Head-Nose Exposure Towers

Modular Configuration: We offer a range of Head-Nose exposure towers specifically designed for inhalation studies in rodents and large laboratory animals, like dogs or non-human primates. These towers feature a modular design, allowing researchers to configure the system for studies involving 8 to 96 animals simultaneously. Large animal towers offer adaptability, allowing exposure and real-time individual concentration analysis for up to 4 animals at a time.

Flow-Through Design: The towers employ a sophisticated flow-pass design that guarantees uniform distribution of test substances throughout the exposure unit and avoiding an exhaled air rebreathing. This ensures consistent exposure across all animals within the system, minimizing confounding variables and enhancing data quality.

Environmental Monitoring: Beyond exposure control, our towers offer the option to integrate environmental sensors for real-time monitoring of critical parameters. These sensors measure temperature, humidity, oxygen (O2) and carbon dioxide (CO2) levels, and pressure. This monitoring plays a vital role in maintaining experiment integrity and optimizing animal welfare.

Our System Modular and Extendable Architecture.

Together we are working on system configuration to meet study design requirements, safety assessment protocols and methodologies for measuring the properties of the tested substances.
