| Automation Level | manual |
100mm sterile petri dishes manufactured from crystal-clear polystyrene provide optimal visibility for microbial culture observation and colony counting. The 100mm diameter represents the standard format for agar plate preparation, fitting conventional incubators and laboratory workflows. Sterile packaging ensures immediate use without contamination risk.
The transparent polystyrene construction enables clear visualization of bacterial and fungal growth patterns while maintaining structural integrity under standard incubation conditions. These dishes support routine microbiological procedures including streak plating, dilution series, and antimicrobial susceptibility testing protocols.
How It Works
Petri dishes function as sterile containers that maintain controlled environmental conditions for microbial growth on solid media. The shallow, wide design maximizes surface area while minimizing media depth, promoting uniform oxygen distribution and facilitating colony observation. The overlapping lid creates a protected microenvironment that prevents airborne contamination while allowing gas exchange.
The crystal-clear polystyrene material provides optical clarity for colony morphology assessment and accurate enumeration. The 100mm diameter accommodates standard volumes of molten agar (15-25 mL) while fitting conventional laboratory incubators, shakers, and microscope stages. The sterile packaging maintains aseptic conditions until opening, eliminating the need for pre-sterilization protocols.

Comparison Guide
| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Material Clarity | Crystal-clear polystyrene construction | Standard plastic dishes may have optical distortions | Enhanced visualization enables accurate colony morphology assessment and precise enumeration |
| Sterility Assurance | Pre-sterilized packaging | Some products require user sterilization | Eliminates contamination risk and reduces preparation time in busy laboratories |
| Size Standard | 100mm standard diameter | Alternative sizes may require different protocols | Universal compatibility with existing laboratory equipment and established methods |
| Lid Design | Overlapping lid with controlled ventilation | Tight-sealing designs may limit gas exchange | Balances contamination protection with essential oxygen availability for aerobic growth |
These petri dishes provide standard 100mm format with crystal-clear visibility and pre-sterilized convenience. The polystyrene construction and overlapping lid design support routine microbiological workflows while maintaining optical clarity for accurate observations.
Practical Tips
Pour agar at 45-50°C to prevent thermal shock while ensuring proper flow and leveling.
Why: Optimal temperature prevents dish warping while creating uniform media thickness.
Allow agar plates to dry for 15-30 minutes before inoculation to prevent spreading of sample.
Why: Surface moisture can cause sample to spread uncontrollably across the agar surface.
Store unused sterile dishes in original packaging away from direct sunlight and humidity.
Why: UV exposure and moisture can compromise packaging integrity and sterility assurance.
Dispose of used dishes according to biohazard waste protocols after appropriate decontamination.
Why: Cultured organisms present potential infectious hazards requiring proper waste management.
If condensation forms on lid during incubation, briefly invert dishes or use incubators with humidity control.
Why: Excessive moisture can interfere with colony morphology and enumeration accuracy.
Label the bottom of dishes rather than lids to prevent sample mix-ups during handling.
Why: Lids can be easily switched between dishes, leading to sample identification errors.

Compliance
What agar volume should be used with 100mm dishes?
15-25 mL of molten agar creates an optimal 4mm depth that supports proper growth while allowing clear colony visualization and easy isolation.
Are these dishes compatible with anaerobic culture methods?
Yes, the tight-fitting lid design supports anaerobic jar systems and gas-pak methods when used with appropriate anaerobic indicators.
What temperature range can these dishes withstand?
Consult product datasheet for specific temperature tolerances. Standard polystyrene dishes typically support routine incubation temperatures.
Can these be used for cell culture applications?
These dishes are optimized for microbial culture on agar media. For mammalian cell culture, tissue culture-treated surfaces are recommended.
How should unused sterile dishes be stored?
Store in original packaging in clean, dry conditions away from direct sunlight to maintain sterility until use.
Are the dishes compatible with automated colony counters?
Yes, the 100mm diameter and clear bottom design are standard formats compatible with most automated counting systems.
