⭐⭐⭐⭐⭐ 4.5 / 5 | Google reviews for norlab.us
The Norlab laminar flow cabinets offer the highest level of product and sample protection that your laboratory requires for handling sensitive materials and contamination-critical processes, helping maintain a clean and controlled work environment:
• Containment
Our laminar flow cabinets deliver a continuous, unidirectional stream of HEPA-filtered air across the entire work surface — shielding your samples, cultures, and materials from airborne particles and cross-contamination, in both horizontal and vertical configurations.
• Customization
Our laminar flow cabinets can be customized in width, airflow direction, worksurface material, lighting, and filtration setup to match the specific cleanroom requirements and bench layout of your laboratory.
• Compliance
Our laminar flow cabinets meet SEFA 1, ANSI/ASHRAE 110 and ISO 9001 standards, and are built in accordance with SEFA guidelines, ensuring your laboratory maintains the contamination control levels required for every audit and accreditation review.
High-quality Airflow

• SEFA 1
Performance standard developed by the scientific equipment and furniture association (SEFA) for laboratory laminar flow cabinets and ventilated enclosures. Establishes requirements for design, construction, airflow performance, containment effectiveness, structural integrity, operational safety, and long-term reliability. Provides testing and evaluation criteria to assess the ability of laminar flow cabinets to deliver uniform HEPA-filtered airflow, maintain clean working conditions, and reduce particulate contamination during sensitive laboratory procedures. Widely referenced by laboratory planners, architects, manufacturers, research institutions, pharmaceutical facilities, healthcare organizations, educational laboratories, and industrial testing environments requiring controlled clean-air workspaces.
• ANSI/ASHRAE 110
American national performance standard developed by the american society of heating, refrigerating and air-conditioning engineers (ASHRAE) for evaluating laboratory airflow systems and ventilated enclosures. Establishes testing procedures and performance criteria for airflow velocity, airflow uniformity, containment characteristics, and overall ventilation performance under laboratory operating conditions. Commonly referenced to assess airflow behavior and operational performance in laboratory environments where controlled air movement and contamination reduction are essential.
• ISO 9001
International quality management standard published by the international organization for standardization (ISO). Establishes requirements for a documented quality management system (QMS) focused on consistent manufacturing processes, quality assurance, customer satisfaction, continuous improvement, and product traceability. For laminar flow cabinets, ISO 9001 certification demonstrates that manufacturing operations follow recognized quality management practices designed to ensure consistent product quality, reliable performance, manufacturing precision, and compliance with customer and regulatory requirements across laboratory, healthcare, educational, pharmaceutical, and industrial applications.
• The airflow is incredibly consistent, and our regular validation testing always shows particle counts well within specifications. The investment has paid for itself through reduced contamination incidents and improved workflow efficiency. ⭐⭐⭐⭐⭐
• Our production line requires absolute cleanliness for semiconductor assembly. The horizontal flow cabinet from Norlab provides exactly what we need – continuous, particle-free air across our entire work surface. ⭐⭐⭐⭐⭐
Laminar flow cabinets are designed to protect the product or sample — not the operator. They are suitable for non-hazardous processes that require a particle-free environment, such as media preparation, cell culture plating, sterility testing of non-pathogenic materials, and general microbiology work involving BSL-1 organisms. However, laminar flow cabinets are not appropriate for work involving pathogens, human tissue, or hazardous chemicals — those applications require a biological safety cabinet (BSC). Norlab offers both horizontal and vertical laminar flow cabinets, and the team can help you determine which airflow orientation best suits your specific laboratory process.
No. laminar flow cabinets provide product protection only — they deliver HEPA-filtered air over the work surface to keep samples free from airborne contamination. They do not protect the operator from chemical vapors (that’s a fume hood’s function) or from biological hazards (that’s a biological safety cabinet’s function). Using laminar flow cabinets for hazardous materials puts the operator at serious risk. Norlab manufactures both laminar flow cabinets and fume hoods, and can advise on the correct equipment for your specific application.
In horizontal laminar flow cabinets, HEPA-filtered air flows from the back wall toward the operator, sweeping particles away from the work surface and out the front opening. In vertical laminar flow cabinets, filtered air flows downward from the top onto the work surface and exits through front and rear perforations. Choose horizontal when working with tall items or when you need unobstructed access from above. Choose vertical when working with multiple items on the surface (vertical airflow prevents cross-contamination between samples) or when operator splash protection is preferred. Norlab offers both configurations in 1200mm, 1500mm, and 1800mm widths.
Laminar flow cabinets should meet ISO 14644 (cleanroom classification), and the HEPA filters should be tested per IEST-RP-CC001 (filter efficiency). After installation, laminar flow cabinets must be certified annually through DOP/PAO aerosol challenge testing (to verify filter integrity) and airflow velocity measurement (to confirm uniform laminar flow). Some regulated industries (pharmaceutical, compounding) require semi-annual certification. Norlab laminar flow cabinets are manufactured and tested to meet these standards, and the team can provide documentation to support your facility’s compliance requirements.
With proper maintenance, laminar flow cabinets from Norlab have an expected operational lifespan of 15–20 years for the cabinet structure, blower motor, and frame. The components that require periodic replacement are: HEPA filters (every 3–5 years), pre-filters (every 6–12 months), UV germicidal lamps if equipped (every 8,000–10,000 hours of use), and fluorescent or LED work lights (as needed). The Phenolic work surfaces resist corrosion and chemical damage, maintaining their integrity throughout the cabinet’s service life.
