Why M-Vac

FBI Research

The FBI compared the M-Vac® wet-vacuum-based collection method to a wet-swabbing method on a variety of surfaces.  In July 2020, they published some of their research.  Twenty-two substrates, 2 non-porous and 20 porous, were evaluated including household items, construction materials and automotive items.  The full article along with graphs of the data and details regarding the research and findings can be found at the link below.
