PD90

The PD90 is the 90 × 15 mm standard petri dish — the most commonly specified format in clinical microbiology, environmental monitoring, and food safety testing worldwide. Its larger growth surface compared to 60 mm dishes accommodates higher inoculum volumes and allows clearer spatial separation between colonies during isolation streaking, reducing ambiguity in colony counting and morphology assessment at high sample loads.

◆ 90 × 15 mm standard format — the globally adopted size for clinical specimen culture, environmental air and surface sampling, and food microbiological testing; directly compatible with most automated colony counters and incubator stacking systems

◆ Larger growth surface vs. 60 mm — accommodates higher inoculum volumes and provides greater spatial separation between colonies, reducing confluence interference during isolation streaking and counting

◆ Non-sterile — optimized for high-throughput labs that prepare and autoclave their own agar plates in bulk, significantly reducing per-plate cost at scale

◆ High-clarity PS — transparent base and lid for direct visual and instrument-based colony enumeration without dish transfer

◆ Smooth raised rim — consistent dish-to-lid fit minimizes condensation pooling and ensures stable stacking during incubation

◆ Hot agar compatible — stable at standard pour-plate temperatures (45–55°C); no deformation during media solidification

◆ DNase/RNase-free, endotoxin-free — 20 pcs/bag, 25 bags/case
