AELAB AE-LAI-3T-N20 Anaerobic Incubator – Controlled Oxygen-Free Microbial Growth

The AELAB AE-LAI-3T-N20 Anaerobic Incubator is a precision-controlled system engineered for oxygen-free microbial cultivation. It supports the growth of anaerobic bacteria and other oxygen-sensitive microorganisms by maintaining a stable, inert environment with regulated gas flow, temperature, and humidity. This instrument is designed for research, clinical, and industrial microbiology laboratories where accurate anaerobic conditions are essential for reproducible results.

⚙ Design & Construction

The AE-LAI-3T-N20 features a spacious operation chamber with a transparent, impact-resistant window that allows clear observation of samples. The incubator integrates a large touchscreen LCD for real-time display of temperature, oxygen concentration, and operational status. A high-precision PLC controller ensures accurate regulation, while the oil-free vacuum pump and palladium catalyst maintain the anaerobic environment with minimal maintenance. The system includes internal lighting, power sockets, and UV sterilization for contamination prevention.

🔬 Working Principle / Testing Method

The AELAB AE-LAI-3T-N20 operates through vacuum-assisted gas replacement using a mixture of nitrogen and reducing gases to remove oxygen. The oxygen level is continuously monitored by an imported high-sensitivity sensor, ensuring operation room O₂ levels remain below 5 ppm. Once the anaerobic state is achieved, the incubator maintains it for over 13 hours without additional gas supply. The system’s automated pressure control and positive/negative protection mechanisms ensure stable sample handling and prevent air ingress during transfer.

💡 Key Advantages

• Direct oxygen concentration display via touchscreen for continuous monitoring
• Automatic gas replacement with programmable oxygen percentage settings
• Data logging through USB interface for up to 6 months
• Oil-free vacuum pump and palladium catalyst for efficient oxygen removal
• Integrated UV lamp and lighted interior for aseptic manipulation
• Ergonomic design with removable front cover for easy equipment placement
• Safety protection systems including power leakage and pressure relief design

🔗 Connectivity & Integration

The AE-LAI-3T-N20 supports data transfer through a USB port, allowing laboratory information management systems (LIMS) integration and long-term storage of process parameters. Automated air replacement and gas control functions can be configured for different anaerobic protocols, simplifying workflow standardization.
