Instant, Reliable Detection of Biofilm Using the Bactiscan


The Bactiscan by EIT International is the leading detection system to instantaneously identify clusters or biofilm of bacteria such as Listeria on a surface. Independently validated by CampdenBRI (Assessment of Bactiscan instrument for detection of food industry biofilms – November 2020) and proven to be effective through continuous use by some of the world’s largest food production, dairy, brewing and pharmaceutical companies.

How Does it Work?
Many bacteria are protected by a thin, hard outer shell called an S-layer, or surface layer. All S-layers are part of the bacteria cell envelope and are made up of a two-dimensional array of proteins that have a crystalline appearance. It is this protein shell that is detected by the Bactiscan through high calibration LED wavelengths that work on the fringes of the Ultra-Violet spectrum. These 4 separate wavelengths, once merged will bounce off the protein crystal and emit an unmistakable green glow, often describes as a green hue.

The high intensity UV radiations emitted enables the operator to view large areas in an instantaneous and non-destructive way. Contaminants are often undetectable using other methods such as white light and UV lamps. With the handheld Bactiscan you can light up the entire surface and get an immediate result, so within seconds you can pick things up that would take hours with any other method.

Compared to ATP based systems, the Bactiscan is able to examine a much larger surface area and will reveal the presence of both alive and dead cells without needing any additional chemicals or reagents.
