We provide comprehensive laminar flow hood certification services that meet CETA or USP 797 standards using NIST traceable calibrated instruments — giving you the confidence that your critical equipment is compliant, documented, and audit-ready.

Our certified technicians understand the stakes: failed audits, compromised sterile compounding, regulatory findings, and operational disruptions. That’s why we provide thorough testing with detailed documentation that satisfies your specific regulatory requirements. Whether you’re maintaining a laminar flow hood in a hospital pharmacy, a research laboratory, or a pharmaceutical setting, we ensure your equipment performs exactly as it should.

With nationwide service and rapid response capabilities, Allometrics has certified thousands of laminar flow hoods across healthcare, pharmaceutical, research, and industrial facilities. As an A2LA ISO 17025 accredited laboratory, we hold ourselves to the highest standards of technical competence and quality. We don’t just test equipment—we are your controlled environment maintenance partner protecting your products, your processes, and your regulatory standing.

Our Laminar Flow Hood Certification Process

What is Laminar Flow Hood Certification?

Laminar flow hood certification verifies that your equipment maintains proper airflow patterns, HEPA filter integrity, and environmental conditions through thorough testing. Laminar flow hoods, also known as unidirectional clean air devices (UCADs) or clean benches, provide HEPA filtered airflow within the work area to ensure uniform direction and velocity across the designated space. Our technicians measure air velocity, test filter performance, count airborne particles, and document that your equipment performs within required parameters, providing the documented proof of contamination control your operations demand.

Benefits of Regular Certification

Maintain regulatory compliance and avoid costly audit findings
Protect products and processes from contamination-related failures
Extend equipment lifespan through early detection of performance issues
Gain documentation confidence with audit-ready certificates
Prevent operational disruptions from unexpected equipment failures

Risks of Neglecting Certification

Failed audits leading to regulatory action, production holds, or facility closures
Compromised sterility resulting in contaminated preparations, invalid results, or product recalls
Increased costs when minor issues become major equipment failures requiring emergency service
Liability exposure when inadequate contamination control negatively affects product quality or patient safety
Loss of accreditation potentially ceasing operations until compliance is restored

Proactive certification protects your operations, compliance standing, and reputation.

Laminar Flow Hood Certification Services

We provide testing, certification, and repair services for horizontal and vertical laminar flow hoods or an Integrated Vertical Laminar Flow Zone (IVLFZ) from most manufacturers, including LabConco, NuAire, and GermFree.

Our comprehensive certification services include:

Air Velocity Profiling – Ensures consistent airflow across the work surface
HEPA Filter Integrity Testing – Detects filter penetration and leaks
Induction Leak Testing/Backstreaming Testing – Identifies contamination pathways
Non-Viable Particle Counting – Measures airborne particulate levels
Microbial Air Testing – Quantifies viable microorganisms in the air
Microbial Surface Testing – Assesses contamination on work surfaces
Smoke Pattern Testing – Visualizes airflow patterns and turbulence

Each certification includes detailed documentation with measurement data, pass/fail criteria, and corrective action recommendations when needed. Our testing protocols meet manufacturer specifications and CETA standards, providing you with audit-ready reports that demonstrate compliance and equipment performance. [1]

Additional testing services, like lighting measurement and sound level measurement and testing are available on request. Call our lab experts with any questions at (281) 474-3329.

Common Questions About Laminar Flow Hood Certification and Compliance

What’s involved in the laminar flow hood certification process?

Our certification process includes comprehensive testing to verify your hood maintains proper contamination control. Tests we perform include air velocity profiling to ensure consistent airflow across your work surface, HEPA filter integrity testing to detect any filter penetration or leaks, and particle counting to measure airborne contamination levels. We can also conduct smoke pattern testing to visualize airflow patterns, lighting measurements, and sound level testing when required. Each certification includes detailed documentation with all measurement data, pass/fail criteria, and any corrective action recommendations. The entire process is designed to confirm your equipment performs within required parameters and provides you with audit-ready documentation.

What does NSF 49 standard cover for laminar flow equipment?

NSF 49 specifically applies to Class II Biosafety Cabinets, not standard laminar flow hoods, though biosafety cabinets do use laminar flow technology. [3] This standard establishes performance requirements and testing protocols for biological containment equipment. Our certification services follow appropriate standards for your specific equipment type—whether you’re operating biosafety cabinets or laminar flow hoods—ensuring compliance with the specifications required by regulatory bodies and accreditation organizations.
