The M2 is a patent-pending two-sided sampling cassette for easier and more efficient use in the field and in the laboratory.  This is the first cassette to provide sampling options to field personnel. The M2 Cassette is also the very first of its kind for laboratory personnel. It provides one-time preparation for two samples, pre-printed traverse marks on the collection slide for standardized counting, and side-by-side comparison of the samples under the microscope. The cassette operates at an optimal flow rate of 15 liters per minute for 10 minutes, 5 minutes, or 1 minute, depending on the environment, and it can be used with commercially available wall sampling adaptors.  
Air particles are deposited onto the adhesive over a rectangular-shaped area of approximately 16 square millimeters.  The Multi-Mold Cassette is a one-of-a-kind, unique collection device, and is definitely the new generation for particle collection in the 21st century.
