Card Size: 3.5"x 4"      Capacity: 1mL     STORAGE CONDITIONS AND STORAGE LIFE

A revolution in bacteria testing, the R-CARD® test method offers the most convenient, streamlined way to detect not only the presence of E. coli, but also the number of colonies.

  • Completely self-contained, requiring almost no additional equipment
  • Extremely accurate and easy to understand results
  • Fast results in 15-24 hours (incubated)
  • E. coli will show up as green/turquoise dots


How It Works

Unlike most E. coli testing kits on the market, R-CARD® rapid tests require almost no additional equipment and offer an extremely easy user-experience. Simply lift the R-CARD® E. coli clear film and deposit 1 mL of your liquid 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 easy to transport and use in the field.

For quickest results, it’s best to incubate your sample at 35±0.5°C for 15-24 hours. To read your results, simply count the number of green/turquoise dots which show the number of E. coli colonies.

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 stored in a coat or backpack pocket.

It’s also incredibly easy to read R-CARD® results. They not only detect the presence of E. coli, but also the number of colonies. Simply count the number of green/turquoise 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 (15 to 24 hours with an incubator).

Wonderful product for our school STEM program

We find that the R cards provide us an inexpensive tool for presenting water quality sampling to students in our school STEM program. We are also able to demonstrate how science is moving away from the petri dish model of processing samples.

Easy to use, less plastic

My volunteers love using R-Cards to test E. coli levels in our streams. Much easier to use than petri dishes, plus less plastic waste! Virginia DEQ has given us the thumbs up as well. Highly recommend!
