Synbiosis Colony Counter Protos 3

Colony Counter and Chromogenic Identification System, without PC, automated, 1.4 MP CCD camera


Protos 3 is an ergonomically designed imaging unit with dark screens to eliminate ambient light effects and improve imaging results. The unit contains a high resolution camera with red, blue and green LED lighting (patent pending) and software with validation plate. The software features a single user level with on screen commands, allowing users to intuitively set their system up in minutes. These settings can be saved to make analysing the same plate types at a later date, a quick one touch process. Comes as standard for Count, Spiral and Dilution series counting and Chromogenic identification. No other options available and no LIMS connectivity

Protos 3 is a revolutionary automated colony counter and chromogenic identification system. Using its sensitive CCD camera and unique lighting coupled with powerful analysis software, Protos 3 counts colonies in seconds and automatically identifies microbial species by their colour on chromogenic plates. This provides accurate, objective and fully traceable results.

The compact Protos 3 attaches via USB to a computer, where microbiologists can input their plate identification and with the one-click colony counting and chromogenic ID software can rapidly analyse a wide range of plate types. The count results can be automatically transferred to Excel where the count, plate ID and images can be saved. This GLP compliant process, with its full audit trail eliminates transcription errors to provide accurate, objective data, which can be reviewed at any time and used to produce professional reports.

Protos 3 can be used with both small and large plates (up to 150mm) to read a range of format types including spiral, pour, spread and dilution series plates. The system’s camera is so sensitive it can routinely detect colonies as small as 43 microns and the unique LED lighting system and Protos 3 software allows analysis of an infinite number of colonies on one plate in seconds, making this an ideal system for use in busy food and environmental microbiology laboratories.

Protos 3 is suitable for:

  • One click, automated colony counting
  • Medium throughput analysis of 75 plates in 5 minutes
  • Food and environmental microbiology labs
  • Multiple colony counting and microbial identification functions
  • Reproducible results
  • True colour recognition using unique three colour lighting
  • Classifying colonies by size, colour and shape
  • GLP compliance and full traceability
