1 Product description
Ultrasonic and rinsing bath, type SONOREX TECHNIK RM ... .
The exact type specification and serial number are found on the type plate, on the rear
side of the ultrasonic bath.
Product features:
• Stainless steel oscillating tank (1) with transducers, ultrasound frequency 40 kHz
• Easy-to-clean stainless steel housing (2)
• Filling level mark for safe filling (3)
• Weir/overflow (4) with ball valve to produce a liquid circuit.
• Legs (5) for a secure position
• Outlet with 3-way ball valve (6) for easy draining/filling of the bath fluid
• Depending on the model, with time switch (type "U") for 1 - 15 min or continuous
operation (7) and/or with heating (type "H") (8).

1.1 Mode of operation
SONOREX ultrasonic baths use the effect of cavitation. Under their oscillating tank
bottoms they contain piezoelectric transducers, the energy of which is transferred
to the bath liquid with ultrasound frequency as mechanical oscillations. As a result,
microscopically small bubbles are continuously formed in the bath liquid, which release
energy upon imploding and generate local microcurrents. This process is called
cavitation. During the cleaning process, it causes contamination to be "blasted" from
the hard surfaces of the objects being treated. At the same time, dirt particles are
removed and fresh bath liquid flows in.
During sonochemical processes, cavitation may have a catalytic effect, e.g. with the
production of stable emulsions or the rapid degasification of fluids with a high gas
content.
1.2 Purpose
SONOREX TECHNIK ultrasonic baths are intended for the sonication of aqueous
liquids. They work on the basis of low-frequency ultrasound and can be used in
versatile ways. Their main application is the gentle and intensive cleaning of objects of
diverse shapes, types and sizes.
Sonication is conducted using water and a preparation suitable for use with ultrasound.
In order to use the device as intended, an ultrasound-permeable basket or an appliance
suitable for positioning the objects during sonication is also required.
The unit is operated from the front. The SONOREX TECHNIK ultrasonic bath is usually
operated with the unit placed on a table.
1.3 CE conformity
The units satisfy the CE marking criteria in the European Union:
- Low-Voltage Directive
- Electromagnetic Compatibility Directive
- RoHS Directive
in their currently valid versions.
A declaration of conformity can be requested from the manufacturer by providing the
serial number.

Protected against access
to hazardous parts with
tools; protected against solid
objects with a diameter
of 2.5 mm or larger
Protected from dripping
water up to 15° from its
