Ultrasonic cleaning process
7.3 Degas mode (degassing of HPLC solvents)
The USC 200 S can be operated in a special degas mode.
The degas mode provides an efficient degassing of the filled
liquid within approx. 30 minutes. The gas contained in the liquid
is „collected“ to form macroscopically large bubbles and then
taken out of the liquid in short ultrasonic breaks. The degas
mode is also good for the degassing of samples, e.g. for the
degassing of carbon dioxide in the food sector.
Turn the turning knob ( Illustration 4.7.B .) to the right (clockwise)
to switch the unit on.
Set the required operation time (short period operation or
continued operation) as described in
section 4.7 .
Press the key
►
■
to start the ultrasonic operation.
Press the key degas to activate the degas operating mode.
Sieve cleaning, degas and sample preparation modes cannot
be operated simultaneously.
7.4 Sample preparation mode
The USC 200 S can be operated in a special sample
preparation mode.
In this mode the unit operates in a stronger ultrasonic mode
(Pulse).
The sample preparation mode is ideal for standard laboratory
applications, such as mixing, dissolving, dispersing, cleaning,
etc.
Turn the turning knob ( Illustration 4.7.B .) to the right (clockwise)
to switch the unit on.
Set the required operation time (short period operation or
continued operation) as described in
section 4.7 .
