5.8 Degassing the sonication fluid – DEGAS
Sonication fluid that has been freshly filled or left in the ultrasonic
oscillating tank for a long period must be degassed before use.
Degassing the sonication fluid increases the effect of the ultra-
sound. You can use the DEGAS function to perform rapid degassing
of the sonication fluid.
1. Press the start/stop button for at least 2 seconds.
» The ultrasound is switched on.
» The LEDs indicate the remaining degassing time.
2. To end degassing earlier, press the start/stop button.
Information
The ultrasound noise becomes quieter during degassing. This
means that the ultrasonic effect is increasing.
5.9 Adding goods to be treated
To achieve good results, observe the following information when
inserting goods to be treated:
• Each time before sonication, check whether the sonication fluid
is contaminated. If there is visible contamination, replace the
sonication fluid.
• The sonication fluid must be degassed. See chapter
sing the sonication fluid – DEGAS
.
• The sonication fluid must be preheated to the required working
temperature before you add objects.
• Use suitable accessories, e.g. a basket. Do not place any objects
directly on the bottom of the ultrasonic oscillating tank. Use a
studded silicone mat for sensitive objects. See chapter
.
• Insert objects so they are distributed. Do not stack them. Sensi-
tive objects may not touch other objects.
• The ultrasound must be switched off while objects are being
inserted.
• Check the filling level. The goods to be treated must be com-
pletely submerged in the fluid. Inset beakers for indirect sonica-
tion need to be submerged at least 2 cm in the sonication fluid.
• Remove air bubbles from cavities. Rotate the objects accord-
ingly. Remove air bubbles under inset beakers. The ultrasound
