Equipped with three evenly spaced gas-permeable vents (usually arranged in a triangular pattern) to optimize air exchange while minimizing contamination risk.
Anti-condensation coating to prevent droplet formation on the lid.
Vents are typically covered with a hydrophobic microporous membrane (e.g., PET or PVDF) to allow CO₂/O₂ diffusion and maintain humidity balance.
>> Purpose
The petri dish is widely used in microbiology, cell culture, scientific research and experiments, industrial production and environmental monitoring and other fields.
