Pick the Right One at a Glance – Color-coded MC-Media Pads®

Designed for your convenience

The MC-Media Pad® is designed for convenient and rapid routine testing of microbial contaminations in your food and beverage products. The pads are coated with a growth medium and chromogenic substrates for specific detection allowing faster results and improved readout. When the sample is applied, the liquid spreads evenly on the pad by capillary action. No additional working steps are required, improving the workflow and reducing the risk of contamination. The transparent cover film can be easily opened and closed with one hand, and the color coding ensures that you can always pick the right one at a glance. MC-Media Pads® comply with international standards (AOAC, MicroVal) and are quality controlled with strain selection according to ISO 11133.

Enjoy the benefits of a ready-to-use method

Why stick to traditional media plates if there is an alternative available which can improve your workflow, while providing accurate and reliable results? MC-Media Pads® are ready-to-use and provide additional features for your financial benefit and cost-efficiency:

  • Save space in your fridge and incubator
  • Go green & gain: reduce your environmental impact
  • Improve your inventory management with a shelf-life of up to 36 months
  • Comply with regulations
  • No spreading device required
  • Simplify your workflow:

Workflow example with MC-Media Pad® Coliform


Open the cover film diagonally, then inoculate sample to center of the pad. After inoculation, sample will diffuse automatically into the whole pad. Close the cover film and incubate according to application conditions. Count.

We challenged our MC-Media Pad® with different food and beverage matrices and compared their performance to other convenient media products. Find out how they performed in our study.

How to use MC-Media Pad®

Hygiene monitoring with MC-Media Pad®

Our MC-Media Pad® does not only streamline your indicator organism testing workflow, it is also suitable for different hygiene monitoring applications, like passive air, personnel and surface monitoring. Read our study to learn more.

Just pick the color you need

The MC-Media Pad® portfolio offers a broad range of products for the main applications in the food and beverage industry. Use of chromogenic indicators leads to specific results and allows for better interpretation. Just incubate at 25 °C or 35 °C for 24-48 hours to detect dedicated contaminants.


Rapid Aerobic Count

Incubation: 35 °C, 24 hoursReadout: All grown colonies develop reddish color. Regardless of strength of color, all grown colonies should be counted.

Short time to result


Incubation: 35 °C, 24 hours  Readout: Coliforms produce blue/blue-green colored colonies due to β-galactosidase production. Gram-negative non-coliform bacteria form colorless colonies. Regardless of strength of color, all blue/blue-green colored colonies should be counted.

Easy readout thanks to blue colored colonies
E.coli and Coliform

Incubation: 35 °C, 24 hours Readout: Coliform bacteria form blue/blue-green colored colonies due to β-galactosidase production, whereas E. coli will produce indigo to purple colored colonies due to specific β-glucuronidase. Gram-negative non-coliform bacteria forms colorless colonies. Regardless of strength of color, all colored (blue/blue-green and purple/navy) colonies can be determined as total coliform. Only purple to navy colored colonies should be counted as E. coli.

Chromogenic approach: easy differentiation between E.coli and Coliform colonies & no gas formation required
Yeast & Mold

Incubation: 25 °C, 48 hours Readout: All grown colonies will develop a reddish color. Regardless of strength of color, all grown colonies should be counted. Yeast and Mold can be easily distinguished by their different morphologies. Yeasts will appear as circular reddish colored colonies, whereas mold colonies are also round and reddish in color, but will appear more diffuse with fuzzy edges.

Time to result for various matrices in 48 hours, appropriate sample area to avoid spreading of the molds and ensure valid readout
Staphylococcus aureus

Incubation: 35 °C, 24 hours Readout: S. aureus form circular light blue/blue colored colonies. Even though other bacteria are inhibited strongly, some bacteria (especially Bacillus species) can form gray/black colored colonies.

Comfirmation test can be easily performed, e.g. with a coagulation test
