Overview

The NU-543 carries the LabGard® value proposition across the boundaries of geography and scientific applications by offering the broadest choice of configurations for environmental protection. This model features a dual thermistor airflow sensor and alphanumeric display for laboratories requiring a clear measurement of their cabinet's performance and a choice of three NSF listed work access openings for procedures needing ergonomic access to the work zone, creating the optimal BSC experience for laboratory workers.

The NU-543 Biological Safety Cabinet can optionally be made with a smooth interior for procedures such as pharmacy compounding and always includes a prop up work tray to ease regular cleaning under the work surface to prevent contamination. Double exhaust filters can be fitted to meet the requirements of an application or national guidelines regarding air standards.

A truly global product, models are available that meet NSF/ANSI 49 and EN 12469, feature multilingual displays, and can ship from multiple locations around the world. Some options and configurations are only available from North America. Consult NuAire for details.

FlowGard Control System Calculates Inflow and Downflow Velocities

The FlowGard™ Electronic Control System on the NU-543 continuously calculates and displays real-time inflow velocity using data from the exhaust airflow sensor. With clear alphanumeric readouts, intuitive membrane buttons, and support for six world languages, researchers can effortlessly navigate user and service menus. This advanced system enhances safety and efficiency, ensuring accurate airflow monitoring for optimal containment while simplifying operation and maintenance. Experience precision control, seamless usability, and enhanced lab safety—all at your fingertips.

Choice of 3 Access Openings on the NU-543 Class II Biosafety Cabinets

The NU-543 Class II Biosafety Cabinet offers a choice of 8-inch, 10-inch, and 12-inch (203mm, 254mm, and 305mm) NSF-approved access openings, allowing researchers to optimize their workflow while ensuring certified containment and environmental protection.

  • 8-inch Opening: Ideal for high-containment applications, minimizing air movement, reducing noise, and lowering contamination risk with restricted arm movement.
  • 10-inch Opening: The best balance of ergonomics and protection, offering comfortable access while maintaining strong containment.
  • 12-inch Opening: Maximizes ergonomic comfort by allowing greater range of motion for demanding procedures, making extended work sessions more comfortable.

Choose the opening that best fits your research needs, without compromising safety or efficiency.

Smooth Interior Option For The NU-543 Biological Safety Cabinet

The NU-543's smooth interior option is designed to meet the highest cleanability standards required for sterile drug compounding. By removing work zone outlets and service valves, this configuration creates an uninterrupted stainless steel surface, making routine wipe-downs faster and more effective.

Benefits for drug compounding applications:

  • Enhanced Sterility: Seamless stainless steel walls reduce contamination risks and ensure compliance with USP <797> and <800> guidelines.
  • Reduced Contaminant Accumulation: Fewer crevices mean fewer places for microbial or particulate contaminants to collect.
  • Simplified Decontamination: A smooth, continuous surface allows for quick and thorough disinfecting between batches.

For compounding environments where sterility and ease of cleaning are critical, the smooth interior option provides the ultimate contamination control solution.
