Compact Dry CFR plates provide rapid detection and enumeration of coliforms, with a workflow designed especially for dairy testing. Coliform colonies appear blue to blue-green after incubation, while non-coliform organisms that may grow typically remain white and are not counted as coliforms.
Use Compact Dry CFR to support rapid coliform screening, sanitation verification, and quality assurance programs where faster insight is needed. Early color or fluorescence can indicate a presumptive positive result, while countable results are read after 16-18 hours of incubation at 35 +/- 1 C.
Key Benefits
- Rapid results: presumptive positive detection may be possible in as little as 6 hours, with enumeration after 16-18 hours at 35 +/- 1 C.
- Simple workflow: pipette 1 mL of diluted sample directly onto the self-diffusing plate; the dehydrated medium rehydrates into a gel within seconds.
- Clear interpretation: count blue to blue-green colonies as coliforms after the full enumeration incubation period.
- Early screening support: blue/green color development or blue/white fluorescence under 365 nm UV light can support presumptive detection during early incubation.
- Dairy-focused validation: MicroVal certified for raw milk and dairy products, and heat-processed milk and dairy products.
- Ambient storage: store at 1 C to 30 C; no refrigeration required.
