1. A nozzle assembly for high-frequency supply of a predetermined volume of a dosing fluid, up to maximum volumes of the dosing fluid of 1.0 ml, in liquid containers, wherein the high-frequency supply is performed at a frequency of at least 5 dispensations of the predetermined volume of dosing fluid per second,
wherein the nozzle assembly comprises a multiplicity of dosing channels extending in a same direction for the joint discharge of the predetermined volume of the dosing fluid, in which the dosing channels comprise a maximum internal diameter of 1.0 mm, and
wherein the internal diameter of the dosing channels is constant along the dosing channels and is at least 0.7 mm,
wherein at least some of the dosing channels extend at different angles with respect to each other, with at least a first group of said dosing channels oriented such that the extensions of said first group of said dosing channels converge in a convergence point on a distal side of the nozzle assembly, the nozzle assembly having at least 6 dosing channels,
wherein the dosing channels extend independently of each other at distal ends thereof in separate hollow tubes over at least 4 mm, wherein the distal ends are open and are positioned at a minimal mutual distance of 0.8 mm from each other, wherein at least one of the dosing channels forms an angle of at least 5° with respect to a mean direction of all dosing channels, and wherein at least one of the dosing channels forms an angle of at least 10° with respect to the mean direction of all dosing channels.
