M-Endo Coliform Broth Liquid Media Ampoules, 2mL, Nonsterile, 50/Pk
GVS SKU: 10496103

Featuring a ready-to-use selective and differential liquid formulation, this M-Endo Coliform Broth comes pre-dispensed in single-test 2mL plastic ampoules for the detection and enumeration of total coliform bacteria in water samples by the membrane filtration technique. Supplied 50 ampoules per pack, the broth eliminates in-house media preparation and the manipulation associated with bulk packaged media, supporting a uniform and consistent test workflow.

Key Media Characteristics

• Selective and differential formulation that distinguishes lactose fermenters from non-fermenters.
• Sodium sulfite and basic fuchsin replace bile salts to inhibit the growth of Gram-positive bacteria.
• Lactose-fermenting bacteria produce acetaldehyde that reacts with the sodium sulfite and fuchsin to form red colonies.
• Rapid fermentation of lactose generates aldehydes, producing the characteristic metallic green sheen used to identify E. coli.
• Lactose non-fermenters form colorless colonies for clear visual differentiation.

Key Construction Characteristics

• Single-test 2mL plastic ampoule format that avoids the breakage and handling of glass ampoules.
• Pre-portioned dosing reduces waste and spoilage compared to bulk media.
• Supplied 50 ampoules per pack.

The pre-measured ampoule format delivers reproducible volumes that promote consistent results across every test. Each ampoule is poured directly onto the absorbent pad of a membrane filtration setup, supporting reliable presumptive identification of coliforms and protecting sample integrity throughout water quality analysis.
