VarSifter Sonic Sifter for Fine Particle Separation


The next-generation sonic sifter. The VariSifter is a top-of-the-line particle separator that generates the same repeatable and reproducible results as with the original L3P Sonic Separator but with upgraded features including adjustable frequency, multiple built-in tapping options, touch screen and a universal power converter.

The device uses 3” clear acrylic sieves that, with an oscillating air column created by a sonic wave accompanied by tapping actions, are capable of quickly achieving separations of particles ranging from 5.6 mm down to 3 μm. Whether this is the first time purchasing a sonic sifter or you have been using the technology for years, the VariSifter is the new standard in fine particle separation.

  • Ideal for fine particle separation - Sieves range from 3 μm to 5.6 mm
  • Two built-in Horizontal Tappers - 2 horizontal tapping mechanisms, may be turned on or off
  • Frequency Control - Adjustable from 15 Hz up to 60 Hz
  • Amplitude Control - Adjustable from 0 - 100% clear acrylic framed sieves allow for a visual reference to determine proper power level and finish point
  • Accurate results and quick test times - Key-in testing with fully customizable variables
  • Internal universal power converter - Device can be used in any standard power environment 100vac to 240vac/50Hz or 60Hz
  • Touch Control Panel - Intuitive and easy to read touch monitor with dynamic Machine Status Indicator and clear visibility of your variables
  • Vertical mechanical pulse shears agglomerates and reorients the particles in the air column
  • Each unit includes a complete Stack Assembly comprised of: 1 Column Lock, 1 Diaphragm, 1 Top Cone, 6 Spacers, 1 Fines Collector and 1 Fines Collector Holder
  • One-year limited warranty
