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.

Advantages of the Viblette
Achieve accurate measurement results within a short time.
Fig. 3 Ultra sonic type, VBL-FU
For wet sieving of strong cohesive powders, Ultrasonic + mechanical vibration model (VBL-FU) is suitable instrument.
Below sieving silica particles are using a 5μm screen with the Viblette VBL-F-Ultra.
