IDENTIFICATION OF THE EQUIPMENT
Description of the Equipment
Principles and bases applied to the operation of the product
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 effect.
Medical, dental and laboratory instruments and supplies cleaning "removal of blood
and small particles on the instruments prior to disinfection". It should be used and handled
by qualied person (professional properly regulated, according to local legislation of the
country) following the instructions contained herein.
It is the user's obligation to use only the equipment in perfect conditions and protect
himself/herself, patients and others from possible dangers.
Indication of Equipment
