DNP Film·Media Culture Medium Plate

Microbiology Test Piece Film·Media of DNP Film·Media Culture Medium Plate

Make food microbiological testing much easier and more effective

Compared with the agar medium, our bacterial culture media plate makes the detection of food microorganisms easier, more standardized, and more efficient, but without pollution.

1. Culture media ready to be used after opening;

2. Colonies easy to see;

3. Reduce the culture area and waste.


1) The product is used for the microbiological examination of foods and beverages, and cannot be used clinically.

2) Do not open the tectorial membrane before transplanting the sample.

3) Do not use expired products.

4) Do not use products that are damaged, deformed, discolored, dirty, or foreign matters.

5) Do not expose the product to ultraviolet light or sunlight.

6) Do not press the film after the sample liquid is dropped. This will cause the sample solution to overflow to the outside of the culture area.

7) When the sample solution overflows from the culture area, replace it with a new one.

8) If the product enters the eye or mouth, immediately wash it with water and go to the hospital.

9) When using the product, it is susceptible to microbial contamination. Perform specific operations under the guidance of relevant qualified personnel.

Performance Characteristics of DNP Film·Media Culture Medium Plate

Medium ready to be used after opening

The product does not require pre-modulation and autoclaving, just check it. No need for mixed release. Double layer coverage is easy to operate which will improve working efficiency.

Colonies easy to see

Due to the use of the color former, the colonies are clearly visible and easy to discriminate. It is beneficial to improve the working efficiency of counting bacteria and working standardization. In addition, since Film·Media AC is a bacillus, it is one of the characteristics that the coloring penetration is relatively small.

Reduce the culture area and waste

Compared with the culture dish, it can be reduced to about 1/15~1/20, which can reduce the storage space and the waste after use.

Variety introduction

The Culture Media Plate Film·Media is not considered for personal visual differences but produced according to the coloring universal design that most people can easily see, and is also certified by the NPO corporate coloring general design agency.

SA uses chromogenic enzymes to easily determine and count bacteria.

When the bacteria number is large, please perform statistics in the grid on the film (1cm × 1cm).

Multiply the bacteria number in a grid by the total grids number

5. Fishing for colonies which can be re-cultured

Remove the bacteria by opening the membrane.

Colony Count System

By using the colony counting system (dedicated scanner and application), high-resolution images can be analyzed, and automatic counting and inspection result image storage management can be realized in a short time, which can improve the counting efficiency.
