The benchtop ultrasonic citric passivation system processes medical device industry parts with precision part cleaning and passivation after machining and laser mark. The customer, Integrated Technology , is able to passivate the following grades of stainless steel: 17-4, 304 and 316 with a neutral pH alkaline cleaner and CitriSurf® 2250. Other stainless steel grades are possible with this system, but the customer has validated these materials.
The tabletop ultrasonic citric passivation system consists of a 9 gallon (tank dimensions: 18″ L x 12″ L x 10″ D) ultrasonic parts washer / cleaner with filtration and circulation, ultrasonic cascade overflow rinse tank, ultrasonic citric passivation tank with filtration and circulation, ultrasonic cascade overflow rinse tank, and a heated air parts dryer.

Since this system is made for citric acid passivation, the addition of circulation pumps that constantly run to aid in inhibiting any possibly organic growth in the tank which the chemistry’s built-in biocide should prevent. Constantly circulating / mixing citric acid greatly reduces the possibilities of organic growth over time.
