LabGard NU-437S Class II, Type A2 Biosafety Cabinet

The LabGard ES NU-437S Class II Biosafety Cabinet monitors plenum pressure through microprocessor controls. Ergonomic design and cost savings technologies enhance the user’s environment while providing the proper biocontainment when working with cultures, viruses, and more.



  • Vertical Ergonomic Front Window

  • FlowGard Control System with Digital Monitor


*Available only in Asia

Part #: NU-437S

Features

FlowGard Control System
The microprocessor controls monitor plenum pressure providing audible and visual alarms for low and high airflow.

Energy Saver Motor
An ultra high-efficiency motor saves on your energy bills while increasing filter life lowering your total cost of ownership.

Experience Ergonomics
NuAire Biological Safety Cabinets provide maximum knee/thigh clearance that improves the users' ability to assume a proper posture. The maximum knee/thigh clearance is accomplished by a design improvement that reduced the plenum height beneath the work surface. 

An adjustable base stand provides the ability for laboratory personnel to optimize ergonomic conditions improving leg and forearm support. 

A heavy-duty plastic armrest minimizes cold conduction and provides additional forearm support.

Cool white lighting and a polished edge window reduce glare allowing for greater visibility and better sight lines to the effective work zone area reducing awkward posture resulting in less eye fatigue and/or neck strain. 

NuAire Biological Safety Cabinets provide the largest effective work zone area available which helps reduce arm/neck/shoulder strain.

Our ultra-high efficiency motor runs quieter with fewer vibrations creating less stress on the body.

Additional accessories such as an adjustable footrest, elbow rests, turntable, and ergonomically designed chair enhances the user’s ergonomic working environment.


TruLaminar Airflow
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 resistance to chemicals, oils, and greases. It even holds antibacterial properties and is impregnable meaning harmful materials become trapped in the filters.

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.

Attenumount
Vibration and sound control
