The durable UltraQuiet ™ Mary Ann® Laboratory Sifter continues to be the industry standard for accurately sifting aggregates into proper particle sizes. The new generation Mary Ann units are UltraQuiet™, with wheels for easy relocation and a SieveRack™ under the unit for easy storage of sieves. Inside a handmade enclosure 8” or 12” sieves can be stacked up to 26” in height and placed inside the Mary Ann without clamping. The Mary Ann features wood hammers that preserve the integrity of your sieves, helping you avoid sieve inspection failures. The inclined, rotating stack of sieves provides a gentle and thorough tumbling action, which allows the particles to pass through the mesh. The sifting process is repeated on the smaller meshed sieve—and so on down through the stack.
