Safety instructions
General information:
• Read the operating instructions in full before starting up and follow the safety instructions.
• Keep the operating instructions in a place where they can
be accessed by everyone.
• Ensure that only trained staff work with the device.
• Follow the safety instructions, guidelines, occupational
health and safety and accident prevention regulations.
DANGER
Beware of the risk of:
- flammable materials
- glass breakage
- sharp edges on the dispersing tool.
CAUTION
processed. There is a risk from:
- splashing and evaporation of liquids
- body parts, hair, clothing and jewellery getting caught.
• The device must only be used in a technically perfect condition.
• Do not cover the ventilation slots on the drive in order to
ensure adequate cooling of the drive.
• The voltage stated on the type plate must correspond to
the power voltage.
• Abrasion of the dispersion equipment or the rotating accessories can get into the medium you are working on.
Please pay attention to the dangerous parts of the equipment in Fig. 2.
Wear your personal protective
equipment in accordance with the
hazard category of the media to be
• Before switching on the dispersing device make sure that
the dispersion tool shaft is immersed in the medium. Observe the operating instructions of the dispersion tools.
• The distance between the dispersion tool and the vessel
bottom should not be less than 10 mm.
• Use the dispersion tool always inside the dispersing vessel.
• Do not use the device without a dispersion tool.
Working with the device:
DANGER
With substances capable of forming an explosive mixture,
appropriate safety measures must be applied, e.g. working under a fume hood.
To avoid body injury and property damage, observe the
relevant safety and accident prevention measures when
processing hazardous materials.
Only process media that will not react dangerously to the
extra energy produced through processing. This also applies to any extra energy produced in other ways, e.g.
through light irradiation.
The device is not suitable for hand-held operation.
Switch off the device at the power switch (item 8) or pull
out the mains plug when changing or handling the dispersing tool.
WARNING
Do not use the device in explosive
atmospheres, it is not EX-protected.
Do not touch rotating parts during
operation!
Device setup:
DANGER
If access to the power switch cannot be ensured, an additional emergency stop switch that can be easily accessed
must be installed in the work area.
WARNING
NOTICE
• Ensure that the dispersion tool is securely properly into
the drive unit.
• All screw connections must be properly tightened.
• Check that the turning knobs are secure and tighten if
necessary.
• Glass vessels must always be secured with a clamp to prevent them spinning.
The power switch of the IKA device
must be accessed immediately, directly and without risk at any time.
Make sure that the unit is stably
mounted. The vessel used for dispersing must be secured.
Set up the stand in a spacious area
on an even, stable, clean, non-slip,
dry and fireproof surface.
WARNING
If a dispersion tool is not inserted into the drive flange as
far as the mark it can become extremely hot in operation
and thus suffer damage.
CAUTION
speed and increase it gradually.
Reduce the speed if the medium splashes out of the vessel
because the speed is too high.
If the interaction between the medium and dispersing
element or working with dispersing tools with a stator
diameter ≥18 mm and a speed of more than 20000 rpm,
makes a loud noise, be sure to wear your personal protective equipment.
The dispersing tool and the coupling flange can become hot during
the operation.
Be aware that the unit starts with the
set speed, which is shown on the display. If uncertain start with the lowest

NOTICE
eration. This will prevent the infiltration of foreign objects,
liquids and other contaminants.
Never run dispersion tools dry, as the gasket and bearings will be destroyed if the tools are not cooled by the
medium.
• In the event of unbalance or unusual noises, switch off
the device immediately. Replace the dispersion tool. If
there is no difference after the change of the dispersion
tool, return it to the dealer or the manufacturer along
with a description of the fault.
• Ensure that the stand does not start to move.
• Meter powder cannot be placed too close to the flange.
Powder can be blown away by air turbulences of the drive.
• There may be electrostatic discharges between the medium and the dispersing device shaft which could pose a
direct danger.
Covers or parts that can be removed
from the device without tools must
later be refitted to ensure safe op-
Power supply / Switching off the device:
• The device can only be disconnected from the power supply by pulling out the power plug or the connector plug.
• Always disconnect the plug before fitting accessories or
cleaning.
• The socket for the power cord must be easily accessible.
• The device does not start up again automatically following a cut in the power supply.
• The device must only be opened by trained specialists,
even during repair. The device must be unplugged from
the power supply before opening. Live parts inside the
device may still be live for some time after unplugging
from the power supply.
Accessories:
• Protect the device and accessories from bumps and impacts.
• Check the device and accessories beforehand for damage
each time you use them. Do not use damaged components.
• Only dispersion tool approved by IKA may be used.
• Safe operation is only guaranteed with the accessories described in the ”Accessories” chapter.
Disposal of the device:
• The device must be disposed of in accordance with national
regulations

Useful information
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 dispersion 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.
Delivery scope:
- IKA T 25 easy clean digital or IKA T 25 easy clean control
- Extension arm
- Hexagon socket screw
- Screwdriver DIN 911
- USB 2.0 cabel (A – micro B)
- User guide
- Warranty card.
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 circumferential velocity of the rotor/stator arrangement is
6–24 m/s.
A processing time of a few minutes is usually sucient to
produce the desired fineness. Long processing times bring
only insignificant improvements in the obtainable fineness;
the energy expended serves merely to increase the temperature of the medium.

The drive unit opens up a wide range of possibilities for dispersion technology in the conventional laboratory with a
respective performance output of approximately 400 watts
at 25000 rpm.
Drive
The speed is set by using the operating knob. The motor
speed can be read from the LED display. For example, a value of 13.6 corresponds to 13600 rpm.
