Sonic Sifter Separator
A superior sieving instrument, the Sonic Sifter Separator is precise, versatile and ideal for research and quality assurance applications. It’s especially effective with “difficult” dry powder materials previously considered too fine for particle analysis

Specially designed 3" (75mm) diameter acrylic-framed sieves and a patented oscillating air column allows this unit to achieve efficiencies previously seen only with wet sieving for materials in powdered, granular or pellet form— and is capable of achieving separations over the range of 3µm to 5.6mm.

With the Sonic Sifter:

  • Particle separations can be accomplished in less than 10 seconds under favorable conditions. And testing times can be cut by up to 90%, compared to other methods.
  • Action can be varied for different densities and textures.
  • Automatic timing ensures repeatable results.
  • Separated fractions of material are retrievable.
  • All sieves can be conveniently direct-tared on conventional analytical balances.
  • Special see-through acrylic-framed sieves help determine proper power level and finish point.
  • Power level to separate particles is infinitely adjustable.
  • A vertical, oscillating column of air "tries" the particles 60 times per second, and a vertical mechanical pulse shears agglomerates and reorients the particles in the air column.
  • No horizontal scrubbing of the particles occurs as in standard sieve shakers.
  • Operation requires a very short learning curve.
  • There's no need for periodic adjustments or recalibration.
  • Unit holds up to six standard sieves or three precision mesh, double height sieves.
