Nose-only inhalation exposure system for small animals with single concentration

没有此类产品
The product description

 

The instrument can be used to complete Nose-only inhalation toxicity experiments of rodents (rats, mice, guinea pigs, etc.) on inhalable substances such as gas, liquid aerosol, dust aerosol, nanoparticle aerosol, flue gas, etc. Ensure the consistency of inhalation doses of animals in the same experimental group; Realize aerosol on-line concentration detection and sample real-time on-line sampling; The adoption of high precision control system makes the uniformity and stability of exposure reach the industry leading level. The gas mass concentration uniformity error between each inhalation exposure port is within ±8%, the liquid aerosol uniformity error is within ±10%, the dust aerosol uniformity error is within ±20%, and the aerosol long-term stability error is within ±20%.

 

 

01. In the field of drug safety evaluation

02.In the field of chemical and pesticide safety evaluation

03.The fields of inhalation immunization and environmental assessment

04.The field of respiratory disease modeling and efficacy evaluation

05.The field of radioactive material hazard assessment and protection

06.Military medicine and aerospace medicine

 

 

01.The Nose-only exposure chamber is of stainless steel double-cylinder structure, with positive pressure in the inner cylinder and negative pressure in the outer cylinder to ensure that the exhaust gas exhaled by animals does not pollute or dilute aerosol;

02.During the exposure process, the gas concentration uniformity error of each hole is within ±8% of the average value, the liquid aerosol mass concentration uniformity error is within ±10% of the average value, and the dust aerosol mass concentration uniformity error is within ±20% of the average value, which all meet the technical requirements of OECD TG, pesticide and chemical toxicity tests.

03.Negative pressure protection system ensures the safety of laboratory personnel;

04.The waste gas produced in the experiment completely meets the national safety emission standard after being treated by the filtration system.
