Perfect for home labs, classroom experiments, or serious scientific work, these sterile petri dishes are exactly what you need for growing and observing microorganisms. Each dish measures 90x15mm with a handy 3-section design that lets you run multiple tests simultaneously. They're ethylene oxide sterilized and come with secure lids to keep your samples contamination-free during incubation. What really sets these apart is the quality - at 15 grams each, they're thicker and more durable than many other brands that only weigh 12 grams. Use them with potato dextrose agar or other nutrient mediums to culture bacteria, mold, or other tiny organisms. They're compatible with all standard lab supplies like specimen cups and parafilm tape. The included 'dish buddy' makes handling multiple plates so much easier. Whether you're a science teacher, student, hobbyist, or professional researcher, these reliable petri dishes deliver the performance you need for successful experiments every time. Your microbiology projects just got way more professional!
