Our customers use thick-walled, long-conical nozzles to concentrate ionised gases under high pressure accurately to a point. Our aim for the design of the nozzles was, to create at most a long-concial line inside the nozzle. The nozzles consist of a long thick-walled body, which continues in ratio between wall-thickness and inner diameter to the tip. This enables a maximum of stability and pressure resistance. The inert glass material allows the concentration of hot gases, without contaminating them, by reaction with the nozzle.
