<p>The device (1) has a tube shaped reservoir (2) including an outlet orifice and a gas generator (7) at its respective ends, where the generator is chosen from a group comprising chemical gas generator, pyrotechnical gas generator, hybrid gas generator or cool gas generator. The reservoir contains fluid e.g. aggressive fluid to be delivered, comprising a chemical tracer. A cylindrical piston is slid inside the reservoir along a longitudinal axis of the reservoir, in a sealed manner. The generator displaces the piston such that the fluid is rapidly delivered from the reservoir via the orifice.</p> |
