Kelabscience Petri Dishes — Reliable Clarity for Every Culture

Kelabscience Petri Dishes are designed for accuracy, visibility, and contamination control in microbiological, pharmaceutical, and educational laboratories.
Available in glass (reusable) and medical-grade virgin polystyrene (single-use) versions, they combine optical clarity with practical handling features for consistent, reproducible results.
For standard agar plate preparation guidance, see Preparing Spread Plates – ASM Protocol 

Key Features

  • Material Options – Choose between borosilicate glass for repeated cleaning and heating, or medical-grade virgin PS for single-use sterility and convenience.

  • Optically Clear Surfaces – Smooth, transparent top and bottom surfaces allow precise colony observation and digital imaging.

  • Vented or Non-vented Lids – Three-vent design minimizes condensation and supports controlled gas exchange; non-vented lids help maintain humidity for longer incubations.

  • Stackable, Stable Structure – Flat bases and locating rings ensure vertical stacking without sliding, optimizing incubator space.

  • User-friendly Handling – Flared rims and squared edges make one-handed opening easy, even when wearing gloves.

  • Multiple Formats – Offered in round (35–150 mm) and square (100–150 mm) sizes for diverse microbiological and educational needs.

  • Clean Production & Secure Packaging – Each plastic dish is molded in a clean environment and securely packed; glass dishes are individually inspected for smooth edges and clarity.

FAQ

Q1: Are Kelabscience Petri Dishes suitable for cell or microbial culture work?
A: Kelabscience Petri Dishes are available in both glass (reusable) and medical-grade polystyrene (single-use) versions. The PS dishes are manufactured in clean conditions and supplied sterile, suitable for general microbiological and basic cell-handling use.

For more on agar plating methods, see Aseptic Laboratory Techniques (PMC) .

For specialized cell culture applications, we recommend surface-treated or TC-grade plates. Explore more options in our General Lab Plastics collection.

Q2: What is the difference between round and square Petri dishes?
A: Round dishes are standard for most microbiology and QC workflows, offering consistent agar spread and compatibility with common incubators. Square dishes provide a larger observation area and are preferred for imaging, environmental sampling, or custom assay layouts.

Q3: How should Petri dishes be stored before use?
A: Store in a dry, cool environment away from direct sunlight. Keep sleeves or boxes sealed until use to maintain cleanliness and sterility. Glass dishes should be cleaned and dried before reuse according to your lab SOP.
