Biosafety cabinets are required to meet safety compliance regulations to protect users, samples, and the environment from potentially hazardous material. Annual maintenance helps ensure your Class II biosafety cabinet maintains optimal performance and meets compliance requirements.

Unity™ Lab Services provides testing to meet applicable U.S. and international standards. In North America, field certification is performed in accordance with NSF/ANSI 49 standards by accredited technicians. In Europe, verification of performance is provided according to EN 12469 safety standards¹.

The maintenance and testing process includes the following procedures²:

• Physical check to verify cabinet meets manufacturer’s specifications
• Testing and resetting the airflow monitoring and alarms
• Downflow velocity profile test
• Inflow velocity test and/or efficiency of front aperture
• Airflow pattern or smoke tests
• Site installation assessment
• KI-Discus test³
• Evaluation of remaining HEPA/ULPA filter life, installation, and replacement filter leak tests as needed

1. Annual testing requirements differ by country. In accordance with EN 12469 standards, testing in Europe does not constitute an accredited service certification.
2. Annual service and testing is subject to variation depending on local best practices and requirements. Elective tests such as vibration, light intensity, and noise level measurements may be available on request.
3. KI-Discus test is performed routinely only in the United Kingdom and Ireland and is optional elsewhere. For more information, please contact your local Thermo Fisher Scientific service representative.
