The DBMM-1M module
Controlled interaction experiments for drops, bubbles and thin liquid films.
The DBMM-1M extends the PAT-1M with direct interaction measurements between two drops, two bubbles or mixed drop–bubble systems. By precisely controlling the distance between both interfaces, the module enables detailed observation of film formation, deformation and coalescence.
In addition to direct interaction studies, the system can measure dynamic surface and interfacial tension using capillary pressure. External perturbations can also be applied to investigate the stability of liquid films under defined experimental conditions.
