Plastic Petri Dishes, Plastic Petri Plates 60mm, 70mm, 90mm

Plastic petri dishes, available in multiple specifications (60/70/90mm), are circular vessels made of glass or plastic, used to hold liquid culture medium or solid agar culture medium for cell culture. A Petri dish consists of a base and a lid, and it is a chemical instrument used for bacterial culture, mainly made of glass or plastic.

Q: Are glass or plastic petri dishes better?

A: Plastic: Most plastic petris are thrown away after use, adding to plastic waste. Some eco-friendly options exist, but they are not as common. Glass: Glass Petri vessels can be used often, which is better for the environment. They are like eco-friendly heroes, fighting for both science and a cleaner planet.

Q: Can plastic petri dishes be reused?

A: It depends on whether you are talking about plastic or glass Petri dishes. Plastic dishes are never used more than once because they can’t be conveniently cleaned and sterilized a second time. Glass dishes can be used as long as they last, that is, until they break.

Q: How to sterilize plastic petri dishes at home?

A: You can sterilize plastic petri dishes at home by soaking them in a bleach solution or by using a pressure cooker with steam. For bleach sterilization, soak the dishes in a mixture of 1/4 cup bleach per liter of hot water for at least 12 hours, then rinse thoroughly and air-dry completely before use. For pressure cooker sterilization, place the dishes inside, add water to the bottom, and run it at 15 psi for 15-20 minutes at 121∘ after the initial 5-minute heating period; cool completely before opening.

Q: Are plastic petri dishes food safe?

A: These plastic petri dishes with overfit lids are injection-molded parts made from clear, high-quality, food-grade polystyrene.

Q: How to sanitize plastic dishes?

A: Immerse glass, porcelain, china, plastic dinnerware and enamelware for 10 minutes in a disinfecting solution of 2 tablespoons of chlorine bleach per gallon of hot water. Disinfect silverware, metal utensils, and pots and pans by boiling in water for 10 minutes.
