2. Nose-only Inhalation Exposure Chamber

2.1. Complied with OECD, EPA, ISO10808 design standards, the chamber is suitable for liquid, dry powder, gas and other test substances.
2.2. With 12 animals per layer, the chamber is suitable for rats, mice, and guinea pigs; It can provide accommodation for up to 72 animals.

*2.3. The uniformity of the sample distribution of each animal port should be verified by computer numerical analysis. Relevant analysis data and reports should be provided.

#2.4. The chamber and its main parts are made of SUS316L medical-grade stainless steel ensuring its surface chemically anti-corrosive and can be sterilized under high temperature and high pressure.

2.5. The animal ports adopt a conical design to ensure a constant sample concentration in the breathing zone.

#2.6. Pressure difference, temperature, humidity, oxygen, carbon dioxide and other parameters can be detected. Installed sensors do not occupy the space of any animal hole. TrueBZS sampling technology can be applied to obtain environmental data in animal breathing zone.

2.7. By using an inner and an outer cavity, the intake and exhaust gas can be well separated. Both the cavities and the aerosol nozzle can be disassembled and cleaned independently.

2.8. The exposure chamber can rotate freely at the time of loading and unloading animals without affecting the exhaust pipe.
#2.9. Small support trays are equipped to carry the animal restrainers and collect animal excrement. Each tray can be replaced independently, and is compatible with a variety of animal restrainers.

2.10. A variety of aerosol generators and detection instruments can connect with the chamber where liquid, dust, and gas samples are tested, just by replacing the adapter.

#2.11. A constant pressure controlling method is adopted to ensure the uniformity of aerosol concentration and the particle size distribution of each animal port.

2.12. A flow-sharing design in the exhaust gas collection base is used to ensure the stability of the exhaust gas flow in the chamber.


3. Digitalized Controlling Unit

*3.1. High-quality imported controlling devices, components and sensors are used to ensure that the real-time monitoring and data recording of a series of parameters can be achieved, such as air source pressure, chamber oxygen, carbon dioxide concentration, temperature and humidity, chamber pressure difference, filter pressure difference, cabinet pressure difference, and external analog signals; The real-time controlling and monitoring of the following units can also be attained: aerosol generation flow, dilution flow, sheath flow, main gas path, dilution bypass gas path, flushing gas path, cabinet lighting and exhaust gas treatment unit.

#3.2. Upgradable and expandable without any damage of the equipment. Extra signal input and output ports can be added according to the needs of experiments.

3.3. Ethernet enables equipment networking and the access to the laboratory network to achieve centralized monitoring remotely.
#3.4. The controlling unit offers an independent touch screen which is a man-machine interface, as well as physical controlling buttons and indicating lights for main functional modules. All these facilitate the quick operation. Emergency shutdown apparatus and emergency programs are available as well.
