SONOREX ultrasonic baths and SONOPULS ultrasonic homogenisers are part of the equipment of every laboratory and are practically irreplaceable for cleaning laboratory equipment, sample preparation for subsequent analysis, emulsification or cell disruption. All products have one thing in common: they are focused on both the user and the processes involved in ultrasound. An application database has been built up on the basis of customer contacts. Information on the differentiated range of products and accessories was paired with an overview of detailed aspects for the various application areas. This makes it easier for users to start using the equipment successfully and supports a high quality of application. We are not only oriented towards what is needed in institutes or universities today. Our expertise, our close relationship to the users and our overview of the industry allow us to unerringly determine the needs in the laboratory sector and to bring product ideas to market maturity. This has enabled us to constantly improve and expand our portfolio. The design of the equipment is geared towards the long term.

For use in laboratories and technical centres, we produce ultrasonic homogenisers with accessories for the respective applications, both for routine operation and for use in research. research. The homogenisers have been used for over 25 years for sample preparation in waste water and soil analysis, for cell disruption emulsification, reaction acceleration or for the production of the finest emulsions. or for the production of extremely fine emulsions. Used in the laboratory ultrasonic baths are not only used to thoroughly clean laboratory cleaning of laboratory glassware, but also for the effective homogenisation of samples. samples.


Compact ultrasonic baths

The SONOREX high-performance ultrasonic baths are manufactured in series with or without heating.

Sample preparation

The samples available after sampling are usually not suitable in their original form for performing instrumental analysis methods on them. In sample preparation, the analyte must be converted into a homogeneously dissolved form by means of ultrasound.


Dispersing is the term used to describe the homogenisation of substances or also the optimal mixing. Dispersing by means of ultrasound achieves the ideal state of individually present primary particles that are wetted with binder.

Cell disruption

The cavitation bubbles generated by ultrasound create high shear forces that break up the cells. The desired degree of disintegration is set by varying the duration of the sonication.




The BANDELIN cleaning baskets are designed in such a way that the items to be cleaned are always in the optimum area of the cavitation field (1-2 cm from the bottom) in the tub.


A matching stainless steel lid for an ultrasonic bath protects the bath fluid from external contamination and prevents odours from the added cleaning or disinfecting preparations.

Special accessories

For the expansion of our ultrasonic baths, we offer suitable accessories for the fields of medicine, laboratory and industry.

Gases diffused into the cavitation bubbles from the liquid are released abruptly during the cyclic implosion of the cavitation bubbles and float up to the liquid surface. The liquid is degassed accordingly.


Ultrasonic homogenisation is a mechanical process to break up and distribute particles in a liquid so that a uniform, homogeneous suspension is produced.


Fine cavitation bubbles are generated in the cleaning fluid by means of ultrasound. The cyclic implosion of these bubbles on the cleaning object effectively removes contamination.
