ATM L3P SONIC SIFTER (PHYSICAL PARTICLE SEPARATIONS)
The original Model L3P Sonic Sifter Separator operates by using sonic pulses combined with mechanical agitation, to provide effective separation of particles in size ranges otherwise unattainable. If you are trying to accomplish non destructive separation of small particles and /or small samples, the L3P is a requirement. Vacuum sievers aren't designed for fines retention, and standard sieve shakers aren't designed for separations below ASTM E 11 Wire Mesh Aperture Sizes.
NOTE: For non destructive separation of fines below 20 microns, for precision applications, the Horizontal Pulse Accessory is required.
Using specially designed 3.5 inch (75mm) diameter precision micro-plate sieves, and a patented oscillating air column, the L3P achieves dry, fine particle separations down to 3 microns, with a tolerance of +/- 2 microns. (ASTM E 161) Tighter tolerances are attainable with ultra series electro-formed sieves or custom geometry apertures.
The oscillating air column causes no screen wear or particle attrition, and facilitates endpoint separations in 90% less time, than with standard shaking methods.Practical separation of particles can be accomplished quickly - in less that 10 seconds under favorable conditions,
(Materials with high moisture content, or that agglomerate easily, may not be suitable for use with a sonic sifter. Call if you are unsure.)
Because the sieves are only three inches in diameter, a 10 gram maximum sample size
is recommended. (For very small particle separations, 2 grams or a maximum 4cc by volume sample is recommended) Larger particles should also be separated out first.
Not recommended for cohesive powders.

The unit is virtually maintenance-free, with no need for periodic adjustments or recalibration. Each L3P Sonic Sifter Separator is shipped with a one-year limited warranty, covering parts and workmanship. Prior to shipping, each unit is run for a minimum of four hours to assure optimum performance upon delivery. The Model L3P Sonic Sifter Separator is listed by Underwriters Laboratories, Inc.®
The ATM Model L3P Sonic Sifter Separator is calibrated at the factory to obtain reproducible test results at the "required" power level...a powerful analytical testing tool. Both the power input and the operating time interval can be adjusted for different sieving conditions.
Sieve stack assembly holds up to (5) sieves or combination of spacers and sieves
