Laboratory Services

Flow Sciences is a leading resource for powder and vapor Containment Equipment.  

Our primary mission is to build a strategic partnership with our clients.

 We work hand-in-hand with our clients on a journey of discovery to identify the processes, containment objectives, materials and end users’ interactions.  Using this collaborative approach, Flow Sciences can design the best containment solution that will not only protect the workers, but also   encourage good lab practices through ergonomic considerations.

Flow Sciences’ team of distributors, sales managers, project managers and engineering work with our clients to create the final design, which will determine the necessary testing protocols  to evaluate the containment effectiveness. 

Our in-house resources for manufacturing and laboratory testing ensure our client’s final product conforms to all relevant standards for containment performance and other design features.  I In addition to standard testing, FSI also offers factory acceptance testing utilizing surrogate powder with the option of utilizing our staff or yours.  This testing can be performed by FSI personnel or third party industrial hygiene partners.  We can also assist in establishing guidelines and connections for site acceptance testing once the equipment is installed at the client site.  Additional resources include training, manual supplements, and cleaning protocols.

Flow Sciences commitment does not end upon  shipment of the equipment to the client site.  It is an on-going relationship within an ever-changing industry.  Containment levels and applications will continue to present challenges and we will be here to work with you to create the solutions.



Each enclosure series is tested to relevant standards based on enclosure dimensions.
Note: Each custom unit is tested to the relevant standards based on enclosure design.

Certification Guidelines

Flow Sciences is your partner for all your containment needs.  For detailed assistance in the certification of your system, please refer to our certification guidelines.  Designed for certifiers, metrologists and other persons responsible for ensuring the enclosures are correctly configured, this document should be used in conjunction with the user manual provided with the enclosure.  For ‘standard’ style enclosures, simply refer to this style within the certification guidelines document.  For ‘custom’ enclosures, please refer to the Introduction and Description sections to identify which enclosure type should be used for certification.  The document also includes a troubleshooting guide for the more common issues.  If you still have questions, please do not hesitate to contact us.



Flow Sciences has a wide range of enclosures, designed to offer the correct containment solution to the end user. Many of the styles use the same test standards and therefore only a select series of certification techniques will be needed to certify and operate these enclosures. Additionally, almost all of the ‘custom’ units supplied by Flow Sciences are based on a standard type of enclosure. The user manual for every unit will identify the ‘series’ that the enclosure belongs to. This information can usually also be found on the serial tag.

Certification Quick Guide to Enclosure Set-Up

*Some EHA/P/G models have a maximum face velocity of 90 LFPM (0.45 m/s).


Flow Sciences is your partner for all your containment needs.  In addition to the enclosure and components necessary for startup, a custom manual for your system is provided.  Within every Flow Sciences manual, you’ll find important information, including:

  • A description of the system
  • Installation and operating instructions
  • Change out procedures
  • Troubleshooting
  • Common spare parts ordering information

Please refer to your manual for information about your containment system.  If you still have questions or need a copy of your manual, please do not hesitate to contact us.
