Air Sampling Cassettes

Professionals in a range of industries use Zefon International air sampling filter cassettes to quickly and safely collect samples of a wide range of hazardous substances, including:

  • Respirable Dust
  • Airborne Particulates
  • Airborne Metals
  • Mold Spores
  • Allergens (Pollen, Skin Cells, Insect Parts)
  • Asbestos Fibers

And more. Our products offer several benefits over competing air samplers — namely proven defect-free reliability, superior portability, and excellent overall value. Use them in any situation where the potential for an airborne particulate problem may exist. Some of the most common applications for our products include industrial workplaces, hospital and healthcare settings, and IAQ investigations.

Product Highlights

Zefon International has a long history of manufacturing innovative cassette air sampling media and related products. Our catalog is continually growing as we bring new sampling tools to market. Some of our bestselling items in this vertical include:

  • Air-O-Cell® bioaerosol cassettes: Air-O-Cell® cassettes are disposable, easy-to-use air samplers for particulate collection. Air-O-Cell® cassettes work with most standard sampling pumps, including the Zefon Bio-Pump® Plus. With them, you can collect samples without preparing slides or worrying about contamination. They feature a special adhesive that reduces the risk of sample loss due to vibration during handling and prevents blurring and washing off during staining.
  • Filter cassettes: We sell a wide range of preloaded filter cassettes that meet NIOSH, OSHA and EPA standards. Our products come fully assembled and ready for use and are made with high-quality polystyrene or polypropylene, in two-piece or three-piece configurations. Options include sterile models for fluid contamination sampling, ultra-pure PTFE models for pharmaceutical compound sampling, and models preloaded with Solu-Sert™ or Gravi-Sert™ capsules.
  • Solu-Sert™ soluble filter capsules: Solu-Sert™ soluble filter capsules consist of an MCE filter membrane sealed to a cellulose shell. We designed them to work seamlessly with our two-piece filter cassettes. Just insert the capsule into the unit to collect samples for NIOSH-approved testing for aluminum, arsenic, barium and other contaminants.
  • Gravi-Sert™ filter capsules: Gravi-Sert™ filter capsules are self-contained capsules designed to capture particulates collected by a filter cassette. They feature a PVC membrane sealed to a static-dissipative PVC shell. Applications include NIOSH testing for carbon black, total dust and respirable dust levels.
  • Inhalable samplers: Zefon International is the only manufacturer that offers a disposable inhalable sampler that complies with ACGIH, NIOSH, British Method MDHS, and ISO/CEN standards. Our inhalable samplers are small, lightweight and reliable, and designed to measure the worker’s exposure to inhalable particulates, dust and bioaerosols. We also offer a reusable version.
  • Nanoparticle (NRD) samplers: Our NRD samplers size-selectively collect nanoparticles likely to be deposited into the respiratory tract. They are lightweight and designed to be worn for personal exposure monitoring, along with a standard 25mm aluminum cyclone. After collection, chemical testing can avoid the need for more expensive electron microscope analysis.
