During a typical study the subject is placed in its own exposure tube. A rubber seal around the animal's neck ensures an airtight seal in the body of the exposure tube. Each tube is placed in the exposure tower, and aerosol is then administered to all the animals simultaneously. The exposure tube is equipped with a pneumotachograph, which allows measurement of respiratory flow from movement of the animal's chest wall.
