Abstract

The invention provides a process for producing microbubbles using a T-junction device which includes a junction; a first capillary, connected to a gas supply; a second capillary, connected to a liquid supply, and arranged perpendicular to said first capillary, and a third capillary, wherein said first, second and third capillaries are connected to said junction, and in use, gas and liquid enter the junction, through said first and second capillaries respectively, producing microbubbles which leave the junction via said third capillary.
