Inhalation Exposure System
The Inhalation Exposure System provides reliable, repeatable exposure.
Provides reproducible exposure to droplet-borne contaminants and infectious agents.
Produces deep-lung infections that more closely simulate real-world circumstances.
Allows user to vary pathogen concentration, rate of air flow, and length of exposure.
Uses improved filtering, an air incinerator, and ultraviolet lamps to aid in decontamination.
Offers increased efficiency through the use of an Allen Bradley programmable control.
How the inhalation Exposure system work
The inhalation exposure system is a whole body exposure chamber for the quantitative experimental infection of animals by inhalation of air bearing the pathogenic agent. The heart of the system is the nebullizer-venturi unit into which the suspension is introduced. Air under pressure atomizes the suspension, which is mixed with filtered room air drawn into the system by suction beyond the decontamination system. By varying the no. of micro-organism in the suspension, the proportion of bacteria bearing nuclei can be varied. The system permits control of the volume of air moving through the chamber per unit time.
The animals are placed in a compartmented mesh basket within the chamber. Compressed air and vacuum pumps, along with the necessary controls and flow indicators, are built into the system. A programmable control is used to the time the preheat, nebulizing, cloud decay, and decontamination periods. A filter and ultraviolet lamps are provided for cleaning the system.
New system improves safety
Improved filtering and ultraviolet lamps aid in the decontamination of the system, therefore improving operating safety. And for additional safety, the system operates under negative pressure.
New control increases efficiency
The inhalation system is equipped with an Allen Bradley programmable control. This sophisticated control is highly functional, very easy to use, and increases the efficiency of the system. The control's visual display screen allows you to read what process is taking place.
