Description
The system is used to conduct nose-only inhalation toxicity tests for rodents, including multiple concentration bioaerosols, chemical aerosols and smoke, etc. It can ensure inhalation dose consistency of the same test group, realize online monitoring of aerosol concentration and real-time sampling, and achieve the leading level of exposure uniformity and stability through a high precision control system.
Features
- Realize inhalation exposure test of homologous gases, vapors or mixtures with 3 to 5 concentration gradients.
- Unique vortex mixing and dilution technology makes the concentration of inhalation test substances uniform and stable for all layers’ animals. The uniformity and stability deviation of each exposure port's mass concentration during tests for gas is within ±8%, for liquid aerosol is within ±10%, while for dust aerosol is within ±20%, which conforms to technical requirements of OECD inhalation guidelines.
- Negative pressure protection system can guarantee the safety of personnel.
- Space-saving, low energy consumption and sample consumption.
- Max. 5 times concentration gradient can be realized.
