Cavitation
The foundation of ultrasonic cleaning occurs when ultrasonic energy is introduced into a
cleaning solution. This energy causes alternating low and high pressure phases. During low
pressure phases, minute bubbles (or vacuum cavities) are formed: during high pressure phases,
bubbles implode violently.
Chamber
Large cavity within equipment where instruments are washed. Also refered to as "tank".
Chemical
A water-soluble substance used to assist cleaning during a wash cycle. Often refers to the use
of "detergent".
Chemical pickup
Hose assembly that connects to chemical port at the back of the sonic irrigator and is fed into a
chemical bottle. The hose assembly provides chemical (detergent) to the sonic irrigator as
demanded by wash settings.
Chemical pump
Internal pump used to deliver detergent into the tank.
Concentration
A measure of the amount of dissolved substance contained per unit of volume.
Cycle
A sequence of actions that equipment performs in order to clean instruments. Also referred to
as a "program".
D
Degas, Degassing
An action where sonics are used to remove dissolved gases of water in tank. Degassing is
normally performed at beginning of main wash cycle stage.
