The drive unit opens up a wide range of possibilities for dispersi-
on technology in the conventional laboratory with a respective per-
formance output of approximately 300 watts at 24,000 1/min.
The speed of the
ULTRA-TURRAX
®
T 18 basic
dispersion unit is
set by using the differently adjusting wheel. In order to measure
the speed of the dispersion unit an
IKA
DZM control tachometer
may be connected after removal of the cover (pos. 3) (see fig. 1).
The delivered extension arm is mounted as follows (overview fig. 1):
• Insert extension arm (pos. 1) into flange
• Screw in the cylinder head screw (pos. 2)
• Firmly tighten cylinder head screw (pos. 2) using the A/f 4 right
angled screwdriver.
Vibrations may loosen the cylinder head screw. Therefore, for your
own safety, periodically check that the extension arm is secure. If
necessary, retighten the cylinder head screw.
To ensure safe operation the driving unit is fastened to the plate
stand R 1826 (pos. 8) by means of a cross sleeve (pos. 7).
In order to enhance the stability of the mechanical arrangement, the
driving unit has to be mounted as close as possible to the stand pillar.
Check that the voltage listed on the designation plate matches the
mains voltage. Also pay attention to the ambient conditions listed
in the “Technical data”.The power socket used must be earthed
(protective earth conductor contact).
Assembling the dispersion tool (overview fig. 1)
- Open the knurled screw (pos. 10) so that the thread does not
protrude into the hole.
- Insert the dispersing element (pos. 9) into the drive unit from
below until the recessed edge is flush with the bottom edge of
the drive unit. Turn the dispersing element to ensure that it rea-
ches the end stop (audibly clicks into place).
- Now secure the dispersing element by screwing the knurled
screw tight (pos. 10).
The distance between the dispersion tool and the vessel bottom
should not be less than 10 mm.
The filling level of the medium may not be less than about 55 mm.
Please observe also the operating instructions of the dispersion
tool to ensure a safe usage.
The entire unit may also be arranged somewhat off centre in order
to avoid any undesired air admission caused by the strong rotatio-
nal turbulence.
The adjustment wheel (pos. 4) is set at the lowest speed before
the unit is switched on. The speed which is set may be read by
comparing the colors on the scale (pos. 4) and the adjustment
wheel.
By using the adjustment wheel (pos. 4) the speed may be infini-
tely varied to meet the requirements of the medium to be pro-
cessed. The no-load speed of the
ULTRA-TURRAX
®
T 18 basic
driving unit may be set between 3,500 and 24,000 1/min.
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 (pos. 6).
