For gentle cleaning of test sieves, micro-precision sieves and other sensitive parts without damaging them. Also for dispersing of suspensions for particle size analysis. Fill volume: 5.6 litres.

Areas of Application
  • For especially gentle and damage-free cleaning of even extremely sensitive parts such as glassware, sieves or valuable micro-precision sieves.
  • The LABORETTE 17 is also suitable for external dispersion of suspensions for particle size analysis, and for the acceleration and improvement of process sequence of chemical reactions such as the extraction of plant substances. Two further additional functions are the degassing of liquids and the emulsifying of oily and aqueous phases.
Method of Operation

The ceramic oscillator generates high-energy vibrations at the base of the bath, creating a cavitation effect throughout the bath liquid. The change in pressure caused by the cavitation dissolves stubborn soiling even at the most inaccessible points.
