Biological Safety Cabinets

Biological Safety Cabinets

Thanks to NuAire’s commitment to advancing technologies in their range, we are able to offer the safest and quietest biological safety cabinets on the market.

Avidity Science has been the UK distributor and service provider for the NuAire BSC range for 15+ years.

The protection of scientists is of paramount importance in any laboratory environment. For the supply of biological safety cabinets, we supply double HEPA filtration technology which is featured in the NuAire BSCs, this gives you the confidence that you, your colleagues and your work is protected.

The NuAire Class 2 cabinets are equipped to do this with BSEN12469:2000 certification. BSEN12469:2000 sets the minimum performance criteria for safety cabinets for work with micro-organisms and specifies test procedures for microbiological safety cabinets with respect to protection of the worker and environment, product protection and cross contamination.

NuAire manufactures the highest quality Class 2 safety cabinets for the most demanding applications and are universally recognised as one of the world's leading providers, having designed and built the first modern-day Biological Safety Cabinet.

Avidity Science provide a full installation package with its team of national service engineers from the Avidity Science Service Solutions team in the UK, who can commission your Class 2 Safety Cabinets, and provide ongoing service support for years to come.

What is a Biological Safety Cabinet?

The primary purpose of a Biological Safety Cabinet is to serve as the primary means to protect the laboratory worker and the surrounding environment from pathogens. All exhaust air is HEPA-filtered as it exits the biosafety cabinet, removing harmful bacteria and viruses. This is in contrast to a laminar flow clean bench, which blows unfiltered exhaust air towards the user and is not safe for work with pathogenic agents. Neither are most Biological Safety Cabinets safe for use as fume hoods. Likewise, a fume hood fails to provide the environmental protection that HEPA filtration in a Biological Safety Cabinet would provide. However, most classes of Biological Safety Cabinets have a secondary purpose to maintain the sterility of materials inside.

Introducing the NuAire Series Biosafety Cabinet

The NuAire Class II Safety Cabinet offers environmental, personnel and product protection, thanks to its ultra high-efficiency ECM motor, ergonomic design and long-lasting filters. Each cabinet has gone through a series of quality-assurance tests to ensure maximum quality, safety and efficiency.

  • Airflow is 30% exhausted, 70% recirculated
  • 105fpm (0.53m/s) Inflow, 60fpm (0.30m/s) Down Flow
  • Auto filter loading compensation
  • Motor Speed Controller
  • Internal Exhaust Damper
  • Armrest for comfort during use
  • Stainless steel coved work tray and front intake grill
  • External fluorescent lighting (100lm/ft2)
  • HEPEX Zero-leak airflow system
  • Spill trough with drain valve
  • TUV NORD certified to EN 12469:2000 

HEPEX™ Zero Leak Airflow System

All LabGard® positive pressure plenums are surrounded by a vacuum relative to the room. Meaning in the event of a leak via gasket failure, all contaminated air in the plenum is still forced through HEPA filtration. The HEPEX™ system also works to provide true laminar airflow by evenly distributing plenum air over the supply HEPA filter. The flexible design eliminates any vibration transfer from the motor blower as well as creates a serviceable work environment for Certifiers after decontamination.

NuAire Class 2 Cabinets

True Laminar 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.

NuAire Class 2 Cabinets

Dynamic Air Barrier

A strong inflow air velocity of 105 fpm (0.53 m/s) over an aerodynamic airfoil creates a dynamic air barrier offering maximum personnel protection.

Ergonomic Design Reduces Workplace Injuries

The NU-543 offers a shorter reach into the work zone bringing work materials closer to you relieving stress on your arms, back and neck. A standard plastic armrest eliminates cold conduction on forearms relieving tendons of any unnecessary stress. A recessed airfoil allows technicians to use the armrest without fear of blocking airflow.

A further recessed work-tray with spill lip protection lowers the work zone making it easier for lab techs to use pipettes or creating additional space for machinery, such as liquid handlers or TPN Compounding Systems. A large user friendly work zone offers more usable space while making the farthest corners easier to reach.
