MEDILAB Petri Dishes are high-quality, reusable culture dishes made from Borosilicate Glass 3.3, engineered for precise microbiological, analytical, and research applications. They provide a sterile, stable, and chemically inert surface for growing, observing, and analysing microorganisms, tissue cultures, and small-scale biological samples. Their durability and clarity make them essential tools for research laboratories, pharmaceutical testing, industrial QC/QA environments, and academic institutions.

 Key Features

• High-clarity borosilicate glass ensures excellent visibility for colony observation and documentation.
• Thermally stable construction suitable for autoclaving, dry heat sterilisation, and repeated laboratory use.
• Chemically inert and contamination-resistant, making it ideal for sensitive microbial work.
• Uniform wall thickness for consistent performance, temperature resistance, and mechanical strength.
• Reusable and eco-friendly, reducing disposable plastic waste.
• Smooth surface finish allows even distribution of culture media.
• Stackable design for easy storage and incubation handling.
• Flat-lid / grip-lid options (based on customer requirement) for controlled gas exchange.

Handling & Precautions

Before Use:

• Ensure petri dishes are properly cleaned and sterilised.
• Avoid sudden temperature changes to prevent thermal shock.

During Use:

• Handle with gloves to maintain sterile conditions.
• Keep the lid slightly ajar during inoculation to minimise contamination.
• Do not expose to open flame directly.

• Cleaning & Sterilisation:

• Wash gently using mild detergents; avoid abrasive scrubbing.
• Rinse with distilled water for microbiological work.
• Autoclave at recommended temperature/time only.

Best Practices:

• Store in a dry, dust-free environment.
• Inspect for cracks or chips before each use.
• Avoid stacking too high to prevent damage.
