InTray® COLOREX™ SalmonellaBiomed InTray Colorex Salmonella culture media for Salmonella diagnostics

InTray® COLOREX™ Salmonella

Colorex™ Salmonella  allows for simultaneous growth, detection and chromogenic differentiation of Salmonella pathogens, including S. typhi and S. paratyphi, traditionally taken from clinical stool specimens. Additionally, Colorex Salmonella inhibits the growth of yeasts, mold and fungi – resulting in 100% sensitivity and 89% specificity for Salmonella compared to 78% with traditional Hektoen Agar.


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

Provides 89% specificity for Salmonella

Test Strain ATCC # Colony Appearance
S. enteriditis 13076 Mauve
S. typhimurium 14028 Mauve
E. coli 25922 Small | Metallic Blue
C. freudii 8089 Small | Metallic Blue
S. aureus 25923 Inhibited

Time to Result

24 - 48 hours, incubate at 37ºC

  • Extended 6 months shelf life (2-8°C) from the date of manufacture
  • Can tolerate extended periods at controlled room temp (≤ 25˚C), with no loss in performance.
  • Skin
  • Sputum
  • Urine
  • Genito-urethral swabs


For research use only.

For in vitro diagnostic use. Some Pseudomonas may have similar mauve colony aspect and can be eliminated by an oxidase test. Many S. typhi can be detected after 24-48h incubation as mauve variable size colonies. Final identification must be done by biochemistry and serology.

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
