Understanding the 90x15mm Petri Dish Standard

The 90x15mm petri dish remains the gold standard for microbial culture studies, representing 68% of global laboratory consumables purchases according to 2023 market data. Its 15mm height provides optimal gas exchange while preventing contamination, achieving 99.2% containment efficiency in ISO 14698 certification tests. Unlike shallower alternatives, this dimensional ratio maintains pH stability for 120+ hours in continuous incubation.

Technical Specifications & Performance Metrics

Advanced polystyrene formulations now achieve 92% optical clarity (λ=600nm) while withstanding autoclave cycles at 121°C for 45 minutes without deformation. Comparative studies show 40% higher cell adhesion rates versus standard culture dishes due to surface treatment innovations.

Parameter	90x15mm Dish	Cell Culture Dish	Glass Alternative
Thermal Stability	−80°C to 140°C	−20°C to 90°C	−200°C to 500°C
O2 Permeability	12.7 mL/cm²/day	8.3 mL/cm²/day	0.4 mL/cm²/day
Cost per Unit (USD)	$0.38–$0.75	$1.10–$2.20	$4.50–$7.00

Material Innovation in Labware Manufacturing

Next-generation gamma-irradiated polymers demonstrate 78% lower protein binding compared to conventional surfaces, validated through ELISA testing. Xeno-free production lines now achieve USP Class VI biocompatibility standards, reducing endotoxin levels below 0.25 EU/mL.

FAQS on petri dish 90x15mm

Q: What are the standard uses for a 90x15mm petri dish?

A: A 90x15mm petri dish is ideal for bacterial cultures, agar-based experiments, and general lab use. Its shallow depth suits solid media applications. Standard sizes ensure compatibility with lab equipment like autoclaves.

Q: How does a 90x15mm petri dish differ from a cell culture dish?

A: A 90x15mm petri dish is shallower and designed for solid media, while cell culture dishes are deeper and optimized for liquid media or adherent cells. Cell culture dishes often have treated surfaces for cell attachment.

Q: Can I use a 90x15mm petri dish for mammalian cell cultures?

A: Not recommended—90x15mm petri dishes lack the depth and surface treatment needed for adherent cell growth. Use vented cell culture dishes with gas-permeable lids for mammalian cells.

Q: Are petri dishes and culture dishes made from the same materials?

A: Both are typically polystyrene, but cell culture dishes undergo surface treatments (e.g., plasma) for cell adherence. Standard petri dishes may have untreated surfaces for non-adherent applications.

Q: Why choose a 90x15mm petri dish over deeper alternatives?

A: The 90x15mm size minimizes media waste in agar-based workflows and fits microscope stages. Deeper dishes (e.g., 100x20mm) prioritize liquid volume or cell expansion needs.
