features / benefits

• Additional Sonic Sifter Features and Benefits.
• • Sieving action can be varied for different densities and textures of materials.
• • Sieving can be timed automatically to ensure repeatable results.
• • Separated fractions of material (even below 5 micrometers) are retrievable for further evaluation after the analysis is complete.
• • All sieves can be conveniently direct-tared on conventional analytical balances, eliminating the need to transfer retained samples for mass determination.
• • Special see-through acrylic-framed sieves allow operator to determine proper power level and finish point for testing.
• • Power level to separate particles is infinitely adjustable by operator as test progresses.
• • A vertical, oscillating column of air 'tries' the particles 60 times per second on the screening surface, and a vertical mechanical pulse shears agglomerates (as in many conventional sieve shakers). The sifter then reorients the particles in the air column.
• • No horizontal 'scrubbing' of the particles occurs as on standard sieve shakers. This scrubbing is the largest single cause of particle breakdown or attrition.
• • Operation requires a very short learning curve.
• • The unit is virtually maintenance-free, with no need for periodic adjustments or recalibration.
• • The unit has a capacity of up to six standard sieves or three precision mesh, double height sieves.

• A Powerful Tool: The Original 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-frame 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.

• • A unique oscillating air column moves even the finest particles through a stack of screens.
• • The Sonic Sifter is virtually maintenance free.
• • Quiet operation makes this unit suitable for most laboratory installations.
• • There’s no screen wear or particle attrition.
• • Digital timer for precise operation.
• • Capacity of six standard or three precision sieves per test run.
• 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.

The Model L3-N8 Horizontal Pulse Accessory

• A must for accurate separations below 45μm, this electromechanical device eliminates agglomerates in extremely fine powders. A tapping action alternates on opposite sides of the screen frame to create a high speed shock wave, breaking down agglomerated materials and reintroducing near-sized particles back into the air stream, and then back onto the screening media.
  (110 vac 50 or 60 HZ)

Includes: Power supply with electrical line cord for 110 volt operation, machined pulse assembly designed to fit in the sieve stack of the Sonic Sifter Separator.
