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.


Exhaust Interlock

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.

  • On/off for lights blower and interior outlets.
  • Monitors high/low limits for down flow inflow and sliding window position.
  • Password protection locks out unwanted changes to the system.
  • Date/clock display and timer function can be used as a laboratory timer to set purge cycles outlet timer UV light timer auto-run timer NiteCare night set back or weekend turn-off.
  • Filter status displays remaining filter life
  • Complete diagnostic functions for a NSF trained service technician or certifier.
  • NEW – BACnet RS-485 interface provides the Building Automation System (BAS) a two-way communication link to query the TouchLink2 operating information. View airflow data alarm status etc. and control TouchLink2 for facility energy savings by initiating NiteCare (Night Setback System).


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).


Experience Ergonomics – Over 640 muscles at work.

NuAire Biological Safety Cabinets are designed to create an ergonomically correct environment reducing user fatigue and work place injuries.  

  • Maximum knee/thigh clearance that improves the user’s 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 reduces 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 resist to chemicals oils and greases. It even holds antibacterial properties and is impregnable meaning harmful materials become trapped in the filters.
