4.2 General use
Step 1: Fill oscillating tank
The oscillating tank is fi lled with water and a suitable preparation to reduce the surface tension,
see chapter 7.2.
Direct sonication
 Fill 1/3 of oscillating tank with water.
 Add dosed preparation to the oscillating tank.
See appendix for dosage information.
 Fill carefully up to the fi lling level mark, avoid as much as possible the formation of foam.
Indirect sonication
When using aggressive acidic liquids (e.g., sulfuric acid, hydrochloric acid), we recommend using
alkaline contact liquid such as 5% TICKOPUR R 33.
 Fill 1/3 of oscillating tank with water.
 Surfactant.

Fill carefully, avoid as much as possible the
formation of foam.
The oscillating tank must be
fi lled contingent upon the inset beaker since inset beakers
displace the contact liquid.
Step 2: Degassing the fl uid
Freshly- fi lled bath fl uid or fl uid that has remained in the oscillating tank for a longer period of time
must be degassed prior to use. See also chapter 4.4.1.
 Remove basket and other accessories from the oscillating tank.
 Switch on ultrasonic bath.

Place lid on top.
 For degassing, set the time and start the ultrasound (Press START/STOP button for 2 sec),
see chapter 3.1.1 and 3.2.
-
up to 10 litres bath volume: 10 min
- more than 10 litres bath volume: 30 min
Time need to be extended with acidic cleaning solutions.
Step 3: Preheat fl uid
In ultrasonic baths with built-in heating, the fl uid may be preheated independently of the
ultrasound. This increases the ultrasound effect, especially when removing fats, oils and polishing
paste residue, and shortens the duration of the subsequent ultrasound.
 Remove basket and other accessories from the oscillating tank.
 Place lid on top.
 Set the desired temperature, see chapter 3.1.2. The ultrasonic bath begins to heat
immediately.
 For an even warming of fl uids, stir the fl uids or switch on the ultrasound for a few minutes now
and then, otherwise there will be a retardation of boiling - risk of scalding!
