Petri Dishes (Sterile Plastic) for Microbiology & Laboratory Use

Sterile Culture Dishes for Agar Plate Growth & Microbiological Testing

Sterile plastic Petri dishes are essential laboratory consumables for microbial culture, bacterial isolation, and surface testing in microbiology and laboratory environments. They provide a stable and controlled environment for agar-based culture, ensuring clear colony growth, reliable observation, and accurate microbiological analysis.

Hawach Petri dishes are manufactured from high-quality medical-grade polystyrene, offering high transparency, stable physical performance, and consistent results for routine laboratory workflows and microbiological applications.

What Are Petri Dishes Used For?

Petri dishes are widely used for microbial incubation and laboratory testing. They are commonly used together with cell spreaders and bacterial culture tubes in microbiology workflows.

They are one of the most widely used consumables for agar plate-based microbiology testing and analysis.

• Bacterial inoculation and streaking
• Microbial isolation and colony purification
• Surface and environmental microbial monitoring
• Antibiotic susceptibility testing and drug sensitivity assays
• Agar plate preparation and spreading workflows

FAQ

What are Petri dishes used for?

Petri dishes are used for microbial culture, colony isolation, and microbiological testing on agar surfaces. They are commonly used with cell spreaders for even sample distribution.

What material are Petri dishes made of?

Most disposable Petri dishes are made from polystyrene (PS), providing high clarity and reliable performance.

Are these Petri dishes sterile?

Yes. Hawach Petri dishes are EO sterilized, DNase/RNase-free, and non-pyrogenic for safe microbiological use.

What sizes are available?

Sizes range from 35 mm to 150 mm, with options including vented lids, counting grids, and compartment designs.

What is the difference between vented and non-vented Petri dishes?

Vented Petri dishes allow controlled gas exchange for aerobic cultures, while non-vented dishes provide a more sealed environment to reduce contamination and evaporation.
