FAQ

Why would I use the M-Vac instead of swabs, sponges or contact plates?
The M-Vac is able to get statistically higher collection in every step of the sampling process: discovery, extraction, and elution. Successful detection starts with a good sample.

What surfaces can be sampled with the M-vac?
The M-Vac can be used on almost any surface, including stainless steel, plastic, rough masonite, carpet, floor tiles, product surfaces, fabric, vegetable and meat surfaces, and many others. This graph shows the sampling effectiveness of the M-vac compared to sponges for four surface types.

How will the M-Vac sampling system help me detect pathogens?
The M-Vac samples a larger surface area more aggressively and without elution resulting is a liquid sample in a bottle ready for laboratory use. It can be used with whatever detection method you are already using, whether it is an in-house lab or testing service. Detection is improved when a better sample is collected.

What types of solutions are available and are they sterile?
Currently have two solutions available, both of which are sterile: Butterfields buffer and a neutralizing buffer. We can also create custom solutions to meet your sampling needs.

What is the maximum sample surface area?
The M-Vac can sample up to 10 square feet (9300 square cm) per collection bottle. The M-Vac can sample one big area or multiple smaller areas. Changing collection bottles is fast and easy.

How far away from the system can I take a sample?
Samples can be collected up to 60 feet away from the main unit (SEC).

Is the system portable?
Yes, the SEC unit comes with a wheeled cart to facilitate movement to multiple sampling locations. A more portable unit is currently in development.

Can the M-Vac be used on meat carcasses?
Yes. This graph shows recovery of E. Coli from hog and beef carcasses with the M-Vac, excision and sponge.

How does the M-Vac compare with the excision method on meat?
It is statistically similar, see this graph.

How does the M-Vac compare with the excision method on fruits and vegetables?
It is statistically similar. This graph shows M-Vac recovery of Salmonella from cantaloupe compared to excision and massage.
