Compact Dry CFR | Coliform - Rapid

Compact Dry CFR plates provide rapid, reliable detection and enumeration of coliforms. A chromogenic enzyme substrate causes coliform colonies to appear blue to blue-green, making results easy to interpret, while non-coliform organisms that may grow typically remain white and are not counted as coliforms. Compact Dry CFR is especially well suited for dairy products and environmental surface testing.

Monitor coliform contamination quickly to support sanitation verification, food safety, and quality assurance programs at critical control points.

Key Benefits

• Rapid results – detect presumptive positive coliforms in as little as 6 hours, with countable results after 16–18 hours of incubation at 35 ± 1 °C.
• Simple “open–inoculate–incubate” workflow – pipette 1 mL of diluted sample directly onto the self-diffusing plate; the dehydrated medium rehydrates into a gel within seconds.
• Clear colony interpretation – coliforms form blue/blue-green colonies for straightforward counting; blue/white fluorescence under 365 nm UV light can support presumptive detection during early incubation.
• Designed for dairy and environmental monitoring – developed for dairy products and surface environmental testing where rapid coliform screening is important.
• Ambient storage – store at +1 °C to +30 °C, helping to simplify lab workflows.
• Validated performance – MicroVal certified for added confidence in routine testing programs.
