In microbiology petri dishes are particularly used when working with nutrient media. They are part of the basic equipment of a modern laboratory and are needed for a variety of applications - but not every kind of petri dish is suitable for every application. Between the different industries and fields of application, lab users should clarify some questions before purchasing the product:
✔ What size does the surface need to be? → Petri dishes can be found in different sizes 35, 60, 94, 100 and 145 mm diameter.
✔ 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.
✔ Is a good gas exchange required? → In this case the choice falls on petri dishes with venting lobes.
✔ 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.
✔ Is the petri dish used for germ counting? → For this application petri dishes with subdivable 10 mm squares are suitable for a rapid evaluation.
✔ Is the petri dish required for hygienic control? → Above all, contact clamps are used, which are also available with dividers and ventilation lugs.
