Flat Surface for Clear Colony Observation
Petri dish flatness directly affects colony observation and experimental results. Taizhou KENI Mould Co., Ltd. designed this petri dish mould for high‑quality microbiology lab consumables. Standard cavities are 8 or 16 for the Φ90mm size. Outer diameter tolerance is ±0.03mm. Surface flatness is ≤0.02mm. This ensures even medium distribution and no image distortion. Dish wall thickness is 1.0 to 1.5mm. Cycle time is 15 to 20 seconds per shot. Surface finish is Ra ≤0.05μm. The mold fits 200T to 280T injection machines. This petri dish mould gives you clear, flat dishes that meet lab standards.
We Test Flatness on Every Dish
We inspect every petri dish mould carefully. Flatness is tested dish by dish. Our 10‑person R&D team can help you optimize the dish structure. We send you progress updates during production. After delivery, our after‑sales team visits you regularly. If problems occur, we solve them quickly. We accept third‑party inspections. We offer a one‑year free warranty and lifetime maintenance. Repeat orders save 7 to 10 days. This product is designed for microbial and cell culture applications.
