ABSTRACT:
In accordance with a method of and an arrangement for producing lipid vesicles from biological membranes or lipid suspensions, a lipid suspension or lipid particles in a dispersion fluid are accommodated in a treatment container, ultrasonic treatment of the same is performed in condition of a substantially constant temperature, ultrasonic frequency and intensity for providing a desirable size or size distribution of the lipid vesicles are determined, and these parameters are maintained constant by measuring an actual value of frequency and intensity of an ultrasonic field of the reaction medium and adjusting a power and frequency of the ultrasonic treatment in dependence upon the measured actual value.
