Study reveals M-Vac’s superior results

m-vac systemStudy reveals M-Vac’s superior results. A (UC)-Davis study reveals that the M-Vac’s unique DNA collection is superior when compared to traditional methods such as swabbing and cutting.

From PRWeb: “The UC-Davis studies focused on scenarios involving large surface area requirements, recovering minute or degraded DNA material from skin, with limited knowledge of where to sample. This is common to sexual assault crimes where biological stains may not be visible.

Researchers tested the hypothesis that the M-Vac’s wet vacuum technique allows the analyst to sample larger areas and collect higher yields of suspect DNA material from a victim’s skin and clothing.” An infographic about this is here.

The M-Vac was instrumental in solving the Krystal Beslanowitch murder. In 1995, Krystal’s nude body was found lying face down on the rocks, bloody and broken, on the banks of the Provo River, Utah. She was 17 years old. Parts of the large, granite rocks were saved as evidence as well as scrapings from under Beslanowitch’s fingernails. The M-Vac gave police the answers they needed.

From the Salt Lake Tribune: “The M-Vac was invented in Utah by Jared Bradley’s father in 2002 as a way to suck bacteria off food. Then Bradley described it to his friend in the FBI, who coveted such a tool for crime scene investigation. Bradley’s Bluffdale-based company (his father died in 2009) tried it out — and discovered that it could glean 40 percent more DNA from a saliva stain on polyester than a cotton swab, and 88 percent more from a blood stain on nylon fabric.”

The M-Vac System© is a liquid based biological evidence collection system. Simply put, the wet vacuum sprays a sterile buffer while simultaneously vacuuming the liquid with any cellular material that was present from a variety of surfaces. You can see it in action here.
