Allegro's Multi-Test Air Sampling Cassettes are patent-pending, two-sided sampling cassettes for easier and more efficient use in the field and in the laboratory. These are the first cassettes to provide sampling options to field personnel. Each cassette can be used to collect two different samples, two identical samples concurrently, or one sample while using the other side as a control. These M2 Cassettes are also the very first of their kind for laboratory personnel. They provide one-time preparation for two samples, pre-printed traverse marks on the collection side for standardized counting, and size-by-side comparison of the samples under the microscope.

Features:

• Features a flat rectangular side for easy labeling
• All are pre-serial numbered, bar coded with “use by” date
• Tamper evident tape eliminates chance of using a used cassette
• Silk-screened slides include labeled A/B sides and lines for
  identifying mold spurs during lab analysis
