This exposure system is designed to simulate the low oxygen pressure environment and the inhalation toxicity of test sample can be studied under such environment.

Our exposure systems are suitable for long- and short-term inhalative investigations with test animals involving toxicity and impact of particulate matter, e.g. in pharmacology, environmental and occupational safety, and bio-defense studies.

The exposure system design and inhalation software for automatic control and regulation of experiments support you in achieving compliance with the OECD, GB and GLP guidelines.

1. The units are available in different designs and sizes according to the test requirements. The number and type of connections can be specified at the planning stage.

2. Our exposure units allow the simulation of real exposure conditions for a wide range and large numbers of rodents, either under static and / or dynamic conditions.

3. Provision of water and additional sample ports can be implemented where required.

4. Robust stainless steel design with standard and customer-specified sealing materials.

5. Test substance supply is possible via various liquid, dust aerosol generators, cigarette smoke generators as well as vapor generators.

6. Different standard sizes of stainless steel cages or cage racks.

7. Real-time and off-line analysis equipment – concentration measuring units and spectrometers.

8. Control and monitoring, data recording and storage through the in-house software.

9. Installation kit to connect air supply, aerosol and vapor generators, exhaust lines and sampling equipment.

10. Equipped with safety shield cabinet to protect the safety of the experimental personnel.

11. With memory function in case of power-down.
