Part #: NU-543E

Features

The LabGard® ES model NU-543E Class II Biosafety Cabinet is offered as a 230-volt cabinet with a 254 mm (10-inch) access opening, TUV and NSF listings in four unique sizes. Model NU-543E offers the very best in personnel, product, and environmental protection.


Safety and Performance

Industry Listings

Model NU-543E holds TUV and NSF listings meeting standards EN 12469 and NSF/ASNI 49 for biosafety cabinetry at a 254 mm (10-inch) access opening in nominal 0.9 meters (3-foot), 1.2 meters (4-foot), 1.5 meters (5-foot), and 1.8 meters (6-foot) widths.


Dynamic Air Barrier

An air barrier at the front opening of the cabinet provides personnel protection by creating an inflow velocity of 0.53 m/s (105 fpm).


True Laminar Airflow

Uniform air is provided from the supply filter at a download rate of 0.30 m/s (60 fpm) minimizing cross contamination.


Construction

A Size that Fits Your Workflow

Model NU-543E is offered in four unique sizes to meet your application and facility space. NU-543E is offered in nominal 0.9 meter (3-foot), 1.2 meter (4-foot), 1.5 meter (5-foot), and 1.8 meter (6-foot) widths.


Monolithic Design

The process starts with a single sheet of 16/18 gauge, Type 304 stainless steel that is bent to create the exterior walls of the cabinet. Two additional sheets are seam welded into place creating the ceiling and floor of the cabinet. A smaller sheet of stainless steel is then bent and welded into place to create the interior walls of the cabinet. The result is a solid single piece shell that eliminates the user of rivets, gaskets, and sealants.

NU-543E Construction Matters
 

Coved Interior

A sheet of 16/18 gauge, Type 304 stainless steel is bent to create the interior walls of the biosafety cabinet. The corners of the work zone are coved creating an easier surface to clean and maintain.


Filter Integrity Check

Model NU-543E features large H14 99.995% @ 0.025 MPPS HEPA filters that are tested using EN 1822-1 testing standards as prescribed by biosafety cabinetry standard EN12469. Exhaust and Supply HEPA filters feature more filter media equating to longer filter life and lower operating costs. HEPA filters are tested twice during the manufacturing process. Once before the filter is installed and again fitted in the biosafety cabinet before it ships. This integrity check process ensures you receive the safest biosafety cabinet out of the box with zero headaches. We believe in our process so much we included our filters in our warranty.


Technology

Ultra High-Efficiency Motor

Not only save on your energy bills but your total cost of ownership. A single ultra-high efficiency motor features more torque than previously used technologies extending the life of your filters.


FlowGard™ Electronic Control System (ECS)

Using the same technology as your service professional uses to certify your biosafety cabinet, FlowGard™ ECS features a dual thermistor airflow sensor (Intelliflow) to monitor the cabinet’s airflow performance. The ECS also automatically compensation for filter loading and line voltage variances maintaining airflow performance resulting in consistent safety conditions.


HEPEX™ Zero Leak Airflow System

A flexible plenum produces true laminar airflow over the work zone by evenly displacing air over the supply filter. The positive plenum is maintained under negative pressure, so any potential leak will be re-directed back into the plenum and pass through the supply or exhaust filter.


High-Efficiency Particulate Air Filters

Model NU-543E features H14 HEPA filters in the supply and exhaust airflow track. H14 filters are 99.995% efficiency at most penetrating particle size.


Ergonomics

A Larger User-friendly Work Zone

A large user-friendly work zone reduces clutter allowing you to create a safer work environment allowing for proper aseptic technique minimizing potential cross contamination.


Shorter Reach into the Work Zone

The shortest reach into the safe work area in the industry, model NU-543E features a 152 mm (6-inch) reach until you reach the work zone. The short reach help reduces stress on back, neck, and arms minimizing workplace injuries.
