InTray® COLOREX ECC - Prepared Plated Culture Media

COLOREX™ ECC enables simultaneous growth, observation and chromogenic differentiation of E. coli and other coliforms in food or water samples. Water contamination due to fecal coliforms consists mainly of E. coli and thermotolerant Klebsiella. The fully enclosed InTray system enhances safety by preventing contamination and reduces exposure to collected samples. 


Product Principle
  • Combine collection, culture, result and microscopic observation in one IVD device.  
  • Highly selective prepared media in a device designed for in-vitro specimen transport 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
  • The 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
  • Selectively produces distinctive colony growth with typical identifiable morphology

Features and Benefits

Shelf-life and durability

  • Designed for long shelf life, durability and stackable for incubation, or 6 month storage. 
  • No re-plate or wet mount 
  • Once InTray is 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 

Key Features

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

You'll immediately experience a reduction in:

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