Easy Plate SA

Easy Plate
is a convenient, prepared media plate with no need for media preparation or sterilization. Easy Plate is an easy to use alternative to in-house media preparation using traditional plated media that saves time, labor and reduces waste. Using an Easy Plate as a food microbiological test kit – which is about 1/20 volume of the traditional petri dish – saves space and allows you to run more tests with your current incubator space. Easy Plates come ready-to-use and immediately after opening the package you can place a sample suspension onto the media and start incubation.

  Easy Plate SA

Easy Plate SA is an AOAC PTM certified custom media formulation for cultivation of Staphylococcus aureus. A microbial test kit that contains a chromogenic substrate that produces easily distinguishable brightly colored blue colonies, allowing you to easily identify and quantify Staphylococcus aureus. Compared to Baired-Parker agar and Mannitol salt agar with egg yolk which takes 48 hrs, Easy Plate SA incubation time is reduced to in 24±1 hrs. Easy Plate SA also contain inhibitors reducing the growth of non- Staphylococcus aureus, but if they grow, the colonies will exhibit a pink to red-violet color making them easy to distinguish. Easy Plate SA is AOAC PTM certified and sold in packages of 100 tests in 4 separate bags containing 25 tests each. The shelf life of 12 months when stored unopened at 2-8℃.


1. Easily distinguishable brightly colored colonies at 24 hours

  • Identification is easier compared to agar count media, since the color change makes it unnecessary to confirm the egg-yolk reaction.
  • The incubation time is decreased by half to 24 hours, improving the time to report results.
  • Only one sheet is required when using Easy Plate, while the surface plating method requires three or more plates.

2. High specificity

  • Some S. aureus that exhibit negative egg yolk reactions on conventional agar media can be detected on Easy Plate.
  • Many bacteria other than S. aureus are Inhibited by the selective media. Non-Staph aureus colonies that do develop, are easy to identify due to their pink to red-violet coloring.


3. High correlation with the plate count agar

High correlation with the plate count agar in various foods.

S. aureus colonies that develop will exhibit a blue coloring making them easy to identify and count. The SA Easy Plate media is inhibitory for other bacteria but, if they develop, they should exhibit a pink to red-violet coloring making discrimination easy.
