- with or without venting lugs
- Good stackability
- various sizes & diameters
- Graduation & subdivision in 10-mm-squares possible
- some dishes also available as macro plates
Aside from the petri dishes of the manufacturers such as Greiner Bio-One, Duran and Nunc Thermo Scientific you will find racks and other accessories in this category.
Application
In microbiology petri dishes are particularly used when working with nutrient media.

Checklist
- Surface: What size does the surface need to be? → Petri dishes can be found in different sizes 35, 60, 94, 100 and 145 mm diameter.
- Temperature: What is the temperature of the agar? → When working with hot agar, it is essential that the petri dishes are made of durable material. In the Analytics-Shop, you will find exclusively robust petri dishes made of heat-resistant polysterol.
- Gas exchange: Is a good gas exchange required? → In this case the choice falls on petri dishes with venting lobes.
- Parameters: How many parameters must be observed at the same time? → For the simultaneous investigation of various parameters, petri dishes with two or three separated compartments are suitable.
- Germ counting: Is the petri dish used for germ counting? → For this application petri dishes with subdivable 10 mm squares are suitable for a rapid evaluation.
- Hygienic control: Is the petri dish required for hygienic control? → Above all, contact clamps are used, which are also available with dividers and ventilation lugs.
