Microbial-Vac Systems, Inc. offers a wet-vacuum surface sampling device called the M-Vac. This tool increases DNA collection efficiency by up to 70 times versus dual swabbing. It is useful on various substrates and is especially effective when the DNA is at low/trace levels and spread over a large area. The M-Vac operates by spraying a pressurized, sterile, DNA-free solution onto a surface of interest while simultaneously applying vacuum to collect solution and entrained DNA from the surface. The vacuum pulls the solution into a collection bottle that is leak proof and easily sealed for chain of custody verification. Call today for more information or for an on-site demo.
