InTray® COLOREX™ MRSA - Prepared Plated Culture Media for Methicillin Resistant Staphylococcus aureus

InTray® COLOREX™ MRSA prepared preplated culture media enables the growth, observation and selective isolation of Methicillin Resistant Staphylococcus aureus.


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
  • Visual chromogenic differentiation
Accurate Detection

Inhibit the growth of yeasts, mold, and fungi, resulting in 91.5% specificity for the growth of Oxacillin strains.

  • Designed for durability and stackable for incubation, or 3 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 


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


  • Time-to-result
  • Cost of laboratory materials 
  • Medical waste
