, reengineered version of a classic design for accurate sieving separations. Design advances, upgraded materials and quieter, more efficient operation make this unit an innovative standout in the industry.   Sieve stack capacity ranges from six 12in diameter full-height sieves with pan, or up to twenty 8in diameter half-height sieves with pan. Assembled sieve stacks are simply placed inside and the cabinet is rotated back against the stops with no clamping required. An ergonomic side knob allows easy rotation of the cabinet between the loading and testing positions. Six rubber-covered stainless steel drive rollers continuoulsy rotate the sieve stack, and particle separations are assisted by tapping against the stack. Recommended particle size range is No.4 to No.635 (4.75mm to 20µm).
