Inhalation Exposure Research

Inhalation Dosing Towers ensure that simultaneous exposure of compounds or gases to the lungs of rodents is well controlled, consistent, and defined. It is crucial that researchers calculate an accurate measurement of the inhaled drug, which is derived by knowing the concentration of the drug delivered as well as the animal’s minute volume.  Most systems use an assumed minute volume value based on animal species and mass; DSI’s inhalation tower provides the ability to integrate plethysmography, allowing for direct minute volume measurement, eliminating the need to make assumptions.

Inhalation towers are used in a variety of research disciplines.

  • Inhalation toxicology - study pharmaceuticals, chemicals, and animal health
  • Biodefense Aerobiology - Infections disease, vaccines, and anti-terrorism research
  • Pharmaceutical and contract research organizations – assess the impact of a compound on major organ systems or evaluate the safety of new drug candidates
  • Discovery and Academic – focus on studies for the proper treatment of respiratory diseases
  • Environmental Toxicology – evaluate respiratory health hazard of airborne particulates

Inhalation / Exposure Tower - The DSI Buxco inhalation exposure system is designed with the ease-of-use desired by researchers new to inhalation exposure, yet providing the performance and flexibility required by the inhalation exposure expert. Unique to DSI is the ability to perform accurate real-time respiration monitoring during exposure, critical for animal welfare and determining accurate deposition levels.
