Proper use

The ULTRA-TURRAX® T 50 basic is a dispersion unit suitable for manu-
facturing emulsions and dispersions in combination with a dispersion tool.
The drive unit must be operated on a stand.

Unpacking

The ULTRA-TURRAX® T 50 basic is supplied fully assembled. The
dispersion tools are also supplied fully assembled.
Unpack the unit and the dispersion tools carefully and check thoroughly
for damage. It is important that any damage is recognized on unpacking,
as an immediate damage report may have to be made (post, rail or
shipping firm). As supplied, the package contains: one ULTRA-
TURRAX® T 50 basic drive unit, one boom arm, one hexagon nut, one
set of tools and one set of operating instructions.

Useful information

You have acquired a high-quality product. Used in combination with an
S 50 series dispersion tool, the ULTRA-TURRAX® T 50 basic 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 continuum 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 10-24 m/s.
A proces-
sing time
of a few
minutes is
usually
sufficient
to produce
the desired
fineness.
Long
proc-
cessing
times bring only insignificant improvements in the obtainable
fineness; the energy expended serves merely to increase the
temperature of the medium.

Drive unit

With its power consumption. 1100 W at 10,000 rpm, the drive unit is
suitable for a wide range of everyday dispersion applications in the
laboratory.
The speed of the T 50 basic dispersion unit can be infinitely adjusted by
using the numbered adjustment wheel.
An IKA-DZM control revolution counter can be inserted into the bore hole
(10) in order to measure the speed. (cf. Fig. 1)
