The invention relates to a method for capsulating microbial, plant and anima l cells or biological and chemical substances, using a nozzle to obtain small, especially spherical particles by vibrating an immobilisation mixture. According to said method, the immobilisation mixture, especially a laminar fluid jet taking the form of an immobilisation mixture, is divided into equa l parts by superimposition of an external vibration. In a device especially we ll suited to carry out this method a metallic counter-element (18) which is mounted downstream from the nozzle (16) at a distance (a) to, and on the outside of, the nozzle axis (A) is connected to a high-voltage source (30). The counter-element is to be embodied by a metal ring (18) through whose through hole (20) the nozzle axis (A) extends. The metal ring (18) is radial ly connected to an insulated support (22, 24). |
