| Automation Level | manual |
35mm sterile petri dishes manufactured from crystal-clear polystyrene provide a reliable culture vessel for microbiological applications requiring smaller sample volumes or space-constrained incubation. The dishes feature a vented stackable lid design that allows controlled gas exchange while maintaining sterile conditions during culture growth periods. Each dish is gamma-sterilized and certified non-pyrogenic, eliminating endotoxin contamination that could interfere with cell culture or microbial growth studies.
The transparent polystyrene construction enables clear visualization of colony morphology, growth patterns, and culture characteristics under standard laboratory microscopy. The stackable design optimizes incubator space utilization while the vented lid system provides consistent atmospheric exchange required for aerobic culture conditions.
How It Works
Petri dishes function as contained culture environments that provide a controlled interface between growth media and the surrounding atmosphere. The polystyrene construction offers optical clarity for transmitted and reflected light microscopy while maintaining chemical inertness that prevents interaction with culture media components.
The vented lid design incorporates precise apertures that allow controlled gas exchange, enabling aerobic metabolism while preventing contamination from airborne particles and microorganisms. The stackable architecture creates a stable vertical configuration that maximizes incubator space utilization during extended culture periods. Gamma sterilization ensures sterility assurance level of 10^-6 while non-pyrogenic certification confirms the absence of endotoxin contamination that could affect cell viability or microbial growth responses.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Material Construction | Crystal-clear polystyrene with gamma sterilization | Standard polystyrene or glass construction with varying optical clarity | Ensures consistent microscopic visualization and eliminates autoclaving requirements |
| Lid Ventilation System | Vented stackable lid design | Standard flat lids with limited gas exchange | Provides controlled atmospheric exchange while maintaining contamination protection |
| Sterility Assurance | Non-pyrogenic certification with gamma sterilization | Basic sterilization without endotoxin testing | Eliminates endotoxin interference in sensitive culture applications |
| Size Format | 35mm diameter optimized for small volumes | Standard 60-100mm formats requiring larger media volumes | Reduces media consumption and incubator space requirements for small-scale work |
These dishes combine crystal-clear polystyrene construction with vented lid design and non-pyrogenic certification to provide reliable culture vessels for small-volume applications. The 35mm format optimizes space utilization while maintaining optical clarity for microscopic examination.
Practical Tips
Pre-warm dishes to room temperature before adding hot media to prevent thermal shock and condensation formation.
Why: Prevents stress cracking and maintains optical clarity for observation.
Store unused dishes in original packaging until needed to maintain sterility and prevent dust accumulation.
Why: Preserves sterility assurance and optical properties.
Label dishes on the bottom edge rather than the lid to prevent label loss during handling.
Why: Ensures sample identification throughout the culture period.
Handle dishes by the edges to avoid fingerprint contamination on viewing surfaces.
Why: Maintains optical clarity for microscopic examination and documentation.
Allow dishes to reach incubator temperature before inoculation to prevent condensation formation.
Why: Eliminates water droplets that can interfere with colony counting and observation.
Stack no more than 10-12 dishes to prevent excessive weight on bottom dishes during incubation.
Why: Prevents deformation that could affect media distribution and gas exchange.

Compliance
What is the recommended media volume for 35mm dishes?
Approximately 5-8ml provides optimal coverage and depth for most culture applications while allowing proper gas exchange.
Are these dishes suitable for anaerobic culture conditions?
The vented lid design is optimized for aerobic conditions; anaerobic applications require additional sealing or anaerobic chamber systems.
What temperature range can these dishes withstand?
Polystyrene construction is suitable for standard incubation temperatures up to 65°C; consult product datasheet for specific thermal specifications.
How should unused dishes be stored to maintain sterility?
Store in original packaging in a clean, dry environment away from direct sunlight and temperature extremes.
Are these dishes compatible with automated colony counters?
The crystal-clear construction and standard 35mm format are compatible with most automated counting systems requiring optical clarity.
What is the shelf life of sterile dishes?
Gamma-sterilized dishes maintain sterility when stored properly; consult packaging for specific expiration dating.
Can these dishes be autoclaved for reuse?
These are single-use sterile dishes; polystyrene construction is not designed for autoclave sterilization cycles.
