Decontamination chamber is successful in combating a broad variety of viruses and microorganisms. It is less damaging than an autoclave to laboratory equipment, and demands less power. Decontamination chambers usually employ hydrogen peroxide, chlorine dioxide or formaldehyde generators. The media generated is introduced into the chamber via a specially adjusted nozzle system with impulse control and integrated heater. The introduction takes place as intensely as possible and with quick even distribution. This assures an even and quick introduction into the chamber.
