Placement of cleaning items
Caution!
The ultrasonic bath has been designed for the
ultrasonic treatment of items and liquids only.
Do not clean living beings or plants!
Do not reach inside the tank during ultrasonic operation!
Cell walls can be damaged by prolonged exposure to ultrasonic
activity.
For placing and taking out the cleaning items always switch off
the unit.
Do not place the cleaning items directly onto the bottom of the
cleaning tank, as this might lead to damages to the unit.
Place the cleaning items into the stainless steel cleaning basket
(accessory equipment).
For the use of cleaning chemicals which might destroy or
damage the stainless steel tank use a separate container. For
the special plastic cleaner tank for acid chemicals please
contact your supplier.
For certain applications it may be required to keep the
temperature of the cleaning liquid below a predefined maximum
temperature. As the liquid in the tank is heated by the ultrasonic
activity, it may be necessary to cool the liquid by means of an
external laboratory cooling device (cryostat). The manufacturer
of the present ultrasonic unit offers a special cooling coil which
can be clipped onto the tank wall and connected to a cryostat.
Caution!
When you operate the ultrasonic unit with cooled
cleaning liquid ensure that the temperature of the cleaning
liquid remains above room temperature. Otherwise there is a
risk of condensation which may cause damage to the
electronics.

After the cleaning
When the cleaning process is finished rinse the cleaning items,
e.g. under the tap.
Drain the liquid as soon as it is dirty or when the unit is not
operated over a prolonged period of time. Certain residues and
types of contamination may destroy or damage the stainless
steel tank.
Use the quick-drain duct to drain the cleaning tank
(
see section 4.6
).
