Inhalation Exposure System

Description

The Glas-Col Inhalation Exposure System is a whole-body exposure chamber used for the controlled inhalation of airborne pathogens or contaminants in animal studies. It enables reproducible experimental infection by allowing precise adjustment of aerosol concentration, airflow rate, and exposure duration. The system incorporates a nebulizer-venturi unit to atomize agent suspensions, which are then mixed with filtered air and drawn into a 5 cubic foot chamber. A compartmented mesh basket holds subjects, with capacity for approximately 100 mice, 15-20 guinea pigs, or five rabbits. Integrated controls manage a programmable cycle including preheat, nebulizing, cloud decay, and decontamination phases, with default timers adjustable via keypad. Safety features include UV lamps and an air incinerator for decontamination. The unit operates on 120 or 240 V and supports an airflow range of 10 to 100 SCFM. It is applied in research requiring consistent, deep-lung infections that simulate natural exposure scenarios.
