5. "Why is there a high pitch sound coming from the BioSonic UC150?"
When a unit is initially filled up with a fresh solution mix there are lots of bubbles in the solution.
If the unit is turned on right after fresh solution is added to the tank, it may make a screeching
sound. Additionally, when placing a basket with instruments into the solutions, air is introduced
and dissolves in the solution, which may create a screeching sound. The noise is present in all
ultrasonic cleaners, but is a normal occurrence and is not an indication of any issues with your
device, simply that degas may be required.
To degas, please refer to the section of this manual that describes degassing in detail.
6. "What is degassing and why do I need to do this?"
Before cavitation can become effective in an ultrasonic cleaner the gas trapped in the liquid must
be removed. If it is not removed, the cavitation bubbles will fill with this gas, cushioning the
implosion force. To degas, refer to the section of this manual that describes degassing in detail.
7. "What solution should I be using?"
The purpose of the solution is to break the bonds between the instruments and the soil. Water
alone has no cleaning properties and has high surface tension, which inhibits the cavitation
bubbles from developing. Adding cleaning solution reduces fluid surface tension and contains
ingredients designed to optimize the ultrasonic cleaning process.
Liquid solution allows for instantaneous solution preparation where tablets and powder
solutions must be fully dissolved prior to beginning the cleaning process. It is recommended that
tablets and dry solutions be dissolved in hot water prior to placing them in the tank to prevent
them from settling on the bottom of the tank until the ultrasonic action dissolves them.
The BioSonic system offers a full line of cleaning solutions which offer the flexibility to efficiently
clean and disinfect instruments, prostheses, and other items. It is recommended that BioSonic
solutions be used with your BioSonic UC150 for consistent and effective performance.

8. "What can be cleaned using my Ultrasonic Cleaner?"
Ultrasonic cleaning is effective for most instruments such as:
• Dental burs which are reprocessable
• NiTi endodontic files
• Jointed instruments, e.g. scissors
• Stainless steel syringes
• Serrated instruments
