Compared to other current testing methods, Colichrome™ MF ECC- A offers rapid testing with clear and easy-to-read results. This test medium differentiates Coliform bacteria from the non-coliform Aeromonas spp., so that false-positive readings due to Aeromonas spp. are eliminated.
- Extremely accurate and easy to understand results
- Results in 24 hours or less
- Free technical support
- 10 tests/bottle
- E. coli appears as dark blue dots, Coliform appears pink/red dots, Aeromonas appears as yellow dots (Each “dot” represents one bacterial colony or “CFU”)
How It Works
Colichrome™ MF ECC-A Protocol as for other membrane filters (MF) media, following the standard methodology using a membrane filtration device
However, unlike other testing methods where results are difficult to read and understand, Colichrome™ MF ECC-A results are clear and precise. After incubating your sample for 24-48 hours at 35° C, any E. coli colonies will appear as dark blue dots. Other Coliforms (Enterobacter, Citrobacter and Klebsiella spp. & others) will appear as dark pink/red dots. Aeromonas will appear as pale yellow dots. The colonies may continue to grow in size and intensity up to 36-48 hours.

Additional Equipment Needed
Colichrome™ MF ECC-A is a membrane filtration medium that requires the standard equipment for any membrane filtration process. If you’re looking for a method of detecting Coliform, but do not have the standard equipment, you might be more interested in our self-contained R-CARD™ testing method that requires minimal additional equipment.
