Petri Dishes 20 Pack 90mm Polystyrene

$9.99

90mm Petri Dishes – Lab Standard
These dishes measure 90mm x 15mm and are molded from clear, durable polystyrene, giving you reliable visibility when working with cultures. Each plate provides a spacious surface area that’s well-suited for agar pours and mycelium transfers.

Key Features:

  • Vented lids – Each dish has three small air vents to allow for gas exchange. This helps your cultures breathe while keeping condensation and contamination risks lower during incubation.

  • Clarity and durability – The transparent polystyrene makes it easy to track growth and spot contaminants early, while the rigid walls hold up through handling and stacking.

Use in cultivation:
These are standard dishes for anyone pouring agar—whether you’re cloning mushrooms, starting spores, or keeping a clean culture library. Best practice is to pour in a sterile environment (still air box or flow hood), allow plates to set fully before use, and store them inverted to minimize condensation drip.
