Need to generate bubbles or microbubbles in a controlled way?


Our expertise:

On the basis of numerous challenging experiences to fulfill our customers' requirement, we have built up a wide expertise in the study, the development and the experimental qualification of specific solutions for bubbles and microbubbles generation.


For several years, we have been supporting industrials, university and private laboratories in the development of facilities for the generation of bubbles and microbubbles adapted to their specifications.


From this unique know-how, we have developed several standard products that we market for multiple applications and more specifically for research and test laboratories:

  • Low frequency bubbles injectors
  • Millimetric bubbles injectors

The generation of bubbles and microbubbles can induce needs for equipment intended to perform a liquid - gas separation function:


Liquid-Gas Separation

Our standard solutions:

We have developed 4 diffuser technologies covering a wide range of needs in the field of bubble and microbubble generation. Our generators offer controlled operating conditions, in particular with regard to bubbles diameter and injected gas flow rate.


The generation of gas microbubbles by CARMIN generator requires a high pressure water flow to produce a cavitation pocket. A controlled gas flow is then injected into the attached vapor cavity. The gas then breaks up into a cloud of very finely dispersed microbubbles.


Our LAMYLEC injectors are dedicated to the generation of trains of perfectly calibrated microbubbles, with adjustable bubble sizes and production rates.

These devices are mainly dedicated to very specific laboratory applications, such as:

  • calibration of measurement techniques and microbubble detection sensors
  • cavitation nuclei seeding
  • interaction of microbubbles with flat or textured solid surfaces, or with liquid-gas interface


The CIMYLEC device generates a "conical" plume of microbubbles induced by the turbulent fragmentation of a controlled gas flow by a high velocity liquid flow.

Low frequency bubbles injectors:

The low frequency bubble injectors generate millimetric bubbles with adjustable size and frequency. Unlike other technologies presented above, this solution does not require liquid flow for the formation of bubbles.

Millimetric bubbles injectors :

The millimetric bubbles injector generates perfectly calibrated millimetric bubbles (> 1 mm), with controlled production rates (> 1 bubbles/s). No liquid pump is required to generate bubbles, only a pressure gas source is needed.

Moreover, this injector can be assembled in a linear rail of multiple modules.
