Card Size: 3.5"x 4" Capacity: 1mL STORAGE CONDITIONS AND STORAGE LIFE
A breakthrough in Orange Serum media, the R-CARD® test method offers the most convenient, streamlined way to detect not only the presence of aciduric microorganisms, but also an accurate count of the number of colonies! Lactobacillus spp., yeasts, and molds are commonly found in/on fruit juice and fruit concentrates, in particular citrus fruits and may be involved in product rotting or spoilage.
- Completely self-contained, requiring almost no additional equipment
- Extremely Accurate and easy to interpret results
- Results in 40-72 hours (incubated)
- Microorganisms show as green/teal, pink-red, and magenta colonies
How It Works
Unlike other Orange Serum media on the market, R-CARD® tests require almost no additional equipment and offer an extremely easy user-experience. Simply lift the R-CARD® Orange Serum 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 most accurate results, it’s best to incubate your sample at 30-35°C for 40-72 hours. Results will start showing in 40 hours, but we recommend waiting until 72 hours to get an accurate count of colonies. To read your results, simply count the number of all colored dots, which are the number of microorganisms colonies.

Why R-CARD® 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 the R-CARD’s results. After the appropriate incubation time, simply count the green/teal, pink and magenta dots for the number of microorganisms colonies.
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.
