Pulverisette 0 is an electromagnetic-powered mortar that transmits vertical oscillations to a single grinding ball, which in turn transfers the energy to the material being milled. Grinding forces can be controlled to enable very reproducible results. Samples of <5 mm material up to 10mL are ground, wet or dry, to analytical fineness. The unit produces a very narrow particle size distribution range. A Perspex viewing window permits observation. It comes with a built-in timer. Ship wt: 60 lbs. Select from three grinding materials to control abrasion and contamination. A transparent plexiglass hood for sound absorption is optional. The Pulverisette 0 power base can be converted to a wet or dry sieve shaker accommodating 8″, 200mm or 125 mm sieves. This is the same drive as used on the Analysette III.
