Ultrasonic cleaning and "indirect" cleaning.
Auxiliary tank and beakers
What is the difference between the ultrasonic "direct" cleaning and ultrasonic "indirect cleaning"?
Direct cleaning occours when the parts are cleaned directly in the ultrasonic cleaner filled with the cleaning solution.
Generally the parts to be cleaned with ultrasounds are inserted in a stainless steel mesh basket. The limitation of direct ultrasonic cleaning is the selection of the appropriate cleaning solution that will not damage the ultrasonic cleaner.
