m-ColiBlue24 Broth, Hach 100mL
m-ColiBlue24 Broth
In 24 hours, Hach’s m-ColiBlue24® Broth provides simultaneous results for total coliforms and E. coli. This ready-to-use media eliminates the need for measuring, mixing, and autoclaving steps required for preparing dehydrated media. Available in glass ampules (26084-20), plastic ampules (260845-00), 100 mL bottles (26084-42), and agar plates (28052-15), it offers maximum shelf life and ease of use. With m-ColiBlue24 Broth, you can enumerate total coliforms and E. coli on one petri dish and easily differentiate colonies—red and blue indicate total coliforms, while blue specifies E. coli. This broth ensures optimal recovery of stressed and injured organisms.
Use Cases
m-ColiBlue24 Broth is suitable for monitoring and evaluating total coliform and E. coli in:
- Drinking water
- Wastewater
- Bottled water
- Beverages
- Surface, ground, and well water
- Ultrapure water
