Need to buy petri dishes for long-term projects or institutional programs? We support wholesale lab orders and recurring shipments to ensure you never run short.
Petri Dish + Nutrient Agar = Culture Platform
When filled with nutrient agar, the petri dish transforms into a growth medium for bacteria, yeast, and mold. It provides a flat, sterile surface where microbes can thrive and be easily observed. This setup is foundational for microbial diagnostics, research, and teaching.
If you are using agar powder or pre-poured agar plates, our dishes are designed to withstand warm agar temperatures and maintain a flat surface to prevent uneven distribution.
Types of Petri Dishes We Offer
Choose from a wide selection of lab-grade petri dishes:
-
Standard Dishes: 90mm and 100mm clear plastic dishes for routine culture work
-
Vented Lids: Allow air exchange to support aerobic growth
-
Non-Vented Lids: Reduce evaporation for long-term incubation
-
Tissue Culture-Treated: Surface-modified for adherent cell growth
-
Segmented Dishes: With two or more compartments for comparative cultures
Each option is sterilized, individually wrapped or sleeve-packed, and ready to use upon arrival.

FAQs
Where to buy petri dishes?
You can buy petri dishes directly from Astor Scientific’s online store. We ship across the U.S. and offer sterile, lab-ready options in multiple sizes.
What is a petri dish?
A petri dish is a shallow, circular plastic or glass container used to grow and observe microorganisms under laboratory conditions. It’s typically filled with agar, a gel-like substance rich in nutrients.
How to grow bacteria in a petri dish?
To grow bacteria, pour warm nutrient agar into a sterile petri dish and let it solidify. Inoculate the surface with a sample, close the lid, and incubate the dish at 37°C for 24–48 hours. Avoid opening the dish unnecessarily to prevent contamination.
What is a nutrient agar petri dish?
A nutrient agar petri dish contains a mixture of water, agar, and nutrients that support bacterial growth. It’s commonly used in microbiology to culture and study microbial colonies.
