Sterile 90mm Petri Dishes with Vented Lids — 30-Pack Polystyrene

Product description

Absolute sterility and trace safety: Each 90 mm dish is ethylene oxide (EO) sterilized and handled in a 10,000-grade cleanroom environment. They are guaranteed DNase/RNase-free and pyrogen-free, reducing the risk of enzymatic or endotoxin contamination for delicate culture work.

Laboratory-grade construction: Manufactured from heavy-duty polystyrene with high optical clarity, these plates have a reinforced body and a flat, uniform bottom to support even agar surfaces and clear visual inspection under magnification.

Engineered vented lids: The included lids incorporate vents to improve gas exchange and airflow, helping cultures breathe while limiting moisture accumulation on the lid surface. This design is intended to support bacteria, fungi, yeast, mold, and other microbial culture needs.

Dimensions and pack size: Each plate measures 90 mm in diameter and 15 mm in depth, a compact standard suitable for many laboratory assays, seed or tissue work, and STEM projects. The set contains 30 individual petri dishes with matching lids, providing a practical supply for multi-step experiments or teaching sessions.

Wide range of uses: Appropriate for professional researchers, educators, and at-home hobbyists working with agar media, sample storage, colony isolation, or microscopy prep. These disposable plates simplify cleanup and reduce cross-run contamination when used as directed.

Pros

  • EO-sterilized in a 10,000-grade cleanroom
  • Thick, clear polystyrene with flat bottoms
  • Vented lids that reduce condensation and aid gas exchange

Cons

  • Lids may fit loosely on some units
  • Occasional damaged piece possible in transit
  • Designed as disposable; not suitable for autoclave reuse

VerdictThese 90 × 15 mm polystyrene culture plates provide a reliable, sterile option for labs, classrooms, and hobbyists. The thick, ultra-clear material and flat bottoms make microscopic observation easy, while the vented lids balance gas exchange and condensation control. Packaged in a 30-count set and processed in a controlled cleanroom with EO sterilization, they’re a convenient disposable choice fo

Reviews

  1. Noe A. Rios 4/5

    Caps feel loose on some sets

    Good quantity for the pack, but a few lids don’t snap down tightly and can pop off more easily than expected.

  2. johnny 3/5

    Mixed experience — one arrived damaged

    Plates are generally fine, but lids appear oversized and one plate in the sealed bundle was cracked. Probably won’t reorder.

  3. God Emperor 4/5

    Solid starter pack for hobby cultivators

    Useful for home agar work and expanding multiple strains. Arrived sterile and clear, suitable for pours and incubation.

  4. Zakk Comfort 5/5

    Disposable plates that perform

    Did exactly what disposable dishes should do. No contamination showed up during my runs.

  5. Myco mike 5/5

    Ideal for mycology pours

    Sturdy plates that handled pour-overs perfectly. Stayed intact without pressure-cooking and produced clean, reliable pours.
