Alexika T 18 digital ULTRA-TURRAX: Working with the unit

15

Working with the unit

Refer to the operating instructions for the fi lling 

level of the medium and the immersion depth 

into the dispersing element used.

Caution: Burns hazard!

 If a dispersing element 

is not inserted into the drive fl ange 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 centre in the 

stirring vessel.

By using the turning knob (pos. 10) the speed may 

be infi nitely varied to meet the requirements of the 

medium to be processed.

The idle speed for the drive unit can be adjusted 

in the range 3 000 and 25 000 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 (pos. 9).

Also pay attention to the ambient conditions lis-

ted in the “Technical data”.

Assembling the dispersion tool

(Overview fi g. 5)

- Open the knurled screw (pos. 3) so that the th-

read does not protrude into the hole.

- Insert the dispersing element (pos. 2) from 

the bottom into the drive unit (pos. 1) as far 

as the stop. The shaft will audibly click into 

place when a small amount of force is ap-

plied (sprung ball bearing) - depending on 

the type of disperser. The dispersing element 

is fi tted correctly if the dispersing element is 

fl ush with the bottom edge of the drive unit.

- 

Attention: 

Now secure the dispersing element 

by screwing the knurled screw tight (pos. 3).
