InTray® COLOREX™ Listeria - Prepared Plated Culture Media for L. monocytogenes & L. innocua

COLOREX™ Listeria and COLOREX ID Listeria, traditionally used in tandem, isolate and chromogenically differentiate colonies confirming the presence of Listeria monocytogenes with prepared plated culture media. When used together, COLOREX Listeria provides initial differentiation and presumptive identification, while COLOREX ID Listeria provides confirmation of suspect L. monocytogenes colonies re-plated from COLOREX Listeria. Together they make preliminary detection and confirmation easy by producing distinct chromogenic differences with typical identifying characteristics, both macro and microscopically, within as little as 18-24 hours. Both devices inhibit the growth of mold, fungi, and other bacteria including E. coli and E. faecalis

Specifications

Product Principal
  • 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

Features and Benefits

SHELF-LIFE AND DURABILITY

  • Designed for long shelf life, durability and stackable for incubation, or 12 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

For research use only.
Some strains of L. lvanovii may also give blue colonies with white halos distinguished during identification. The species L. ivanovii is rarely found in food. Some strains of B. cereus can also grow as blue colonies. They can easily be distinguished from colonies of L. monocytogenes as they are much larger with an irregular edge to the colony and very large white halo.
