What is TDS in water? Total dissolved solids (TDS) is the term used to describe the inorganic salts and small amounts of organic matter present in solution in water. These salts dissociate in water to form ions which means it has two parts: one with a positive charge and one with a negative charge, which […]

Differences Between RO and DI Water for Parts Cleaning, Washing and Rinsing
When using aqueous part cleaning systems and parts washers, rinsing the parts with high-grade RO (Reverse Osmosis) or DI (Deionized) water is often overlooked but is imperative to ensuring your final cleaned parts are fully cleaned and spot free. A DI water rinse provides the highest grade of quality for your precision cleaning applications. The […]
Nitric vs. Citric Passivation of Corrosion-Resistant Stainless Steel & Titanium
What’s the Difference? Nitric Passivation Citric Passivation Comparison Chart Nitric vs Citric Acid Passivation: What’s the Difference? Many people ask about the differences between nitric acid and citric acid for passivating parts made of stainless steel (SS), titanium (Ti), and other alloys. Both nitric acid and citric acid are effective in passivating many grades of […]
CitriSurf – Citric Acid Passivation Solution – Stainless Steel Material Compatibility Charts
Benefits Industry Standards Process Steps Testing CitriSurf Applications What is citric acid passivation? Citric acid passivation is the use of citric acid to passivate stainless steel (SS) and other alloys to prevent corrosion. By removing free iron ions and forming a protective passive oxide layer on the surface, the stainless steel or other metal becomes […]
How Do Ultrasonic Cleaners Work? How to Identify Quality Differences in Ultrasonic Cleaners
How Do Ultrasonic Cleaners Work? What to look for in Ultrasonic Cleaners How Are Best Technology’s Ultrasonic Cleaners Different? Ultrasonic Tank Myths How does an ultrasonic cleaner work? Ultrasonic cleaning works through high-frequency sound waves transmitted through liquid to scrub clean the surface of immersed parts. The high-frequency sound waves, typically 40 kHz, agitate the […]
Agitated Immersion Multi-Tank Passivation Systems
System Description Common Applications Common Configurations Agitated immersion tanks are used for passivation as they are designed for precision cleaning using water based detergents and citric acid. Multi-Stage Passivation System Ultrasonic Wash – Rinse – Acid Passivate- Rinse – Dry System Agitating parts washers and systems use a simple yet rugged designed pneumatically powered reciprocating […]
Ultrasonic Automated Passivation Equipment
System Description Common Applications Common Configurations Our automated ultrasonic passivation equipment using nitric or citric acid perform an automated process of cleaning-rinsing-passivation-rinsing-drying by moving the fluids from heated storage tanks into a single ultrasonic process tank, rather than moving the parts basket through a series of tanks. With this passivation machine, the entire process required […]
