Biological Safety Cabinets, Fume Hoods & Flow Hood Testing

Routine performance testing and certification for your laboratory hoods and biosafety cabinets ensure a safe, sterile environment that protects both your team and your critical research materials.


Ensuring laboratory safety compliance

Comprehensive Testing and Certification for Fume and Flow Hoods

Fume Hood Testing

Fume Hood Testing is an important on-going process primarily in the Life Sciences Industry that verifies a laboratory fume hood’s ability to safely contain hazardous fumes through routine performance evaluations, including face velocity measurements (typically 95-130 FPM), airflow pattern visualization (using smoke or other visible vapor), and containment tests (like tracer gas or smoke challenges, ensuring compliance with standards like ANSI Z9.5 and ASHRAE 110 for user safety.

Tests are performed by trained professionals following established standards. Results are recorded on labels affixed to the specific hoods each test period indicating testing company, technician, date of test and its operational status (Pass/Fail). Fume Hoods are certified upon installation, at least annually, or every 3-6 months dependent upon high or low risk use.

Laminar Flow Hood Testing

Laminar Flow Hoods or Clean Benches are used in a wide variety of industries. These benches are used as critical environments to protect “products in process” from contamination. Laminar Flow Hoods are certified upon installation and typically at 6-month intervals thereafter.

Depending on Client requirements, typical Laminar Flow Hood Testing & Certification include Air Velocity Profiling, HEPA Filter Leak or Integrity Testing, Non-Viable Particle Counting, Lighting measurement, Sound Level Measurement dBA, and Induction or Back Streaming Testing.

Tests are performed by trained professionals following established standards. Results are recorded on labels affixed to the specific hoods each test period indicating testing company, technician, date of test and its operational status (Pass/Fail).

Protecting personnel and research

Biosafety Cabinet and Glovebox Testing

Primarily used in Life Sciences applications, a Biosafety Cabinet (BSC) is a ventilated enclosure that protects lab workers, the environment, and research materials from biohazardous compounds by using HEPA filters and controlled airflow, creating a sterile workspace for handling a variety of sensitive materials. Gloveboxes vary widely and are generally used to process highly hazardous materials that otherwise cannot be processed in a normal manufacturing environment due to personnel and environmental safety concerns.

Types of Biosafety Cabinetry:

  • Class I: Protects personnel and the environment, but not the product.
  • Class II (most common): Protects personnel, environment, and product; widely used in research & manufacturing including pharmaceutical compounding (types: A1, A2, B1 and B2)
  • Glass III (Glove Boxes): Provides the highest level of containment, with completely sealed systems for highly hazardous materials.

FAQs

Have questions? We can help!

Here are some answers to common questions about this service. Still have questions? Get in touch and let’s talk through them together.

We recommend performing filter bench testing upon receipt of new filters and prior to installation to document initial integrity and performance.

Testing filters before installation helps identify manufacturing or shipping damage early and provides documentation to support responsibility if issues arise later.

Yes. If filter damage, leaks, or performance issues are identified, OSE can support repair or replacement to restore proper operation.

After repair or replacement, equipment is tested under controlled conditions to confirm restored performance and integrity before returning to service.

Yes. OSE provides documented test results, asset labeling, and field reports to support compliance and maintenance tracking.
