Description

The LabGard (Energy Saver) AIR Limited model NU-545 is an NSF/ANSI 49 certified Class II, Type A2 biological safety cabinet delivering the long-lasting, high-quality performance you and your staff demand to protect you and your work.

Safety

Automatic Airflow Compensation

To maintain safe airflows, the LabGard Limited Edition automatically compensates for both filter loading and line voltage variance to provide you safe, constant airflow protection.

HEPEX Zero Leak Airflow System

The HEPEX™ Zero Leak Airflow System provides quiet, uniform velocities throughout the entire sterile work zone. All positive pressure chambers and ducts are surrounded by a vacuum or negative air pressure relative to the room. This feature eliminates the possibility of cabinet and gasket leaks. Uneven particulate loading is prevented by maintaining high-static pressure over the entire filter surface assuring True Laminar Airflow.

Dynamic Air Barrier

Air exchanges within a Class II, Type A2 Biological Safety Cabinet, can occur 25 times per minute. This rapid air exchange system combined with an aerodynamic, ergonomic air foil and a significantly larger access opening creates the strongest air barrier, personnel protection, of any Biological Safety Cabinet.

True Laminar Airflow

Unidirectional Airflow moving along parallel flow lines at a constant velocity minimizes air turbulence within the work zone. With proper techniques, activities within the work area can be performed safely minimizing the chance of cross-contamination.

Technology

TouchLink 2.0 Electronic Control System

TouchLink™ is an easy-to-use touch screen LCD which will operate and display all system functions. On / off functions for fluorescent and germicidal ultraviolet lights, blower motor, and interior outlets. Monitors high / low limits for down flow, inflow, and sliding window position. The password protected TouchLink ™ also contains a unique date/clock display and timer functions that can be used as a laboratory timer, purge timer, outlet timer, UV light timer, auto-run timer, night setback, or weekend turn-off. TOUCHLINK™ also contains diagnostic functions for a NSF trained service technician or certifier.

Real Time Airflow Monitoring

Using the same technology as your NSF Accredited Certifier, model NU-545 features digital dual thermistor airflow sensors in the down flow and exhaust flow air to monitor and control real-time airflow ensuring safe airflows based on air velocity instead of pressure inside the plenum.

Auto Decontamination

The automatic decontamination works in conjunction with hydrogen peroxide, chlorine dioxide, and paraformaldehyde systems. The process simultaneously runs the cabinet blower at a low rate during the decontamination cycle. This will aid in the process of distributing the decontaminant gas/vapor throughout the cabinet during the entire decontamination cycle. Window clamps securely create an air tight seal against an inner window gasket. The inlet port is connected to a connection point on top of the BSC. The outlet port is attached to a fitting on an auto decontamination exhaust seal plate.

Lower Total Cost of Ownership

Ultra-High Efficiency Motor

A single DC ECM motor with an optimally sized fan saves you up to 47% off your electricity bill compared to previously used motor technologies.

LED Lighting

Exterior LED lighting provides life up to 50,000 hours and is 30% more efficient than standard fluorescent lightning. The LED lighting provides cool white illumination of the work zone from 90 – 120 foot-candles (968 – 1291 lux).

Larger, Longer Lasting Filters

NuAire offers filters that use more filter media and offer more pleats per square inch. Combined with an ultra-high efficiency motor with more torque, a NuAire BSC can extend the life of a HEPA filter up to 10 years or more.

Night Setback

As a standard option, upon window closure, the NU-545 may allow the motor to continue to run at a lower rate to continually HEPA filter the work zone. The LED light will be disabled. If the sliding window is then opened, the cabinet will resume normal airflow set points in run mode. Night setback will save your facility money if your standard operating procedures require you to run the BSC 24/7.

Design

Monolithic Design

At the core of any NuAire Biosafety Cabinet is the single piece stainless steel shell. The process starts by bending a single piece of heavy duty stainless steel to create the back and side walls of the cabinet. Additional stainless steel sheets are seam welded into place to create the top and bottom. A smaller sheet of stainless steel is bent and welded into place to create the coved interior work zone. The final step welds the frame work into place to house the motor/blower assembly and HEPA filters. The result is a monolithic shell eliminating the need for rivets, gaskets, and sealants extending product life and enhancing safety.

Vibration Control

The motor/blower system is suspended inside the BSC using the attenumont system, a shock absorbing technology minimizing vibration transfer from the motor to the cabinet. The HEPEX Zero Leak Airflow System uses an impermeable, antimicrobial, and flameproof flexible fabric to make up the BSC’s plenum eliminating vibration transfer from the motor/blower to the plenum.

Clean-ability

The interior of the BSC features smooth coved corners for easy clean-ability. A spill trough with drain valve is located under the work surface to catch any unwanted spills. The work surface comes optionally with a prop-up work tray to easily clean under the work surface.

The need for field certification of biosafety cabinets

Biosafety cabinets (BSCs) are the primary engineering control devices used to mitigate exposure risk to biohazardous materials, particulates, and aerosols in many different industries. NuAire explains how Class II BSCs are performance tested, validated and certified by NSF International. Discover why it is vital that BSCs are properly certified in your lab, what a BSC field certification should look like, and how to find the right qualified BSC field certifier for your lab needs.

Safely disposing of a biosafety cabinet

Biosafety cabinets (BSCs) are critically important primary containment devices used to protect individuals from exposure to biohazardous materials while they are working in the laboratory. They are also large devices that often contain biologically contaminated internal parts after they have been used. At the end of their lifespan, it is therefore vital to safely and fully dispose of the BSC. NuAire explains how to conduct a risk assessment to determine what steps are needed to safely handle the retired BSC, and the disassembly guidelines set out by the NSF/ANSI Standard 49 Informative Annex 1.

Facility and Engineering Controls Using USP 800 Guidelines

Like many layers of an onion, there are unanswered questions on the intricate details of USP 800-related engineering control parameters. In addition, the multitude and flexibility of theengineering controls can seem daunting to the independent pharmacy owner. Even more concerning, and certainly at the forefront of all of the independent pharmacy owners’ minds, is the cost associated with being compliant with USP 800. The costs associated with building a new facility or remodeling an existing space, are proving to be as equally subjective as the choice of engineering controls. The focus of this white paper is to discuss the details for consideration of a good working design of a USP 800 compliant compounding lab.
