Filters and Cassettes

SKC has a wide range of high quality materials for filters and remains on the leading edge of particulate air sampling through active research and collaboration with leading experts around the globe for sampling media. We can offer Membrane Filters, Depth Filters, Coated (Treated) Filters and Cassettes, as well as a range of filter and cassette accessories.

Filters and Cassettes

A typical filter has a rough side and a shiny side. The shiny side is easier to read under a microscope. Therefore, expose the shiny side to the air when collecting samples for microscopic analysis. The rough side holds the dust more effectively, so the rough side is exposed for gravimetric sampling.

See our Filters and Cassettes Selection Guide for more advice.
