NU427-400 Features

This B1 biosafety cabinet is carefully designed to handle work involving small amounts of volatile toxic chemicals or trace radionuclides. It ensures safety by directly exhausting these substances when used in the appropriate portion of the cabinet.

When recirculated in the downflow air, the system minimizes interference, allowing seamless microbiological studies. This dual functionality makes it versatile and reliable for complex laboratory applications.

These ventilated workstations offer positive pressure and three-sided enclosure, ensuring maximum containment and sample protection. They are ideal for microbiology, toxicology, and research labs, providing a safe and controlled workspace. The system draws air inward at a minimum inflow velocity of 100 ft/min, passing it through a HEPA filter. Finally, all air is safely exhausted outside through another HEPA filter and connected HVAC ductwork, preventing environmental contamination.
