Interscience Scan®4000 Automatic Colony Counter

Scan®4000 is an automatic colony counter from Interscience, equipped with a 5 megapixel HD CCD camera and Japanese optics. Designed for microbiology laboratories seeking to eliminate the slowness and error-prone nature of manual colony enumeration.

The instrument features a 7-combination automatic white LED Dome illumination system that delivers high-contrast imaging across various Petri plate formats (Ø 55-150 mm round and 120 mm square). It can enumerate up to 1,000 colonies per second and detect colonies as small as 0.05 mm. Automated cluster separation, polygonal exclusion zones, and manual correction capabilities enhance result accuracy.

The instrument automatically enumerates chromogenic media, 3M PetriFilm, MC-Media Pads, and Compact Dry ready-to-use culture media. Data transfer via USB and LIMS connectivity is supported with 21 CFR Part 11 compliant traceability systems. Results are recorded with image, sample number, and date/time information, and can be exported in PDF, Excel, and jpg formats.
