• The dispersion tool is not suitable for continuous operation. Likewise the
optimal dispersion duration and rotating frequency must be determined
by attempts. Usually a few seconds are sufficient, maximum duration is
one minute. Longer application times bring no improvements, increase
however the sample temperature substantially.
• Dispersing causes the medium to heat up.
• Note the min./max. immersion depth in the "Technical data".
• The function of the dispersion tools depends on the condition of the sharp
edges of rotor and stator (integrated in the shaft tube). Abrasive media can
round off these edges fast, whereby the disperse effect diminishes.
• The gasket and bearings are made of PTFE and rustproof steel; the fol-
lowing points should therefore be noted: Chemical reactions of PTFE
occur in contact with molten or solute alkali metals and alkaline earth
metals, as well as with fine powders of metals in groups 2 and 3 of the
periodic system at temperatures above 300 °C - 400 °C. Only elemen-
tary fluorine, chlorotrifluoride and alkali metals attack it; halogenated
hydrocarbons have a reversible swelling effect.
