37 mm Cassettes in Styrene

37mm air sampling cassettes are manufactured to meet standards set by NIOSH, OSHA, and EPA. Cassette housings are made from polystyrene or polypropylene, and are available in two- or three-piece configurations. They come preloaded and ready to use, and are assembled to strict quality assurance standards.

One of the main features of this cassette is its leak-free design, which helps ensure accurate and reliable sampling results. They are also suitable for use in the Hexavalent Chromium ID 215 method, which is used to measure hexavalent chromium levels in air.

The tapes were tested for gravimetric stability and found to have less than 0.5% stability after 24 hours at 48% relative humidity and 50°C (122°F). The ash content is also low, namely less than 1%, which is important for accurate analysis of collected samples.

Overall, this 25 mm air sampling cassette appears to be a high quality and reliable choice for collecting air samples in a variety of applications.

Product Details


  • The three-piece housing includes an additional ring, usually ½” long, separating the inlet from the filter media.
  • They offer increased flexibility over two-piece models because they are suitable for both open and closed surface sampling applications, and are compatible with aluminum cyclones connected to spacer rings.
  • However, as mentioned above, a larger surface area means greater electrostatic forces, so fewer contaminants enter the filter membrane.
