For over 50 years, Allometrics has been the trusted partner for laboratories, pharmacies, hospitals, and research facilities that depend on properly functioning laminar flow hoods. 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.
