Protos 3


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. 

Fully traceable results

  • Can input plate identification using 1D or 2D barcode
  • Automatic capability to transfer and print results and images
  • Saves counts to Excel to eliminate keying errors
  • Saves images in TIFF, Excel and  report formats
  • Archives results in accessible SQL database

Increases throughput

  • Accurately detects colonies as small as 0.043 mm
  • Precisely counts an infinite number of individual colonies in seconds
  • Analyses 75 plates in 5 minutes

Excellent detection performance

  • True colour recognition using unique 3 colour lighting
  • Identifies multiple different colony colours on one plate
  • Analyses all plate colours with a choice of light and dark backgrounds
  • Classifies by size, colour and shape
  • Objectively identifies species by colour on CHROMagar™

Reproducible results

  • Provides objective colour results
  • Eliminates keying errors with direct results transfer
  • Automatically identifies species on chromogenic plates

Simple to use

  • Intuitive software
  • Corrects for agar defects, touching colonies or sample debris
  • Marks colonies with symbols to show each counted 
  • Easy to exclude areas from a count
  • Adjustable counting area

Multiple plate reading functions

  • Pour plates
