This 37mm, MCE cassette is .8µm mixed cellulose ester and is specifically designed for lead sampling. 50 per box.

The M2 is a patented, 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. Each cassette can be used to:

• Collect two different samples
• Collect two identical samples concurrently
• Collect one sample while using the other side as the control

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 side for standardized counting, and side-by-side comparison of samples under the microscope.
