Abstract
The invention relates to a device for producing lipid vesicles, which is equipped with a line () for transporting a polar liquid phase, with a line () for transporting an organic liquid phase containing lipids, with a collecting receptacle () for accommodating produced lipid vesicles, and with means for conveying the liquid phases through lines () and (). At at least one location, the outer side of line () forms a common contact surface with line () inside of which a common opening () is provided that permits the flow of liquid and joins the inside of line () to the inside of line (). Lines () and () do not contain agitating or dispersing aids in the area of the opening (). The invention also relates to a method for the careful production of lipid vesicles, wherein the lipid phase is sprayed under pressure perpendicular to the direction of flow of the polar phase and into the same, whereupon lipid vesicles having a narrow size distribution form spontaneously and without the action of mechanical agitating or dispersing aids.
