Principles and fundamentals applied to the product functioning
Cleaning occurs by cavitation, reaching uniformly throughout the material to be clean, even in
hard to reach places.
This occurs through an ultrasonic vibration generator, where a eld test is subjected to a vibration
in high frequency when immersed in liquid solution.
The vibration generates a negative pressure causing the emergence of micro bubbles in the liquid
and a positive pressure providing the collapse of these bubbles on the surface of the proof body
forming micro jets that are responsible for erosion and cleaning eect.

Ultrasound equipment for cleaning medical and dental instruments and accessories composed of:
Injected body in ABS;
Control panel with digital display;
Transparent and removable viewer cover,
Tank made of stainless steel bowl and plastic basket;

Cleaning methods
Indirect clearing
Regular cleaning Appropriate places: Optical stores, laboratories chemical
and dental clinics.
Cleaning methods:
1. Add water to the cleaning tank to a level between the
lines "MIN" and "MAX" and above the object.
2. Place the objects to be cleaned inside the basket and
place the basket inside the tank.
3. Turn the main switch on. Press the TIME button to set the
clock between 5 and 10 minutes.
Press the On/O button once to start the cleaning.
Notes on the use of the basket:
1. The basket reduces friction between the objects and the
tank, but absorbs about 30% of ultrasonic energy reducing
the cleaning eect.
2. A metal basket absorbs less ultrasonic energy (about 8%).
Use tap water, chemical solutions are unnecessary in most
cases.
Place objects in a separate container. Use ultrasonic waves
to penetrate the container and to clean.
Appropriate places: Print shops, dental clinics, technical
assistance of mobile phones and electronics.
Dierent industries use dierent uids to be used inside the
containers:
1. Sterilization of medical instruments - Special Solution
(cleaning before sterilization).
2. Precision parts - Hexane (to dissolve fat to evaporate
quickly).
3. Technical assistance for mobile phones and electronics -
pure alcohol (to evaporate quickly).
4. Print shops - Acetone is often used (for dissolvingthe paint).
Do not allow contact between acetone and the plastic parts
of the equipment to avoid corrosion.
Use indirect clean and a glass or metal container for acetone.
We inform that the Bio Free Ultrasonic Washing Machines present outstanding results when
it is used only water in the cleaning process, however, in case any customer wishes to use
enzymatic detergents during the process there is no contraindication of it.
This model is equipped with a large tank. When cleaning small objects, the method of
"indirect cleaning" can be used with satisfactory results. Ultrassonic cleaners can also
do the job.
