Corning Petri Dish 100 mm Polystyrene Sealed Package 500 Dishes

Description

Corning® 100 mm x 15 mm Clear Flat-Bottom Polystyrene Petri Dishes, Sterile (430167) – Case of 500

The Corning® 430167 is a foundational, research-grade laboratory consumable engineered for general microbiology workflows, cell culture staging, crystallization assays, and sample isolation. Precision-molded from high-purity, premium virgin polystyrene, these dishes feature a standard 100 mm nominal outer diameter with a flat-bottom base that ensures high optical clarity and uniform agar depth distribution. Unlike tissue culture-treated plates, these dishes feature a natural, **non-treated hydrophobic plastic surface** designed to prevent cell attachment, making them ideal for microbial colony growth and suspension processing. Supplied as a high-density commercial facility case of 500 dishes (organized in convenient, sterile sleeves of 20), this single-use model features an engineered vented lid to support stable gas exchange and temperature equilibration during incubator storage.

Technical Performance & Design Architecture

• Optically Clear Non-Treated Surface: Injection-molded from specialized crystal-grade polystyrene under Class 100,000 cleanroom conditions. The surface remains unmodified (non-TC treated), providing a pristine, hydrophobic substrate for pouring agar plates or cultivating non-adherent organisms.
• Engineered Vented Gas Exchange Lid: The matching lid is constructed with integrated, microscopic venting ridges. These vents permit continuous, balanced gas exchange and aerobic respiration while minimizing condensation buildup on the top inner wall, preventing droplet fall back onto the agar matrix.
• Squared Stack-Ring Base Stabilization: Features an integrated structural stacking ring molded onto the perimeter of the lid. This mechanical lip locks stacked dishes securely together, preventing sliding, shifting, or accidental tipping when transferring dense rows of plates from preparation benches to standard incubators.
• Sleeve-Packed Aseptic Security: Packaged in durable, heavy-gauge polymer sleeves containing 20 dishes each. This inner configuration allows facility managers to open a localized bundle for benchtop use while preserving the sterile barrier of the remaining backup stock.

Key Benefits & Applications

• Routine Microbial Colony Isolation: The industry-standard vessel for pouring agar slants, striking bacterial strains, isolating fungal cultures, and running anti-microbial disk diffusion panels.
• Suspension Cell Line Handling: Provides a completely inert, non-binding plastic matrix for scaling up non-adherent mammalian cell lines, hybridomas, or embryoid bodies without unintended surface grounding.
• Organism Harvesting and Micro-Dissection: Serves as an ideal, low-friction container for tissue micro-dissection, mouse organ harvesting loops, or temporary sample containment beneath stereo stereomicroscopes.
• **cgmp Lot-Specific Quality Control:** Every logistics shipping container is printed with a dedicated manufacturing lot code, ensuring complete trace verification during standard facility audits.

Corning® is a registered commercial trademark of Corning, Inc. Catalog number 430167 specifies the non-treated 100 mm x 15 mm polystyrene Petri dish. For applications requiring cell attachment, tissue culture expansion, or surface anchorage, companion tissue culture-treated (TC) culture dishes (such as Corning SKU 430165) must be integrated into the procurement loop instead.
