Ultrasonic cleaning process

frequency and ultrasonic power if required for the intended
application.

 pressed (> 2 sec.):

The unit starts heating up.
During the heating-up process the ultrasound is regularly
activated to mix the liquid.
The display shows the set cleaning time (flashing).
When the set temperature is reached the ultrasound is
switched on for the duration of the set cleaning period.

When the set cleaning period has run down, the ultrasonic 
activity is automatically switched off. The heating continues 
operating at the set temperature. 

7.3 

Degas mode 

Special operating mode for the quick degassing of HPLC 
samples or solvents 

The oxygen bubbles contained in the liquids are carried into the 
atmosphere quickly and efficiently by means of a specialized 
modulation and clocking of the ultrasonic waves.

degas

. The LED in the 

degas

 

key indicates that the Degas mode is activated. 

The Degas mode can be switched on at any time during 
operation. 

Degas, Sweep and Pulse cannot be operated simultaneously. 

7.4 

Sweep mode 

During standard ultrasonic operation, zones of increased 
ultrasonic intensity form directly above the transducer systems, 
and zones of lower ultrasonic intensity can be found along the 
edge zone of the tank. This is a positive effect which can be 
used for the sounding of glass beakers, Erlenmeyer flasks etc. 
by positioning them directly into these zones. 

For large cleaning items, however, it may be useful to switch on 
the Sweep mode. 

A more homogeneous sounding of the cleaning bath is 
achieved by the continued displacement of the sound pressure 
maxima in the cleaning liquid. This leads to a more uniform 
ultrasonic intensity throughout the ultrasonic tank.
