Sample Transport ☆ Culture ☆ Chromogenic Result

InTray® COLOREX™ Screen

Streamline your workflow with simultaneous growth, observation, and chromogenic differentiation. Now you can see selected pathogenic species frequently found in the urinary tract, including gram+ and gram— bacteria. InTray COLOREX Screen makes preliminary detection easy by producing distinctive color and morphology differences between selected pathogenic species within as little as 24 hours – all while inhibiting the growth of yeasts, mold and fungi. E. coli and Enterococcus are positively identified on the initial plate, greatly reducing the need for confirmatory testing.

COLOREX Screen can also be used to differentiate various microorganisms in other infected areas; e.g. scars, wounds, etc.

In addition, COLOREX Screen is useful when supplemented with various antibiotics in detecting increasingly important nosocomial and multidrug resistant microorganisms.

For more information regarding InTrays with antibiotic supplementals, please see COLOREX ESBL and COLOREX KPC.

Specifications
