Plastic Petri Dishes
Free!
A Plastic Petri Dish is a clear, disposable culture vessel used to grow and isolate microorganisms on agar or to handle small samples in the lab. It’s lightweight, stackable, and supplied sterile with vented lids for airflow. Buyers choose it for consistent clarity, easy handling, and contamination control across research, education, food testing, and clinical labs. Options include bacteriological or tissue-culture surfaces and multiple diameters.
Description
Plastic Petri Dishes are clear, shallow culture vessels used for growing and isolating microorganisms, culturing cells on treated surfaces, and handling small samples. Molded from lab-grade polystyrene for optical clarity, they are typically supplied sterile and ready for plating. A low-profile base, smooth interior, and precisely matched lid promote even agar distribution and reliable colony growth. Stackable rims and vented lid options support airflow and efficient incubator use in busy labs.
Key features and benefits:
• Crystal-clear walls for easy colony counting and imaging
• Sterile, ready-to-use packaging; options labeled DNase/RNase-free and non-pyrogenic
• Vented and non-vented lids to balance gas exchange and evaporation control
• Stackable ring design for stable incubator stacking and safe transport
• Smooth, flat base for uniform agar thickness and consistent results
• Bacteriological (non-treated) or tissue-culture treated surfaces to match application
• Available in popular diameters (e.g., 35, 60, 90, 150 mm) and compartment styles (single or divided)
• Slip-resistant edges and easy-grip lids that speed up gloved handling
Typical applications:
• Environmental monitoring and surface swabs
• Microbial plating, isolation streaks, and antibiotic susceptibility testing
• Food, beverage, and water-quality labs
• Clinical and pharmaceutical QC
• Teaching labs and basic research workflows
Comparison and selection notes:
• Versus glass dishes: plastic is lightweight, shatter-safe, and consistent batch to batch; glass suits repeated sterilization and high-heat use
• Versus multiwall plates: Petri dishes provide larger, open surfaces ideal for colony work and diffusion tests
• Choose vented lids for aerobic cultures; non-vented to reduce evaporation during longer incubations
Quality and compliance considerations:
• Look for products manufactured under a recognized medical or laboratory quality system (such as ISO 13485 or ISO 9001) with lot traceability
• Prefer sterilization validated to accepted standards, with certificates of irradiation and bioburden control available on request
