Abstract

Liquid ejection device. The invention relates to a device (1) for dispensing liquid comprising a tip portion (1) made of a dielectric material with an electrical conductivity of less than 10⁻¹⁰ S / m. The tip portion (1) has an outer surface (4) shaped like a cone or pyramid, comprising an axis (2) and a vertex (3). The outer surface (4) of the tip portion (1) forms a semi-angle of between 10 and 49.8° with respect to the axis (2). The vertex (3) of the outer surface (4) is solid with the rest of the outer surface (4) and has a radius of curvature of less than 5 μm.
