Plate reader electronically reads, interprets pathogens
3M Food Safety, St. Paul, Minn., developed 3M Petrifilm Plate Reader, a peripheral device that serves as an automated alternative to manually counting and documenting colonies of bacteria on3M Petrifilm Plates indicator tests.
The new 3M Petrifilm Plate Reader software version 4.0 automates the imaging, interpretation and data mapping of the 3M Petrifilm Rapid Aerobic Count Plate.
After individual 3M Petrifilm Plates are inoculated and incubated, they can be easily loaded into the 3M Petrifilm Plate Reader, where they are electronically read and interpreted in about four seconds. The 3M Petrifilm Plate Reader also automates logging of 128 symbology barcode labels, and allows details related to the technician, food type, food lot and dilution schemes to be electronically stored rather than transcribed by hand. Data can also be easily exported to laboratory information management systems and other reporting tools.
