All Thermo Scientific™ Precis™ Detection Methods follow the principal of a single overnight enrichment, a single chromogenic agar plate and a single, simple confirmation step. Compared to traditional culture-based methods, Precis Methods are simpler to run and generate results in a reduced timeframe enabling quicker actions and shorter product hold times.

*Presumptive-positive colonies of Salmonella species, Listeria species and L. monocytogenes can be confirmed in around 15-20 minutes. Presumptive-positive Cronobacter species are confirmed in around 24 hours.

 

The Thermo Scientific Listeria Precis Enumeration Method and Thermo Scientific™ Brilliance™ chromogenic agar enumeration methods are equally simple. They replace standard methods, that require multiple dilution and plating steps, with a single dilution and single plating step, followed by simple confirmation.
