The term Laminar Flow as it applies to hoods or clean air equipment can mean many things. "Laminar Flow" typically means air flowing in one direction (unidirectional) with very low turbulence. 

Laminar Air Flow Hoods

When using a fume hood, it is important to have proper airflow, in order to avoid release of chemical vapors from the face of the hood into the worker’s breathing zone. CAT offers face velocity measurement and smoke containment visualization as a means of documenting a fume hood’s performance.

Fume Hoods


We provide these services to the wide range of industries that use this equipment for research and production activities, including:

Biological Safety Cabinets

Class III (CACI/CAI) BSC lines have been a biosafety workhorse for many decades, serving the communities requiring up to BSL-4 containment and containment for operations generating pathogenic and toxin aerosols. 

Testing Cleanrooms" would include:

  •  Airflow Velocity/Volume

  • HEPA Filter Leak Test

  • Particle Counts

  • Room Pressurization

  • Visual Airflow Characterization

  • Light Levels

  • Noise Levels

  • Temperature/Humidity

  • Volometric Air Sampling

This service is performed to support our customers contamination control efforts. Testing includes sample collection and referral to our support laboratory where incubation and identification are performed. We then provide a written report outlining details of the tests, including: sample locations, sample times, collection media used, and viable particles found through sampling. Upon request, we can provide recommendations for contamination control.

CAT provides NSF 49 approved Hydrogen Peroxide Vapor decontamination for Class II BSCs and small rooms.
