VariSifter

SONIC SEPARATOR

Download VS1000 Tear Sheet

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.

L3P

SONIC SIFTER

Download L3P Tear Sheet

Tried and true for 50 years, the world’s ORIGINAL Sonic Sifter Separator, otherwise known as the L3P, has become the industry standard and the go-to technology for precision research and quality assurance applications.

Producing results that are typically only achieved by wet sieving, this device uses specially designed 3” diameter clear sieves and an oscillating air column, created by a sonic wave, to separate fine particles. This technology dramatically shortens test times, is virtually maintenance-free and produces consistent, accurate results.

Individual parts or a complete set can be purchased.

IMPORTANT: Diaphragms and Fines Collectors are made from Latex and replacements are most often needed by customers. They have a limited shelf life from the date of manufacture. 

• Column Lock* – This metal (aluminum and stainless steel) fixture’s arms locks on to the Base/Fines Collector Holder, holding the Stack Assembly together for it to be placed into the sifter’s Test Chamber. Once inside the Test Chamber, the locking arms are released and tension holds the Stack Assembly in place during testing. The arms are then reengaged with the Base/Fines Collector Holder so the Stack Assembly can be removed from the sifter safely after testing.
• Diaphragm – This latex disk encloses/covers the particles within the top cone so they do not escape. During testing, the column of air caused by the sonic wave’s effect on the membrane assists in the trying of particles. Diaphragms inevitably wear out over time and have expiration dates.
• Top Cone – Clear acrylic funnel-like ring provides a loading area for of the test sample. It also assists in directing the sonic waves down the Column to best try the particles.
• Acrylic Spacer (6 for full Stack) – This ƒ?" high clear acrylic ring are used as extenders when either the test material needs more space to move or to complete the Stack when there are not enough sieves being used (full stack required for the Column to lock).
• Fines Collector – This latex pouch hangs at the bottom of the Stack and collects the finest particles. Fines Collectors inevitably wear out over time and have expiration dates.
• Base/Fines Collector Holder – This sturdy aluminum base holds the Fines Collector and is an anchor in which the Column Lock connects to during transfer.
