Sample Transport ☆ Culture ☆ Chromogenic Result

InTray® COLOREX™ Screen

InTray COLOREX Screen is for rapid isolation and differentiation of urinary tract pathogens. Suitable for direct plating of urine specimens. The major target of this medium is the detection of urinary tract pathogens, but COLOREX Screen has a broader application as a general nutrient agar for the isolation of various microorganisms.

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

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.
