Petri dishes (90mm) supplied by IBEX SCIENCES are shallow, cylindrical containers used by scientists to grow and study micro-organisms like bacteria and fungi. They are a standard tool in school labs, hospitals, and universities across Pakistan. [1, 2, 3]
Product Overview
Key Technical Specifications
-
- Material: Made from clear, high-purity polystyrene (PS) plastic. This glass-like transparency allows easy viewing under a microscope. [1]
- Sterilization: Pre-sterilized using Ethylene Oxide (EO) gas or gamma radiation. This ensures they arrive completely free of any living germs. [1, 2, 3]
- Design: Built with flat bottoms for even distribution of growth agar. They include loose-fitting lids that let air circulate while blocking unwanted dust or contaminants. [1, 2, 3]
- Disposable: Being plastic, they are meant for single-use, preventing cross-contamination between different experiments. [1]
How to Use a 90mm Petri Dish
- Prepare Agar: Mix and heat your liquid nutrient agar gel.
- Pour Liquid: Working in a clean space, lift the lid slightly and pour the warm liquid agar into the bottom dish.
- Let it Cool: Put the lid back on fully. Wait until the liquid cools down and turns into a firm jelly.
- Add Bacteria: Use a sterile loop to spread your sample onto the jelly surface.
- Incubate: Turn the dish upside-down. Place it in a warm incubator to let the bacterial colonies grow. [1, 2]
