Product Description
Divided petri dishes for parallel testing of a single sample using multiple agar media simultaneously. Available in 2, 3, and 4-compartment configurations in 90×15 mm format, manufactured from high-grade polystyrene with exceptional optical clarity for direct colony observation and heat resistance for use with hot agar pours.
The internal dividing walls create completely separate compartments within a single dish — allowing parallel culture of the same sample on different agars, side-by-side comparison of antimicrobial susceptibility, and multi-media screening in a single incubation step. This reduces the number of dishes, incubator space, and reagents required for multi-media testing workflows.
Supplied non-sterile and sleeve-packed. No external grip — smooth rim for consistent handling. If sterilization is required prior to use, UV or gamma irradiation are the recommended methods — do not autoclave polystyrene dishes.
Available Compartment Configurations:
2 Compartments
Two equal sections — ideal for dual-media comparison of a single sample
3 Compartments
Three equal sections — parallel testing on three different agars simultaneously
4 Compartments
Four quadrant sections — maximum parallel testing from a single sample
Key Features & Benefits
- Three compartment configurations — 2, 3, and 4-compartment formats for flexible parallel testing workflows
- Parallel multi-media testing — test a single sample on multiple agar types simultaneously in one dish, one incubation step
- Reduces material and space requirements — fewer dishes, less incubator space, and less agar required compared to running separate plates per medium
- 90 × 15 mm format — standard petri dish footprint for compatibility with existing incubator racks and colony counters
- Internal dividing walls — complete separation between compartments prevents cross-contamination between different agar media
- Exceptional optical clarity — high-grade polystyrene for clear, direct colony observation and comparison across compartments
- Heat resistant — withstands hot agar pours without deformation for reliable individual compartment filling
- No external grip — smooth rim profile for consistent, stable handling
- Non-sterile — supplied non-sterile; sterilize by UV or gamma irradiation prior to use if required — do not autoclave
- DNase/RNase, Human DNA, ATP, and Pyrogen-free — certified for sensitive microbiological applications

Storage & Handling
- Store in original sleeve packaging in a clean, dry environment away from direct sunlight and UV exposure
- Maintain storage temperature between 15°C and 30°C (59°F – 86°F)
- Keep away from excessive humidity
- If sterilization is required prior to use, UV or gamma irradiation are the recommended methods — do not autoclave polystyrene petri dishes
- Pour each compartment separately with the appropriate agar medium — allow one compartment to begin setting before filling adjacent compartments to prevent overflow across dividing walls
- Handle with gloves using standard aseptic technique inside a biosafety cabinet or laminar flow hood
- Dispose of used dishes in accordance with your institution's biosafety waste disposal guidelines
⚠️ Do not autoclave — polystyrene petri dishes are not autoclavable. When filling compartments, allow each agar pour to begin solidifying before filling adjacent compartments to prevent overflow across the dividing walls.
Frequently Asked Questions
What are divided petri dishes used for?
Divided petri dishes allow parallel testing of a single sample on multiple agar media simultaneously within one dish. Common applications include antimicrobial susceptibility testing, differential media comparisons, multi-selective media screening, and any workflow where you need to compare the same sample across different culture conditions in a single incubation step. They reduce the number of dishes, incubator space, and reagents required for multi-media testing.
Which compartment configuration should I use?
The 2-compartment dish is ideal for direct dual-media comparison — for example, selective vs non-selective media. The 3-compartment dish suits workflows requiring three media types simultaneously, such as identification panels. The 4-compartment (quadrant) dish maximizes parallel testing from a single sample and is commonly used for antimicrobial susceptibility screening and multi-media identification workflows.
How do I fill the compartments without overflow?
Pour each compartment separately and allow the agar to begin solidifying before filling adjacent compartments. This prevents hot liquid agar from flowing over the dividing walls into neighboring compartments. Work efficiently but carefully — pour each compartment at a slight angle to avoid air bubbles, and keep pours level to ensure even agar depth across the compartment.
Why do these dishes have no external grip?
The divided and RODAC dishes are supplied without an external grip rim. The smooth profile provides consistent handling and a lower profile that works well in incubator stacking configurations. Handle these dishes by the base and lid walls rather than a grip rim.
Are Certificates of Analysis available?
Yes — Certificates of Analysis (COA) are available upon request. Each lot is tested and certified RNase-, DNase-, Human DNA-, ATP-, and Pyrogen-free, manufactured under ISO 13485, and meets USP Class VI biocompatibility requirements. Contact us with your lot number for documentation.
