Ultrasonic cleaning device for removing undesirable particles from an object

A cleaning device for cleaning at least one object comprising:

• an inner vessel containing a first liquid;
• an external vessel containing a second liquid and the inner vessel, wherein the second liquid is acoustically coupled to the first liquid;
• and
• at least one transducer acoustically coupled to the external vessel and configured to generate acoustical energy which is transferred to the object;
• wherein the first liquid has a dissolved gas concentration of a first gas that is greater than a dissolved gas concentration of a second gas in the second liquid.

A cleaning device for cleaning at least one object comprising:

• an inner vessel having a first inner end and a second inner end and configured to contain a first liquid having a first fluid flow rate and the object, the first fluid flow rate configured to transfer the object from the first inner end to the second inner end;
• an external vessel having a first external end and a second external end and configured to contain a second liquid having a second fluid flow rate and the inner vessel, wherein the second liquid is acoustically coupled to the first liquid and the second fluid flow flows from the first external end to the second external end;
• and
• at least one transducer acoustically coupled to the external vessel and configured to generate acoustical energy which is transferred to the object;
• wherein the first liquid has a first dissolved gas concentration of a first gas and the second liquid has a second dissolved gas concentration of a second gas, the first dissolved gas concentration is different than the second dissolved gas concentration.
