SECTION 1
Introduction to Ultrasonic Cleaning
Ultrasonic: what is it?
Ultrasonic Cleaners employ the use of sound waves at very high (inaudible) frequencies
(approximately 39 kHz) to agitate a cleaning medium, which in turn results in the removal of debris
and contaminants from the object being processed.
The Ultrasonic Cleaner’s tank is made up of an ultrasonic generator and two or three piezoelectric
transducers (depending on the model) that are placed on the external bottom of a stainless steel tank
containing the cleaning solution. The electronic generator produces a continuous signal at the
frequency of 39 kHz and drives the piezoelectric transducers that transform the electrical signal into
a mechanical vibration. This vibrational energy is transmitted to the cleaning solution within the tank
at a frequency of 39,000 oscillations per second. These pressure and depression oscillations create an
enormous quantity of microbubbles inside the cleaning solution that, by imploding in rapid
succession, create immense impact energy between the cleaning solution and the surface to be
cleaned. This is called "cavitation" and enables an efficient and safe cleaning system with reduction
in time.
Sweep System Technology
The Little Sister Ultrasonic Cleaner contains a brand new generator which incorporates a special
ultrasonic oscillator called Sweep System Technology. With this technology, the output frequency
of the ultrasonic generator is modulated around a central frequency, so the transducers working at a
frequency of 39 kHz are modulated at a frequency between 38 and 40 kHz. This frequency modulation
offers the following advantages:
• Decreases cleaning times;
• Prevents the damage of delicate parts to be cleaned;
• Decreases the effects of stationary waves increasing the distribution of ultrasonic energy in
the cleaning solution;
• Improves cleaning results and facilitates the cavitation in liquids that are difficult to cavitate
with traditional ultrasonic systems.
SECTION 2

Instructions for Use
Little Sister UltraSONICA m Ultrasonic Cleaner / Rev.00 – Dated 09/12/2019
Recommended Cleaning Solution
The Little Sister Ultrasonic Cleaner should only be used with the cleaning solution recommended
by the manufacturer.
To clean any instrument, you should principally use clean running water and dissolve in it a quantity
of detergent or solution depending on the type of material residue to be removed from the instrument
itself. Use only solutions that are appropriate to the type of work to be performed. Only use undiluted
detergent if it is explicitly specified in the product's instructions for use. Use only the amount of liquid
needed to clean. Always follow the instructions for use of the solution.
Do not use any of the following solutions:
• Acidic or strong alkaline solutions such as sodium hypochlorite because these substances,
when in direct contact with the tank, cause a series of microscopic holes with irreparable and
especially dangerous consequences for the operation of your device.
• All acidic or alkaline substances that can release corrosive compounds such as chlorine or
other chemical compounds, or glutaryaldehyde disinfectants, used together with the energetic
ultrasonic cavitation activity, can cause accelerated corrosion of stainless steels.
• Substances such as petrol, benzene, benzol or other harmful, explosive or flammable solvents.
Any acid particles, micronised by intense ultrasonic cavitation activity, are dispersed in the working
environment causing corrosion to the device and also damaging health.
Preventing damage to the device
To prevent damage to the device:
• Periodically replace the solution. It is recommended that the cleaning solution is replaced at
the end of every session, or as a minimum daily, unless local guidance recommends a more
frequent schedule or if the solution is heavily contaminated.
• Do not operate the device without the recommended cleaning solution.
• Do not put parts or containers directly in contact with the bottom of the tank, use the stainless
steel basket provided.
• When the Ultrasonic Cleaner is in operation, make sure that the cleaning solution does not fall
below 2/3 of the total height of the tank.
Failure to follow such instructions may cause damage to the transducers, invalidating the warranty.

Useful tips and suggestions
The type of cleaning solution to use. To clean any instrument, you should principally use clean
running water and dissolve in it a quantity of detergent or solution depending on the type of material
residue to be removed from the instrument itself. Only use undiluted detergent if it is explicitly
specified in the product's instructions for use. Always follow the instructions for use of the solution.
Do not overfill the Ultrasonic Cleaner. Always place the instruments in a logical manner at the
bottom of the stainless steel basket, place the basket in the tank and proceed with the appropriate
cleaning. Too many instruments cleaned simultaneously will reduce the effectiveness of cleaning and
if touching, could lead to damage.
When objects are very dirty, use longer cleaning times.
When to replace the cleaning solution. It is recommended that the cleaning solution is replaced at
the end of every session, or as a minimum daily, unless local guidance recommends a more frequent
schedule or if the solution is heavily contaminated.
