Nose-only Inhalation Exposure System for Small Animals (NOE),Tow-int_specification/price/image

Product Detail
Company Profile

Product Description (NOE)
The small animal nose-only exposure system is suitable for nose-only administration and inhalation exposure experiments on mice, rats, guinea pigs, and other experimental animals. The system has good air tightness and uniform exposure concentration. It is suitable for nose-only inhalation contamination experiments of inhalable substances such as liquid aerosol, dust aerosol, nanoparticle aerosol, and smoke. The system can ensure the consistency of the inhaled exposure dose of animals in the same experimental group, realize online concentration detection of aerosols and real-time online sampling, and adopt a high-precision control system to ensure the uniformity and stability of exposure.
The animal exposure system can test various substances, including drugs, air pollutants, PM2.5, organic substances, industrial hygiene, agricultural chemicals, etc. It can carry out acute and chronic contamination, hypobaria, hyperbaria, hypoxia, hyperoxia and other gas exposure experiments.

Features
· Double-chamber Design of Exposure Tower
Experimental channel: standard 24-channel configuration, 12 channels per layer, divided into upper and lower layers. Stackable upgrades are possible
Each layer is removable for easy cleaning
Material: Stainless steel
It has a double-chamber design; the inner chamber is a drug aerosol, and the aerosol is directly transported to the channel; the outer chamber collects the exhaled gas of the animal. Separation of inner and outer cavities to prevent re-inhalation of exhaled air by animals
· Aerosol Monitoring and Control
Comprehensive monitoring of environmental indicators and system operation indicators
Monitoring indicators: temperature, humidity, oxygen concentration, carbon dioxide concentration, pressure, drug concentration, aerosol particle size distribution (optional), etc.
· Exhaust Gas Treatment & Poisoning Chamber
It has a professional multi-stage exhaust gas treatment module, and the exhaust gas can meet the laboratory safety emission requirements after treatment. Provide a contamination chamber to ensure the safety of experimenters
· Security Alarm
Environmental indicators abnormal alarm: too low oxygen concentration, too high carbon dioxide will lead to animal death. When the set safety is exceeded, the system automatically starts an alarm. Alarm setting parameters: oxygen concentration, carbon dioxide concentration, temperature system abnormal alarm.
· Supported Infected Sample Sources
Support liquid aerosol generator, dust aerosol generator, nanoparticle aerosol generator, PM2.5 enrichment and generator, cigarette smoke generator, SO2/ozone/NO2 gas, pollen, etc.
· Applicable Animals
The small animal nose-only exposure system designed by TOW-Int Tech is flexible in configuration and provides animal immobilizers of different sizes. Standard with mouse, rat/guinea pig accessories, optional components for dogs, rabbits, NHP, and other animals. TOW-Int Tech specializes in providing various experimental animal inhalation drug administration and exposure programs and tailors various exposure systems according to users' needs, including animal systemic inhalation exposure systems, animal oral and nasal inhalation exposure systems, and cell exposure systems, contamination systems, etc.
