Four steps to effective pigment dispersions starting from
· Pigments with a harder texture can be more finely dispersed by using a media mill which produces significantly more shear such as horizontal vertical and basket mills. In order to disperse the pigment to a nano level the use of 0.30.5 nm grinding media is recommended. Stabilization

Comminution of Pillsfritsch.de
Due to impact blow and friction effects of the grinding balls the sample is comminuted effectively. The maximal possible rotational speed for planetary mills is limited to approximately 800 rpm. The decisive difference of the premium line to a conventional mill is the tensioning of the grinding bowls.

Cell Disruption Getting the RNA Out Thermo Fisher
The supernatant is centrifuged again at a higher speed to pellet the bacterial cells (5). From this point cells can be lysed as described above for bacteria. Other techniques describe RNA isolation from the soil or sediment directly. For example one method requires soil to be added to a bead mill along with diatomaceous earth and lysis buffer.

Effect of grinding media properties and stirrer tip speed
· This was ascribed to the stress energy and stress number of the grinding media which were positively correlated with the stirrer tip speed when other grinding conditions were maintained constant (according to Eqs. ). This indicated that the particles of the material received more frequent and higher energy per collision between the approaching grinding media causing the breakage rate of class 1
