Wear your personal protective
equipment in accordance with the
hazard category of the media to be
processed. Otherwise there is a risk from:
- splashing and evaporation of liquids
- body parts, hair, clothing and jewellery getting caught.
• Set up the stand in a spacious area on an even, stable,
clean, non-slip, dry and fireproof surface.
• Check the appliance and accessories beforehand for dam-
age each time you use them. Do not use damaged com-
ponents.
• The appliance is not suitable for manual operation.
• The agitation vessels used for dispersing have to be se-
cured. Consider on a good stability of the entire structure.
• Secure the agitation vessel against twisting.
• Check that the turning knobs are secure and tighten if
necessary.
• Glass vessels must always be secured with a clamp to
prevent them spinning. When working with flasks elastic
couplers must be used to prevent fracture of the glass.
• Note the operating instructions of the dispersing tool and

• Please observe the permitted speed for the dispersing ele-
ment. Never set higher speeds.
• Do not use the appliance without a dispersing element.
• Use the dispersing tool always inside the stirring vessel.
• Never run dispersion tools dry, as the gasket and bearings
will be destroyed if the tools are not cooled by the medium.
If a dispersing element is not insert-
ed into the drive flange as far as the
mark it can become extremely hot
in operation and thus suffer damage.
• Make certain that the unit is set at the lowest speed be-
fore commissioning; otherwise, the unit will begin run-
ning at the speed last set. Gradually increase the speed.
• Reduce the speed if the medium splashes out of the vessel
because the speed is too high.
• Before switching on the dispersing instrument make sure
that its shaft is immersed min. 45 mm in the medium to
prevent the medium from splashing out.
• The distance between the dispersion tool and the vessel bot-
tom should not be less than 10 mm.
• Ensure that the stand does not start to move.
• In the event of unbalance or unusual noises, switch off the
appliance immediately. Replace the dispersing element. If
there is no difference after the change of the dispersing
tool, return it to the dealer or the manufacturer along with
a description of the fault.
Do not touch rotating parts during op-
eration.
• When in operation, the dispersing element and the cou-
pling flange can become hot.

appropriate safety measures must be applied, e.g. work-
ing under a fume hood.
To avoid body injury and property damage, observe the rele-
vant safety and accident prevention measures when process-
ing hazardous materials.
Only process media that will not react dangerously to the
extra energy produced through processing. This also ap-
plies to any extra energy produced in other ways, e.g.
through light irradiation.
• There may be electrostatic discharges between the medi-
um and the dispersing instrument shaft which could pose
a direct danger.
• Only process media that will not react dangerously to the
extra energy produced through processing. This also ap-
plies to any extra energy produced in other ways, e.g.
through light irradiation.

Useful information
Unpacking
Dispersion is the dissolution and diffusion of a solid, liquid
or gaseous phase in a liquid that is not consolute with that
phase.
The rotor/stator principle:
Due to the high rotation speed of the rotor, the medium
to be processed is automatically drawn axially into the dis-
persion head and then forced radially through the slots in
the rotor/stator arrangement. The high accelerations acting
on the material produce extremely strong shear and thrust
forces. In addition, high turbulence occurs in the shear gap
between rotor and stator, which provides optimum mixing
of the suspension.
The dispersion effectiveness is heavily dependent on the
product of the shear gradient and the time the particles
spend in the shear zone. The optimum range for the circum-
ferential velocity of the rotor/stator arrangement is 6-24 m/s.

A processing time of a few minutes is usually sucient to
produce the desired fineness. Long processing times bring
only insignificant improvements in the obtainable fineness;
the energy expended serves merely to increase the tempera-
ture of the medium.
Use:
When used in combination with one of our recommended
dispersion tools, the drive unit is a high-speed dispersing
and emulsifying unit capable of handling free-flowing and
liquid media in batches.
Production of:

Caution: Burns hazard! If a dispersing element is not in-
serted into the drive flange as far as the mark it can become
extremely hot in operation and thus suffer damage.
So as to avoid unintentional ingress of air into the medium
due to excessively turbulent rotation, the whole unit can be
placed a little off center in the stirring vessel.
By using the turning knob ( item 10) the speed may be in-
finitely varied to meet the requirements of the medium to be
processed.
The idle speed for the drive unit can be adjusted in the
range 3000 – 25000 rpm; the value will be shown on the
LED display.
If these conditions are met the unit is
ready for service when the mains plug
has been plugged in.
The driving unit is switched on by means of the On/Off-
switch (item 9).
The speed is set by using the differently adjusting wheel.
The motor speed can be read off the LED display. For exam-
ple, a value of 13.6 corresponds to 13600 rpm.
The drive unit opens up a wide range of possibilities for dis-
persion technology in the conventional laboratory with a
respective performance output of approximately 500 watts
at 25000 rpm.
To ensure safe operation the driving unit is fastened to the
plate stand R 1826 ( item 5) by means of a cross sleeve ( item 3).
In order to enhance the stability of the mechanical arrange-
ment, the driving unit has to be mounted as close as possi-
ble to the stand pillar.
The delivered extension arm is mounted as follows (over-
view fig. 1):
• Insert extension arm (item 1) into flange
• Screw in the cheese head screw (item 2)
•
Firmly tighten cheese head screw ( item 2) using the DIN 911
A/f 4 screwdriver
Vibrations may cause the cylinder head screw (item 2) to
loosen. Therefore, for your own safety, periodically check
that the extension arm is secure. If necessary, re-tighten the
cylinder head screw (item 2).

Working with the unit
Also pay attention to the ambient conditions listed in the
“Technical data”.
Assembling the dispersion tool:
(Overview Fig. 5)
- Open the knurled screw (item 3) so that the thread does
not protrude into the hole.
- Insert the dispersing element (item 2) from the bottom into
the drive unit (item 1) as far as the stop. The shaft will audi-
bly click into place when a small amount of force is applied
(sprung ball bearing) - depending on the type of disperser.
The dispersing element is fitted correctly if the dispersing
element is flush with the bottom edge of the drive unit.
- Attention: Now secure the dispersing element by screw-
ing the knurled screw tight (item 3).
