WHAT FREQUENCY IS BEST FOR ULTRASONIC CLEANING EQUIPMENT? WWW.SONICPRO.COM Choosing the right frequency is one of the most important decisions when selecting ultrasonic cleaning equipment . Frequency determines how powerful or gentle the cleaning action will be, directly affecting performance, safety, and efficiency. Frequency is measured in kilohertz (kHz), and most systems range from 20 kHz to 80 kHz. Understanding Frequency in Ultrasonic Cleaning Ultrasonic systems operate by producing high-frequency sound waves in a cleaning solution. These waves create microscopic bubbles through cavitation. When the bubbles collapse, they release energy that removes contaminants from surfaces. Best for: Heavy grease and oil Carbon buildup Industrial machinery parts Durable metal components Low Frequency (20–28 kHz): Strong & Aggressive Lower frequencies create larger cavitation bubbles that collapse with greater force. This range is ideal when deep, aggressive cleaning is required. Best for: Medical instruments Lab glassware Automotive components General manufacturing parts Mid-Range Frequency (35–40 kHz): Versatile & Balanced The most common frequency for general use. It offers a balance between cleaning strength and surface safety, making it suitable for many industries. Best for: Delicate electronics Fine jewelry Optical lenses Precision components High Frequency (68–80+ kHz): Gentle & Precise Higher frequencies produce smaller bubbles with less force. This option minimizes the risk of surface damage while still delivering effective cleaning. Which Frequency Is Best? There is no single “best” frequency for all applications. The right choice depends on the material, contamination level, and sensitivity of the parts being cleaned. Some advanced ultrasonic cleaning equipment even offers multi-frequency settings for greater flexibility.
