Their rotor\/stator system ensures optimal size reduction of the solids and at the same time increases the surface area of the powder in the liquid. This produces agglomerate-free solutions within a few minutes.<\/p><p>Breaking up the <a href=\"\/active-substance-deagglomeration\/?lang=en\">agglomerates<\/a> makes the entire particle surface accessible to the liquid. As a result, active substances dissolve faster and more evenly, <a href=\"\/suspensions\/?lang=en\">suspensions<\/a> become more homogeneous and dosing accuracy increases.<\/p><p class=\"svt-knote\">For poorly soluble active substances, a finer particle size can improve the dissolution rate and thus bioavailability. True micronisation down to a few micrometres, however, usually requires jet mills, bead mills or high-pressure homogenisers.
