Using Petri Dishes in Microbiology Classrooms
Petri dishes are essential tools for growing and observing microorganisms in controlled laboratory environments. In secondary school science and tertiary microbiology settings, 90 mm petri dishes are commonly used for culturing bacteria and fungi on nutrient agar media. Disposable plastic dishes are ideal for classroom use where sterility and convenience are important, while reusable glass petri dishes suit laboratories with sterilisation facilities.
Pre-poured nutrient agar plates allow safe and efficient classroom investigations into bacterial growth, hygiene testing, environmental sampling, and food microbiology studies. When paired with spreading tools such as Drigalski spatulas, sealing film, and petri dish racks, students can conduct structured experiments while maintaining proper contamination control.
Common Classroom Applications
