Simple Pressure and Vacuum Switch Technology Helps Collect Crucial DNA Evidence

Share Article

From cold case to criminal conviction, the cutting edge M-Vac System revolutionizes crime scene DNA collection using DesignFlex™ pressure and vacuum switch technology from World Magnetics of Traverse City, Michigan. Police, crime scene investigators (CSI) and forensic lab detectives use the M-Vac System to collect better DNA samples across multiple surface environments while saving time, resources, and helping to concentrate investigative efforts.

M-Vac System for forensic scientists collects better DNA from rough, porous & smooth surfaces. Used at crime scenes and forensic labs around the world. The M-Vac wet-vacuum collection system is monitored using the DesignFlex pressure & vacuum switches.

Used by law enforcement, CSI and forensic labs, the revolutionary M-Vac System collects better DNA from variable crime scene surfaces. The system uses pressure & vacuum switches from World Magnetics.

For many years, DNA data has played a crucial role in solving crimes. Traditionally, forensic departments have taken sample collections by using swabs. However, this has not always been the optimum solution for collecting micro-particles from rough, porous or smooth surfaces. With the introduction of the M-Vac System, this situation is changing. Developed as a wet-vacuum collection system, this revolutionary new machine enables forensic scientists to collect more DNA material both at crime scenes and in forensic labs around the world.

The M-Vac system works by delivering a sterile, DNA free solution to the sample surface to collect DNA material which is simultaneously recovered using a vacuum collection system. This solution is then concentrated and analyzed by downstream DNA processes and instrumentation to create a potential DNA profile. Due to their pressure and vacuum system requirements, M-Vac Systems contacted World Magnetics Company in Traverse City, Michigan. Using World Magnetics Company’s reliable PSF103 pressure switch on the delivery system and PSF109 vacuum switch on the collection system has enabled M-Vac System’s the ability to monitor these two simple but very crucial steps in the process. The addition of these reliable switches gives the operator the ability to make sure the system is functioning correctly. This in turn leads to better sample collections.
