ConductScience 90mm 3-compartment petri dishes provide sterile polystyrene culture vessels optimized for multi-sample plating applications. Each dish features three discrete compartments within a standard 90mm diameter format, enabling simultaneous cultivation of multiple bacterial or fungal strains while maintaining sample isolation and reducing cross-contamination risk.
Manufactured from clear polystyrene with gamma sterilization, these dishes support routine microbiological workflows requiring parallel culture conditions. The compartmentalized design facilitates comparative studies, antibiotic sensitivity testing, and multi-strain isolation procedures commonly performed in clinical, research, and quality control laboratories.
How It Works
The 3-compartment design utilizes physical barriers within the petri dish to create three separate culture zones, each capable of supporting independent microbial growth. Each compartment maintains its own microenvironment while sharing the same atmospheric conditions within the closed dish system.
The polystyrene construction provides optical clarity for colony observation and enumeration while offering chemical resistance to standard culture media and sterilization protocols. The gamma-sterilized surface supports attachment and growth of most bacterial and fungal species commonly encountered in laboratory settings.

| Feature | This Product | Typical Alternative | Advantage |
|---|---|---|---|
| Compartment Design | Three discrete compartments in 90mm format | Single-well dishes require multiple units for parallel testing | Reduces incubator space requirements and ensures identical environmental conditions across samples |
| Sterilization Method | Gamma-sterilized polystyrene construction | Varies by manufacturer between gamma and ethylene oxide sterilization | Gamma sterilization leaves no chemical residues that could affect sensitive microbial cultures |
| Optical Clarity | Clear polystyrene for direct observation | Standard clear plastic construction across most manufacturers | Enables colony morphology assessment and photographic documentation without lid removal |
| Package Quantity | 100-count sterile packaging | Varies from 20-500 count packages depending on supplier | Balanced quantity for routine laboratory use without excessive inventory requirements |
This product provides compartmentalized culture capability within standard petri dish dimensions, offering space efficiency and consistent environmental conditions for multi-sample applications. The gamma-sterilized polystyrene construction supports routine microbiological workflows.
Practical Tips
Add media to compartments in sequence to minimize exposure time and contamination risk.
Why: Reduces the window for airborne contamination during dish preparation.
Store unused dishes in original packaging at room temperature away from direct light.
Why: Prevents degradation of polystyrene and maintains sterility integrity.
Label compartments clearly and maintain consistent inoculation volumes across experiments.
Why: Ensures reproducible growth conditions and accurate comparative results.
Always work within appropriate biosafety containment levels for cultured organisms.
Why: Prevents exposure to potentially pathogenic microorganisms during handling.
Allow agar to solidify completely before inoculation to prevent sample mixing between compartments.
Why: Ensures proper physical separation and prevents cross-contamination of test samples.
If condensation obscures observation, briefly invert dishes or adjust incubation humidity.
Why: Excessive moisture can interfere with colony counting and morphology assessment.

Compliance
What is the maximum volume capacity for each compartment?
Each compartment typically accommodates 3-5ml of culture medium, though exact volume depends on the specific application and desired agar depth.
Can these dishes be used for anaerobic culture?
Yes, when used within appropriate anaerobic systems or gas-generating envelopes that maintain oxygen-free conditions.
Are the compartments completely isolated from each other?
The compartments feature physical barriers that prevent liquid medium mixing but share the same atmospheric environment within the dish.
What sterilization method is used on these dishes?
Gamma irradiation sterilization is applied during manufacturing to ensure sterile surfaces ready for immediate use.
Can these be used with automated colony counters?
The standard 90mm format is compatible with most automated systems, though software may require configuration for compartmentalized counting.
What temperature range can these dishes withstand?
Polystyrene construction is suitable for standard incubation temperatures up to approximately 60°C, covering most routine culture applications.
