Innovation of conventional measurement method!
Water or other liquid is sprayed to powder or slurry on the sieve for wet sieving.


Fig. 1 Principle

Water is sprayed through the rotating sprinkler nozzle to disperse the sample. The Viblette is supplied with a vibration mechanism to assist in the dispersing of the sample agglomerates and the breaking of potential liquid membranes on the sieve in order to achieve stable sieving.


Fig. 2 Example of Sieving Performance

Current Wet Sieving

  • Excessive time needed
  • Messy process
  • Splashing Liquid
  • Inaccurate measurement values
  • Process skill required


Advantages of the Viblette

  • Reliable measurement values
  • Reduced analysis time
  • Repeatable measurement protocol

Achieve accurate measurement results within a short time.

For Nonoparticle - Barium titanate -

Ultrasonic type

For wet sieving of strong cohesive powders, Ultrasonic + mechanical vibration model (VBL-FU) is suitable instrument.

Sieving silica particles with the Viblette

Below sieving silica particles are using a 5μm screen with the Viblette VBL-F-Ultra.
