Petri dishes

Introduction to Petri dishes

A petri dish is a shallow, lidded laboratory vessel commonly used to hold culture media for microorganisms, observe samples, and conduct ecological or biological experiments. Depending on aseptic requirements and experimental frequency, users can choose reusable glass petri dishes or disposable plastic petri dishes.

When selecting Petri dishes, key criteria include material (soda-lime glass, molded glass, or plastic), venting features (with 3 vents or non-vented), sterility status, and design (standard round, bi-plate/2-compartment, 120x120mm square, grid-marked, or 96-well U-bottom, V-bottom, or flat-bottom sampling plates). Hoa Viet currently supplies Petri dishes from manufacturers including Aptaca (Italy), Assistent (Germany), Duran (Germany), and Jet Biofil (China), offering a wide range of sizes from 4cm to 140mm in diameter.

Which manufacturers' petri dishes does Hoa Viet supply?

Currently, Hoa Viet distributes glass and plastic petri dishes from brands including Aptaca (Italy), Assistent (Germany), Duran (Germany), and Jet Biofil (China). Customers can contact Hoa Viet for detailed technical advice for each application.

What is the difference between plastic petri dishes with 3 vents and those without vents?

Dishes with 3 vents create a small gap between the lid and base, facilitating air exchange for aerobic microorganisms and minimizing condensation on the lid. Conversely, non-vented dishes fit tighter, helping to limit moisture loss from culture media.

What sterility standards do Jet Biofil sterile plastic petri dishes meet?

The product is sterilized by irradiation to a sterility assurance level of SAL 10⁻⁶. The dishes are also certified DNase-free, RNase-free, and non-pyrogenic, suitable for microbiological and molecular biology testing.

When should glass petri dishes be chosen over plastic petri dishes?

Glass petri dishes (such as soda-lime or pressed glass) are suitable when laboratories need to wash and reuse them multiple times to reduce long-term consumable costs. Meanwhile, sterile disposable plastic petri dishes are ideal for procedures requiring high convenience and minimal risk of cross-contamination.
