Millipore's 37 mm Aerosol analysis monitors are transparent, disposable, plastic filter holders pre-assembled with Type MF (mixed cellulose esters) Millipore filters. A thin cellulose support seals the filter between monitor sections to distribute sample flow evenly over the filter surface. The three-part design holds the filter in-place when the top section is removed for open aerosol sampling.

• Pre-assembled with filters in-place
• Available with matched-weight membranes

The Average Background particle Count (ABC) value is marked on each monitor package.

Applications:
Aerosol analysis monitors are available with 0,45 µm and 0,8 µm cellulose esters membranes. Matched weight monitors contain two filters matched in weight to within 0,1 mg, eliminating test filter pre-weighing in gravimetric analysis.
