Card Size: 3.5"x 4" Capacity: 1mL STORAGE CONDITIONS AND STORAGE LIFE
A revolution in Salmonella testing, the R-CARD® test method offers the most convenient, streamlined way to detect not only the presence of Salmonella and E.coli in one test but also the number of colonies, in as little as 18 hours!
- Completely self-contained, requiring almost no additional equipment
- Extremely accurate and easy to understand results
- Fast results in 18 hours (incubated)
- Free technical support at any step of the process
- Salmonella will show up as black dots
How It Works
Simply lift the R-CARD® Salmonella EC clear film and deposit 1 mL of sample on the card. Then release the clear film so it can fall back on top of the card, covering your sample. Within 1-3 minutes, the liquid sample will solidify between the two layers. This prevents it from dripping or leaking, making R-CARD® rapid tests incredibly clean and easy to use.
For the quickest results, it’s best to incubate your sample at 35±5°C for 18-24 hours (Salmonella and E.coli grow quickly in this temperature range). Results will start showing in as little as 18 hours, but we recommend waiting until 24 hours to get an accurate count of colonies. To read your results, simply count the number of black dots which show the number of Salmonella colonies, and green/teal dots which show the number of E.coli colonies. Waiting to count colonies beyond 30 hours will become difficult as Salmonella colonies grow and potentially overlap.

Additional Helpful and Important Information
Why R-CARD® Rapid Tests Are Better Than Competing Products
R-CARD® rapid tests offer a revolution in convenience without sacrificing accuracy. The cards are completely self-contained and don’t require Petri dishes, agar, or other gear that’s fragile and prone to leak. Simply place your sample on the card and wait 1-3 minutes for the liquid sample to solidify between the two layers. This prevents it from dripping or leaking. Cards can easily be stacked in the incubator, reducing the space required for your testing needs.
It’s also incredibly easy to read R-CARD® results. They not only detect the presence of Salmonella and E.coli but also the number of colonies. Simply count the number of black dots that appear after the appropriate incubation period.
Additional Equipment Needed
While the R-CARD® rapid tests are completely self-contained, you will need a sterile dropper or syringe to dispense your liquid sample onto the card. Once your sample is collected, it’s recommended to use an incubator to rapidly decrease the time it takes to view results.
