The CERTUS System Brings Pathogen Detection In-house and
Puts You in Control

Using a Surfaced Enhanced Raman Spectroscopy detection method, the CERTUS System continuously monitors and identifies growing pathogenic bacteria within a fully bio-contained system.

Adding the Pre-Measured Growth Medium

It all begins with the patented Bio-Lock™ tube. Embedded in the bottom of each detection tube are pathogen-specific dry-down particles. When combined with the pre-measured growth medium, antibodies conjugate to magnetic and SERS particles.

Adding the Pre-Measured Growth Medium

Once a sample is collected, sealed in the Bio-Lock Detection tube and inserted into the Detection Unit, enrichment and detection begin immediately. The Detection Unit features a thermal chamber optimized for the selected pathogen.

Adding the Pre-Measured Growth Medium

Occurring at regular intervals, a magnet within the Detection Unit is deployed, pulling the particles into pellets. The pellets are then interrogated by a laser.

Adding the Pre-Measured Growth Medium

The Raman Spectra elicited by the pellets is read, logged and applied to a logarithm that monitors bacterial presence and growth versus time. A specified inflection point in the algorithm triggers an alert, which can occur at any time throughout enrichment.
