Endecotts Sonic Sifter

For fast accurate separation down to 5 micron

The Sonic Sifter is a precision instrument for the rapid separation of a wide variety of dry particles and powders in the fine micron range.

It will successfully separate samples down to 5 microns in as little as one minute, sometimes less, with consistant repeatability.

The sieving action, which can be varied for different densities and textures of material , is unique. A verticle column of air is made to oscillate through a sieve or set of sieves. The motion of the air alternately lifts the sample and then assists it through the sieve apertures. The oscillation amplitude is variable. A vertical mechanical pulse may also be applied to the sieves at regular intervals to break down any clustered particles and help eliminate any binding of the apertures.

An important feature of the Sonic Sifter is that it causes very little attrition of the sample and virtually no screen wear.

  Outstanding value
  Simple to operate
  Unique action
  Very quick cycle time - typically less than one minute
  Virtually no attrition of sample
  Virtually no screen wear
  Very quiet operation

The sonic sifter can take up to 5.60 mm aperture sieves
