- Abstract
- An inhalation exposure system was designed from an all glass aquarium with a volume of 391 liters. A top for the chamber was fabricated from acrylic plastic and Teflon (surface in contact with the test atmosphere) with an inlet, outlet, 5 sampling ports, and handles. Supply air to the chamber was charcoal and HEPA filtered. Air flow through the chamber is horizontal and can range from 50 to 200 liters/minute. Air flow is measured by a glass tube rotameter and regulated by polyvinyl chloride valves. Chamber air was HEPA and charcoal filtered prior to exhausting it to ambient air.
