| Automation Level | manual |
150mm diameter petri dishes fabricated from crystal-clear polystyrene (PS) for large-scale microbial cultivation and screening applications. Each dish provides 176.7 cm² of growth surface area, optimized for colony isolation, morphology assessment, and high-throughput screening protocols requiring expanded workspace. Sterile packaging ensures aseptic conditions for immediate use in microbiological workflows.
The crystal-clear PS construction enables unobstructed visual examination of colony characteristics, growth patterns, and morphological features under standard laboratory lighting and microscopy conditions. The 150mm diameter accommodates dilution plating techniques, large sample volumes, and applications requiring spatial separation of multiple test conditions on a single plate.
How It Works
Petri dishes function as controlled cultivation environments that maintain sterile conditions while providing optimal surface area for microbial growth. The polystyrene construction offers chemical inertness and optical clarity, preventing interference with growth media while enabling visual monitoring of colony development. The dish geometry creates a shallow, enclosed environment that maintains humidity while allowing gas exchange through the slight gap between base and lid.
The 150mm diameter provides 176.7 cm² of growth surface, accommodating dilution series, multiple test conditions, or high-density sampling applications. The crystal-clear PS material transmits visible light effectively, enabling direct observation of colony morphology, pigmentation, and growth patterns without removing the protective lid. The sterile packaging eliminates pre-use contamination risks in aseptic workflows.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Diameter Size | 150mm diameter providing 176.7 cm² surface area | Standard models typically offer 90mm (63.6 cm²) or 100mm (78.5 cm²) surface areas | Larger surface area enables higher dilution factors and improved colony separation for accurate enumeration |
| Material Clarity | Crystal-clear polystyrene construction | Standard-grade PS may have slight opacity or color variation | Enhanced optical clarity enables detailed morphological assessment without lid removal |
| Sterility Assurance | Sterile packaging for immediate use | Some suppliers offer non-sterile dishes requiring pre-use sterilization | Eliminates sterilization steps and contamination risks in time-sensitive protocols |
| Application Scope | Optimized for large colony screening applications | Smaller dishes limit dilution range and colony separation | Accommodates complex plating schemes and high-density sample processing |
These 150mm sterile petri dishes provide expanded cultivation area with crystal-clear optical properties for demanding microbiological applications. The large diameter enables advanced dilution techniques while maintaining sterile packaging convenience for immediate laboratory use.
Practical Tips
Pour medium at 50-55°C to prevent thermal shock while ensuring proper flow characteristics for bubble-free solidification.
Why: Optimal temperature prevents dish warping while achieving uniform medium thickness across the large surface area.
Store unused sterile dishes in their original packaging in clean, dry conditions away from temperature fluctuations.
Why: Maintains sterility integrity and prevents package seal compromise that could introduce contamination.
Allow solidified plates to dry for 10-15 minutes at room temperature before inoculation to remove surface moisture.
Why: Prevents sample spreading artifacts and ensures proper colony morphology development during incubation.
If condensation forms on the lid during incubation, briefly invert plates or adjust incubator humidity settings.
Why: Excessive condensation can interfere with colony observation and potentially cause sample contamination through droplet formation.
Use the large surface area to create grid patterns or sector divisions for organized sample placement during comparative studies.
Why: Systematic organization improves data accuracy and enables efficient documentation of results across multiple conditions.
Handle used dishes as potentially infectious material and dispose according to institutional biosafety protocols.
Why: Cultured microorganisms may pose health risks and require appropriate decontamination before disposal.
Label dishes on the base rather than the lid to prevent mix-ups during handling and observation procedures.
Why: Base labeling ensures identification remains with the culture surface and prevents errors during lid removal or exchange.

Compliance
What volume of medium should be used with 150mm dishes?
Typically 50-60 mL of molten agar medium provides appropriate depth (approximately 3-4 mm) for optimal growth conditions and colony isolation.
Can these dishes withstand autoclaving temperatures?
Polystyrene petri dishes are designed for single use and should not be autoclaved. Use sterile, disposable dishes for each application to maintain aseptic conditions.
How do these compare to 90mm dishes for colony counting?
The 150mm diameter provides nearly 3x the surface area of standard 90mm dishes, enabling higher dilution factors and improved colony separation for accurate enumeration.
Are these suitable for anaerobic cultivation?
Standard petri dishes can be used in anaerobic applications when placed in appropriate anaerobic chambers or jars with gas-generating systems.
What is the shelf life of sterile packaged dishes?
Consult product labeling for specific expiration dates. Store in clean, dry conditions away from direct sunlight to maintain sterility integrity.
Can the crystal-clear material interfere with fluorescence applications?
Polystyrene exhibits minimal autofluorescence and is compatible with most fluorescence microscopy applications when low-background observation is required.
