m Endo Broth Ampoules are ready-to-use, pre-measured liquid media designed for the selective detection and enumeration of coliform bacteria in water, environmental, and food testing applications.
Each 2 mL ampoule contains m-Endo Broth, a classic medium formulation used in membrane filtration techniques to identify Escherichia coli and other coliforms by their characteristic red colonies with metallic sheen.

This sterile, pre-filled format minimizes handling errors, reduces preparation time, and ensures consistent test performance. Ideal for laboratories performing routine water quality monitoring and sanitation verification in compliance with EPA and Standard Methods.

Features and Benefits:
• Ready-to-use 2 mL ampoules — eliminate the need for media preparation
• Selective formulation for coliform detection via membrane filtration
• Reduces risk of contamination and variability between tests
• Suitable for use with standard 47mm membrane filters
• Supports EPA and Standard Methods for water and environmental microbiology
• Compact packaging for efficient lab storage
