HardyCHROM™ ECC (E. coli and Coliform), contact plate with Lok-Tight™ friction lid, order by the package of 10, by Hardy Diagnostics
MINIMUM ORDER: 10 PACKS

For E. coli - Coliforms!

HardyCHROM™ ECC is a chromogenic media recommended for the detection, differentiation, and enumeration of Escherichia coli and other coliforms in food, water, or environmental samples based on colony color. Each contact plate has a specified grid molded into the bottom of the plate for enumeration of microbial colonies growing on a variety of surfaces.

Routine testing to assess the sanitary quality of food and water is directed at the detection and enumeration of indicator organisms rather than pathogens. The coliform group of organisms is recognized as the principal indicator of unsanitary conditions. Coliform organisms are characterized as gram-negative, lactose-fermenting rods. They are present in the intestinal tract of man and other animals, and non-fecal coliforms are found in many areas of the environment, including in soil and on plants.

Features and Benefits:

  • E. coli can be identified as pink to violet colored colonies on the plate.

  • Other coliform bacteria will appear as turquoise colonies.

  • Organisms other than coliforms or E. coli (including approximately 4% of E. coli strains and most O157 strains) will appear as white or colorless colonies.

  • Selective agents have been added to inhibit the growth of gram-positive and other non-coliform bacteria.

  • Each contact plate has a specified grid molded into the bottom of the plate for enumeration of microbial colonies growing on a variety of surfaces.

Our Contact Plate features:

  • Friction lid
    The friction lid design keeps lids in place before sampling.

  • Lok-Tight™ Locking Lid
    An optional locking feature means lids stay secured post sampling and during transport to your lab.

  • Molded Grid
    Each plate has a grid molded into the bottom of the plate to aid in the counting of microorganisms.

  • Certificate of Analysis
    Available online for each lot.

This media is to be stored and incubated in the dark. If you have a light in your refrigerator, incubator, or you leave the media exposed to light on the bench top, Hardy Diagnostics offers free Blok-Boxes. Blok-Box is a reusable cardboard box that holds one sleeve of ten petri plates.

Please ask Customer Service if you would like a free Blok-Box sent with your order. Customer Service – (800) 266-2222
