Guardian Class 1 Biological Safety Cabinet Monmouth ■ High-Quality HEPA Filters ■ Optional Ducted Extract ■ Infra-Red Intelligent Sash Safety ■ Airflow Safety Monitoring Guaranteed Personnel & Environmental Protection Solution The Guardian Class 1 Biological Safety Cabinet offers optimal protection for laboratory personnel and the environment when handling hazardous biological materials. Designed to comply with EN 12469:2000 standards, the Guardian provides a safe working environment for various applications, including microbiology, virology, and molecular biology. It is ideal for procedures where operator protection is critical, ensuring contaminants are contained effectively while maintaining an efficient workspace. The Biological Safety Cabinet operates by d ra wing air away from the operator, creating an airflow barrier between the user and the h azardous materials. Contaminated air is filtered through a high-efficiency particulate air [HEPA] filter before being safely exhausted, ensuring that h ar m f u l agents are contained within the cabinet.
