Performance Characteristics of Contact  5x5

1. It is widely used in environmental sanitation, apparatus, sedimentation bacteria and hand colony inspection.

2. It can be used directly after opening, no need to prepare medium which saves time and effort.

 

3. the medium area is 24 cm2. It is divided into several small cells which are easy to count.

 

Agar Medium Type

AC Standard Plate Counting Agar Medium

Used for the identification of the total bacteria number.

Escherichia coli and coliforms are simultaneously detected.

E.Coli colonies are blue to light purple.

Coliform colonies are red to purple.

 

Other intestinal bacterial colonies were milky white.
