Biosafety Cabinet Certification
Regulatory Guidance / Test Methods: ​
We offer testing, certification, and maintenance of biological safety cabinets. We certify BSCs to meet NSF-49, OSHA, NIH/CDC, and manufacturer’s standards. Our reports are supplied electronically same day.
BSC tests should be conducted whenever units are installed, moved, or following any significant maintenance. NSF 49 recommends that certifications be done annually, with more frequent certifications (semi-annual) performed for BSCs in cGMP environments. Biosafety cabinet testing and certification is critical to ensuring product and patient safety.
Primary Services
Inflow Velocity Measurements
Ensures proper inflow is maintained for operator protection and environmental protection.
Downflow Velocity Measurements
Documents the air in the work area is unidirectional and functioning as designed, preventing cross contamination, and providing product protection from the environment.
Hepa Filter Integrity Testing
Documents leakage or defects and ensures HEPA filters provide required filtration to prevent both product and environmental contamination.
Airflow Visualization/Smoke Study
Qualitatively verifies airflow directions using a small source of visible fog.
Site Installation & Alarm Calibration
Confirms alarm performance and assesses installation of units for NSF and OSHA compliance.
Additional Services
Non Viable Particle Counting
Performed in accordance with ISO 14644-1 or EC Annex 1, and provides a quantitative evaluation of air quality in terms of particulate in the work area.
Sound Testing
Verifies hood operation/usage will not contribute to worker fatigue/stress and may be performed in association with troubleshooting.
Vibration Testing
Ensures product is not subject to damage due to vibration and may be performed in association with troubleshooting.
Light-Level Testing
Ensures fluorescent lighting levels are sufficient to prevent operator fatigue.
