Filter Cassette, DPM (Diesel Particulate Matter) w/precision jeweled impactor, w/o quartz filter, support pad, 10Pk

DPM Cassettes are not just for diesel particulate matter! Use DPM Cassettes in atmospheres where it is necessary to separate submicron particles such as DPM, carbon nanotubes (CNTs), and carbon nanofibers (CNFs) from other respirable dust. DPM Cassettes meet NIOSH Method 5040 specifications for elemental carbon analysis of DPM or NIOSH CIB65 for carbon nanotubes and carbon nanofibers. DPM Cassettes may be used with a cyclone to screen out large particles to prevent filter overload.
