The LabGard ES 427 Biological Safety Cabinet may be used for work with minute quantities of volatile chemicals and tracer amounts of radionuclides if it does not interfere with the work in the re-circulated downflow.
The NU-427 contains an exhaust interlock system that prevents operation of the internal supply blower unless the exhaust flow is sufficient to provide the correct air barrier inflow velocity at start up.
TouchLink2 Electronic Control System
An easy to use color touch screen operates all system functions.
IntelliFlow Airflow Control
Assure optimal biological safety cabinet performance by monitoring, displaying, and controlling real time airflow with the same methods of you annual certifier with a dual thermistor airflow sensors powered by measurement instrument company TSI™ controlling downflow and a pressure flow grid controlling exhaust flow.
Night setback system allows for an energy saving sterile working environment when the cabinet is not in use.
Monolithic Pressure Tight Construction
A single shell, high grade stainless steel, fully welded cabinet eliminates potential leaks that may occur through failures of gaskets and cabinet seams.
Energy Saver Motor
NuAire ultra-high efficiency motor technology lowers energy costs while increasing filter life from the NSF minimum requirement of 50% (3 year equivalent life) to 300% or higher (10 or more years).
Unidirectional airflow moving along parallel flow lines at a constant velocity of 60 fpm (0.30 m/s) minimizes air turbulence within the work zone lessening the chance for cross contamination.
Dynamic Air Barrier
Strong inflow air velocity of 105 fpm (0.53 m/s) over an aerodynamic airfoil creates maximum personnel protection.
HEPEX™ Zero Leak Airflow System
The HEPEX™ plenum inflates to provide quiet uniform air without transferring vibration. Positive pressure chambers and ducts are surrounded by negative pressure eliminating potential leaks. HEPEX™ fabrics are incredibly durable. They are flameproof, provide a barrier against water, gases, fluid, and dust as well as resist to chemicals, oils, and greases. It even holds antibacterial properties and is impregnable meaning harmful materials become trapped in the filters.
