Features:
The BostonMed Supply 90mm x 15mm Non-Ventilated Petri Dishes are manufactured for laboratories where contamination control, sample integrity, and repeatable results are the priority. Each dish is designed for a secure, sealed incubation environment — making them the preferred choice for moisture-sensitive cultures and applications where airborne contamination must be minimized.
Our dishes are made from durable, medical-grade polystyrene with high optical clarity, giving you a clear view of colony growth without removing the lid. The 90mm format is the most widely used size in routine microbiology, fitting standard incubators, colony counters, and imaging systems.
Ready to use straight out of the box — no preparation required.
Key Features:
- Non-ventilated lid creates a fully sealed environment that retains moisture and reduces contamination risk during incubation
- Raised rim on the lid ensures a secure, stable fit and allows safe stacking without slipping
- High optical clarity allows direct observation of cultures without opening the dish
- Medical-grade polystyrene — strong, chemically stable, and compatible with standard laboratory stains and reagents
- Compatible with most laboratory incubators, colony counters, and analytical instruments
- Ready to use — individually manufactured to consistent dimensional tolerances for reliable, repeatable results
