Purpose of inspection

Features of the membrane filter method  This is an inspection method used when inspecting liquid samples with relatively few microorganisms such as water and beverages. The bacteria are captured with a membrane filter and transferred to the MC-Media Pad to measure the number of colonies.

Inspection method

1) Prepare the following equipment.

2) Add 1 ml of sterilized water to MC-Media Pad, leave it for at least 15 minutes with colosing the cover film.

3) Set the sterilized membrane filter and filter the sample solution. Record the volume of filtered solution.

4) Put the filtered membrane on the MC-Media Pad, close the cover film.

5) Put this MC-Media Pad into incubator, incubate at the temperature and time specified for each product.

6) Take out the MC-Media Pad from incubator, count the number of colonies with interpretation for each product.

7) Culculate tne number of microorganisms in the sample solution with counted colonies and filtered volume.
