Petri dishes are among the most widely recognized laboratory items, used for cell culture, microbiology, and sample handling. While their design is simple, choosing the right petri dish — correct size, surface treatment, and sterility level — can significantly affect experimental outcomes.
Standard Sizes
| Diameter | Growth Area | Typical Use |
|---|---|---|
| 35 mm | 8 cm² | Small-scale cultures, immunofluorescence |
| 60 mm | 21 cm² | Routine cell culture, cloning |
| 100 mm | 55 cm² | Standard adherent cell culture |
| 150 mm | 148 cm² | Large-scale culture, protein extraction |
TC-Treated vs Non-Treated
TC-treated (Tissue Culture treated) dishes undergo plasma or corona discharge treatment to render the polystyrene surface hydrophilic, promoting cell attachment. Use TC-treated for adherent cell lines. Non-treated dishes are suitable for suspension cells and microbiology.
Vented vs Non-Vented
Vented dishes feature a small ridge on the lid that allows gas exchange during incubation. Non-vented dishes are best for sealed or low-gas-exchange applications. JWRESEARCH offers both options to match your specific culture requirements.
Sterility Assurance
All JWRESEARCH petri dishes are gamma-irradiated and certified sterile. They are packaged in stacks of 10 or 20, wrapped in tamper-evident bags for contamination-free storage.
