Plastic petri dishes

Introduction to Plastic Petri Dishes

Plastic Petri dishes are shallow, lidded laboratory dishes widely used for microorganism cultivation, colony isolation, and sample observation. As single-use disposables, they minimize the risk of cross-contamination between analytical batches and eliminate tedious washing and drying steps.

When choosing plastic Petri dishes, users should consider criteria such as sterility status, thickness, vented (3 vents) or non-vented designs, and standard or 2-compartment formats. Available standard sizes include diameters of 90mm, 140mm, or square 120x120mm. Hoa Viet currently distributes plastic Petri dishes from manufacturers Aptaca (Italy) and Jet Biofil (China), meeting the demands of microbiology testing and cleanroom applications.

How do plastic Petri dishes with 3 vents differ from non-vented dishes?

Vents on the lid provide small gaps that support gas exchange for aerobic microorganisms and help reduce condensation inside the dish. Non-vented dishes are typically preferred when media evaporation needs to be minimized or during anaerobic cultivation procedures.

Which sterility standards do Jet Biofil sterile plastic Petri dishes meet?

Jet Biofil sterile plastic Petri dishes are treated by irradiation to achieve a sterility assurance level (SAL) of 10⁻⁶. The products are certified DNase-free, RNase-free, and non-pyrogenic.

When should 2-compartment or square 120x120mm plastic Petri dishes be used?

Two-compartment Petri dishes allow pouring two different agar media into a single dish for parallel observation and incubator space saving. Meanwhile, square dishes 120x120mm provide a large culture surface, suitable for high-density spread plating or quantitative spot inoculation.
