Chromogenic differentiated result, in your clinic.

COLOREX KPC is a selective and differential chromogenic medium containing a carbapenem selective agent intended for use in obtaining a pure culture of gram-negative bacteria expressing reduced susceptibility to carbapenem-class antibiotics. The test can be performed with samples composed of mixed populations of bacteria, e.g., stool, biological fluids, surface streaks, etc. 


Product Principle
  • Combine collection, culture, result and microscopic observation in one device.  
  • Highly selective prepared media in a device designed for in-vitro specimen collection and incubation.
  • Rapid presumptive-positive diagnosis without re-plating.  InTray can be placed directly on microscope stage
  • Fully enclosed cassette with Tyvek® air filtration prevents contamination and exposure, post-collection.   
Simple Convenience
  • InTray is designed for specimen collection / inoculation at point-of-care
  • Saves time, material cost and waste, reducing exposure to collected sample
  • Place directly on the microscope tray for observation through the cassette’s clear anti-fog window
  • Visual chromogenic differentiation
Accurate Detection

Specially formulated medium promotes growth and chromogenic differentiation

  • Once inoculated, no other culture preparation is required... saving time and cost. 
  • Designed for specimen collection/inoculation at point-of-care, a fully enclosed system for transport, incubation, result and microscopic observation. 
  • The sealed prepared media device is selectively formulated for accurate detection and identification of pathogens and non-pathogens
  • Visual chromogenic differentiation and/or selective production of distinctive colony growth with typical identifiable morphology 


  • Fully enclosed cassette with air filtration system
  • Nutritive culture colony growth medium, formulated for selectivity and specificity 
  • Anaerobic or aerobic system available (on select products)


  • Time-to-result
  • Cost of laboratory materials 
  • Medical waste
  • Risk of exposure or contamination
