4 Use of cleaning agents Elma Schmidbauer GmbH
8 / 32 Elmasonic Select
Cleaning agents
Volatile, corrosive or aggressive cleaning agents can cause chemical burns to the skin and respiratory
tract.
• Observe the safety data sheet when using cleaning agents.
• Wear the protective equipment stipulated in the safety data sheet.
• Where necessary, provide adequate extraction for the emitted vapours and regularly check that the
extraction system is working correctly.
• Observe the information stipulated in the Cleaning agents chapter. In case of doubt, ask the
manufacturer or supplier.
Ultrasound-conductive liquids and materials
Ultrasound damages the cell membranes and bone structure.
• Do not reach into the ultrasonic bath during ultrasound operation.
• During ultrasound operation, do not touch any parts that conduct ultrasound, such as the tank,
basket or any accessories used.
Ultrasound noise emissions
Working with ultrasonic cleaning units for longer periods of time can damage your hearing.
• Use the lid or wear personal ear protection when working on ultrasonic units.
• Pregnant women must not be subjected to the noise emissions for longer periods of time.
• Keep animals away from the vicinity of ultrasonic devices.
Electromagnetic radiation
• No binding statement can be made for persons with active medical implants, such as pacemakers or
implanted defibrillators. A binding statement can only be made for specific workstations and in
consultation with the implant manufacturer.
4 Use of cleaning agents
A cleaning agent can be added to the liquid in the tank to improve the cleaning results.
If using cleaning agents, observe and apply the instructions stated in the safety data sheet and product
information.
Also observe the following information:
4.1 Permissible cleaning agents
• Only use aqueous cleaning agents for ultrasonic cleaning.
• Only use cleaning agents that are suitable for ultrasonic cleaning.
Elma provides a wide range of aqueous cleaning agents developed in-house that are optimised for
ultrasonic cleaning.
A list of Elma cleaning agents can be found here:
https://www.elma-ultrasonic.com/en/products/cleaning-chemistry/
4.2 Cleaning agents
The following limitations also apply if the chemical compounds listed below are introduced as
contamination or in the form of carry-over into the stainless-steel tank filled with cleaning agents.

Elma Schmidbauer GmbH 4 Use of cleaning agents
Elmasonic Select 9 / 32
Use of aggressive, corrosive cleaning agents:
Aggressive, corrosive cleaning agents can cause severe chemical burns if they come into contact with
eyes or skin. Insufficient ventilation can result in severe chemical burns to the respiratory tract.
• Before using any cleaning agents, read the safety data sheet and product information and observe
and apply the instructions.
• Where necessary, install an effective extractor system for the emitted vapours (e.g. at higher
temperatures) and regularly check that the extractor system is working correctly.
• Never reach into the tank when filled with cleaning agent.
• Wear suitable protective equipment in line with the safety data sheet.
Danger of fire or explosion when using combustible cleaning agents
Ultrasound and heat increase the evaporation of liquids and form extremely fine mists that readily
ignite on contact with sources of ignition. This can result in severe burns or death.
• Do not use cleaning agents that are labelled with the pictograms GHS01 (explosive), GHS02
(flammable) or GHS03 (oxidising) in line with the CLP regulation (EC no. 1272/2008). Do not use
cleaning agents that have a flashpoint.
• If necessary, clarify the cleaning agents that can be used by consulting the manufacturer or
supplier.
GHS01 GHS02 GHS03
Table2: GHS pictograms for explosive, flammable or oxidising substances
Damage to the stainless-steel tank caused by unsuitable cleaning agents
Unsuitable cleaning agents can cause pitting and therefore damage the stainless-steel tank within a
short time.
• Consult the unit and cleaning agent manufacturers to clarify whether the cleaning agent is
suitable.
• Do not use any cleaning agents in the acidic pH range (pH value <7) at the same time as halides,
such as fluoride, chloride, bromide or iodide.
• Only use cleaning agents that are suitable for ultrasound applications.

üThe unit and the tank are clean and, if necessary, disinfected.
üThe filled basket or insert is hooked into the tank.
IMPORTANT When filling the tank without a basket or insert in place, please note that inserting the
basket or insert will cause the filling level in the tank to rise. To prevent the tank from overflowing,
do not fill the tank up to the fill level marking. If necessary, top up the tank after inserting the
objects.
1. Add the cleaning fluid to the tank up to the fill level marking using, for example, a measuring jug.
The fill level marking is the stacking collar (1) in unit sizes
Elmasonic Select 30–300 and the embossed mark (2) in unit sizes Elmasonic Select 500/900.
CAUTION!An overfilled tank can cause the cleaning fluid to boil over at high
temperatures.
