The product is widely used in:
- Food & beverages
- Drinking water, domestic water
- Cosmetics
- Animal feed
- Microbiology testing laboratories
1. Advantages of using Compact Dry
- No need to prepare media (saves time)
- Fewer handling errors
- Easy to use even in small labs
- Fast, easy-to-read results
- Saves testing costs
👉 This is why more and more businesses are switching to the Compact Dry rapid microbiological testing guide instead of traditional methods.
2. How to use Compact Dry – Standard procedure steps
Step 1: Sample preparation
- Take the sample to be tested (food, water, surface…)
- Dilute the sample with a suitable solution (0.85% NaCl, BPW…)
- Shake well to homogenise the sample
Step 2: Inoculating the sample onto the plate
- Open the Compact Dry plate lid
- Use a micropipette to draw 1 ml of sample
- Pipette it directly into the centre of the plate
- The sample spreads evenly on its own thanks to the dry medium structure
Step 3: Close the lid and incubate the sample
- Close the lid immediately after inoculation
- Place the plate in the incubator

4. Notes when incubating the sample (Extremely important)
To ensure accurate results when applying how to use compact dry, note the following:
- Common incubation temperature: 30–37°C (depending on the parameter)
- Incubation time: total microorganisms: 24–48h, Coliform/E. coli 24h
- Place the plate upside down to avoid water condensation
- Do not stack too many plates on top of each other
- Avoid shaking during incubation
5. How to read Compact Dry results accurately
After incubation, read the results:
* General principles:
- Count the number of colonies appearing on the plate
- Each colony = 1 CFU (colony forming unit)
* Colour distinction (depending on the plate type):
- Coliform: red and pink colonies are Coliforms.
- E.coli: all blue and purple colonies are E.Coli.
* Calculation:
- See how to calculate colonies here.
6. Common mistakes in rapid microbiological testing
- Inoculating the wrong volume (not a full 1 ml)
- Not diluting the sample → bacterial overload
- Incubating at the wrong temperature
- Reading the colony colours incorrectly
- Storing the plate incorrectly
👉 These mistakes can distort the results of the rapid microbiological testing guide, so special care is needed.
7. Conclusion
Understanding clearly how to use compact dry will help businesses:
- Shorten testing time
- Save up to 50% of costs
- Ensure high accuracy
- Standardise the microbiological testing process
👉 If you are looking for a solution for fast, simple and effective microbiological testing, then the Compact Dry plate is the optimal choice.
