Guide and selection support
Ultrasonic baths are primarily used in the laboratory for thorough cleaning of glassware, pipettes, and ground joints, as well as for sample preparation and solvent degassing. The selection depends on the bath volume, frequency range, power output, and additional features such as temperature control, according to the intended application and required level of cleanliness. LabFinder supports the search for the right ultrasonic baths with specific filter options, providing guidance on application areas and technical specifications.
Application and Benefits
Ultrasonic baths are used in laboratories to intensively and gently clean glassware, pipettes, burettes, and other delicate instruments. Ultrasonic waves generate cavitation, allowing the cleaning liquid to reach even hard-to-access areas. In addition, ultrasonic baths are used for solvent degassing, especially in HPLC, and assist in emulsification, homogenization, and sample dissolution processes during sample preparation.
Selection Criteria
Important selection parameters include the size of the bath volume, the ultrasonic frequency (typically in the range of 25 to 40 kHz), power output, and temperature control. The material compatibility of the bath interior and the compatibility with the samples to be cleaned are also relevant. Additional features such as timers, digital displays, or ultrasonic pause functions can be important depending on workplace requirements.
Variants and Measuring Principles
Ultrasonic baths operate on the principle of cavitation, where sound waves create pressure fluctuations in the liquid. Differences exist in frequency and power output, tailored to various applications. Manual or automatic controls allow adjustment of process parameters. In laboratories, most devices are bath cleaners with ultrasonically assisted cleaning and dispersing functions.
Calibration and Maintenance
Regular cleaning of the inside of the ultrasonic bath and replacement of the cleaning medium are important to maintain cleaning performance. Function testing of the ultrasonic system is recommended to ensure constant output. Follow the manufacturer’s instructions for technical maintenance to achieve long service life.
Application Limitations
Sensitive or structurally unsuitable materials may be damaged by ultrasound. The effectiveness depends on the medium and degree of contamination, meaning some impurities may not be completely removed. Ultrasound alone does not replace chemical cleaning for strong organic or inorganic residues.

Frequently asked questions
How does an ultrasonic bath work in the laboratory?
The ultrasonic bath produces high-frequency sound waves that cause cavitation in the liquid. These tiny bubbles implode and mechanically remove contaminants even from hard-to-reach spots.
What types of ultrasonic baths are available for laboratory use?
Ultrasonic baths mainly differ in volume, frequency range, and power output. Some devices offer additional features such as temperature control or digital operation.
What should be considered when selecting an ultrasonic bath?
Key factors include bath volume, frequency, power, temperature control, and compatibility with the materials to be cleaned.
For which laboratory applications is an ultrasonic bath suitable?
Mainly for cleaning glassware, degassing solvents in HPLC, emulsification and homogenization processes, and sample dissolution during preparation.
What are the limits of ultrasonic cleaning in the lab?
Ultrasound can damage sensitive materials and does not always replace chemical cleaning agents for heavy contaminants. Cleaning efficiency depends on both the medium and the object to be cleaned.
