Proper Use; Unpacking; Useful Information - IKA ULTRA-TURRAX T 18 basic Operating Instructions Manual

Proper use

The ULTRA-TURRAX ® T 18 basic are dispersion units which, in
connection with a dispersion tool, manufacture emulsions and
dispersions. It is conceived for the employment in laboratories.
The disperser is conceived for the enterprise at a stand. Make
sure that the attachment mechanism is set up nontilting on a stur-
dy and even underbody and that the attachment mechanism
during the agitating procedure not to move begins.
The protection for the user is not ensured no more, if the equip-
ment with accessories is operated, which are supplied or are not
recommended not by the manufacturer or if the equipment in not
correct use is operated against the manufacturer default.

Unpacking

Please unpack the device carefully and inspect them for any dama-
ge. It is important that any damage is detected as soon as the
items are unpacked. A record of the relevant facts may be requi-
red (railway, mail or carrier).
The device delivery quantity includes: a driving unit, an extension
arm, a hexagon socket screw, a tool set and an operating manual.

Useful information

You have acquired a high-quality product. Used in combination
with an S 18- series dispersion tool, the drive unit is a high-speed
dispersing and emulsifying unit capable of handling free-flowing
and liquid media in batches.
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.
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 sufficient 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.
