Huanyu 120mm Glass Petri Dish with Lids - High Borosilicate Lab Dishes

In this review the Huanyu 120mm Glass Petri Dish with Lids is assessed for lab use, hobby microbiology and educational settings; the single biggest reason to buy is the durable high borosilicate glass construction that offers superior light transmission and chemical stability compared with plastic alternatives. The set of five 120mm bottom dishes and matching lids is best for anyone who needs clear, repeatable culture work and wants glassware that withstands high temperatures without warping.

Key Features

• Size and fit: A 120mm diameter bottom dish with a 132mm outer lid provides a generous working area suitable for standard agar plates and small-scale cultures.
• Durable material: Made from 2mm thick high borosilicate glass for higher strength and excellent light transmittance during inspection and photography.
• High temperature resistance: Rated for use up to 400 C with a low expansion rate, so dishes tolerate sterilization heat cycles well.
• Chemical stability: Acid and alkali resistance makes these dishes suitable when working with common lab reagents that would damage some plastics.
• Careful workmanship: Even, smooth edges and a flat bottom reduce contamination risk and make the dishes easier to clean and stack.
• Practical lid gap: A designed gap between bottom and lid helps with removal and covering while maintaining flatness for consistent incubation.

Who It's For

These glass petri dishes suit university labs, hobby microbiologists, and instructors who need reusable, heat-tolerant dishes for culture work or demonstrations. The clear glass helps when inspecting colonies and performing photographic documentation, while the chemical resistance supports a wider range of experiments than many plastic alternatives.

Those who require cold-storage compatible dishes should look elsewhere, because these dishes are not rated for freezing temperatures. Also, users seeking single-use convenience or extremely lightweight options may prefer disposable plastic plates.

Pros & Cons

Pros

• High borosilicate glass provides strong, clear optics and better long-term durability than typical plastics.
• Good thermal performance up to 400 C, suitable for many sterilization processes.
• Chemically stable against acids and alkalis, expanding possible lab applications.
• Well finished edges and a flat base reduce handling issues and improve cleanliness.

Cons

• The lids are intentionally slightly larger than the bottoms and there is a visible gap, which some users may find odd though it aids removal.
• Not suitable for low-temperature storage or freezing, limiting some workflows.

Our Verdict

The Huanyu 120mm Glass Petri Dish set is a solid, cost-effective choice for labs and educators who need reusable, heat-resistant dishes with good optical clarity and chemical stability. It delivers clear value where durability and thermal performance matter, but it is not suitable for freezing or one-time disposable workflows.

Frequently Asked Questions

Are these dishes reusable?
Yes. The high borosilicate glass and smooth finish make them suitable for repeated cleaning and sterilization cycles.

Can these be frozen for cold storage?
No. These dishes are not resistant to low temperatures and should not be frozen.

Do the lids seal tightly?
The lids are slightly larger with a designed gap to ensure flatness and easy removal; this is normal and does not affect typical incubation use.
