About Petri Dish 90mm

Specification

A 90 mm Petri dish (also written as Petri plate) is a standard laboratory dish used for culturing microorganisms, cells, or small organisms.

• Diameter: 90 mm (standard size; sometimes measured as 8690 mm depending on manufacturer)

• Height: 1520 mm

• Material:

  • Polystyrene (disposable, usually sterile)

  • Plastic (reusable, autoclavable)

• Type:

• Vented (with small air exchange gaps in the lid) for aerobic cultures

• Non-vented for reduced evaporation or anaerobic work

• 
  
• Typical Uses

• • Growing bacteria or fungi on agar media (e.g., LB agar, nutrient agar)

  • Tissue culture (with treated plastic)

  • Antibiotic sensitivity testing (Kirby-Bauer disc diffusion)

  • Environmental sampling



Robust and Reliable Design

Made from premium-grade plastic, this Petri Dish offers clarity and strength. It is perfectly suited for laboratory culture work, enabling easy observation of specimens and minimizing breakage risks that are common with glassware alternatives. Its round shape and standardized size make it compatible with most laboratory protocols.


Versatile Laboratory Applications

These Petri Dishes are indispensable in microbiological, clinical, or environmental laboratories. They provide the ideal environment for growing, observing, or transporting samples. Whether for educational use or professional research, their design ensures reproducibility and consistent results across varied settings.



FAQs of Petri Dish 90mm:




Q: How do you use the 90mm plastic Petri Dish in laboratory applications?

A: To use the 90mm Petri Dish, sterilize it if necessary, pour your prepared medium into the dish, and allow it to solidify. Once ready, you can inoculate your sample. The transparent plastic enables easy monitoring of specimen growth during incubation.



Q: What are the benefits of using a plastic Petri Dish over a glass one?

A: Plastic Petri Dishes are lightweight and shatter-resistant, making them safer and easier to handle. They are also cost-effective, disposable, and minimize contamination risks compared to cleaning reusable glass dishes.



Q: When should the Petri Dish be replaced during laboratory use?

A: Replace the Petri Dish after each experiment or if contamination is observed. Single-use plastic dishes are recommended for maintaining sterile conditions and preventing cross-contamination between experiments.



Q: Where can you purchase this Petri Dish in India?

A: These Petri Dishes are available through reputable manufacturers, exporters, importers, and suppliers across India. You can contact specialized laboratory equipment traders for bulk orders or specific requirements.



Q: What is the process for preparing samples in the 90mm Petri Dish?

A: Begin by sterilizing the dish (if required), adding your agar or growth medium, and allowing it to set. Next, inoculate your sample onto the mediums surface and incubate under appropriate conditions for observation.



Q: Can these Petri Dishes be used for educational laboratory projects?

A: Absolutely. The 90mm plastic Petri Dish is ideal for student laboratories due to its safety features, transparency, and ease of disposal after use. They are frequently used in school and college experiments involving microbiology or cell culture.
