Product Overview
The Borosilicate Glass Petri Dish 90mm is engineered for precision and durability in laboratory environments. Constructed from high-grade borosilicate glass 3.3, this dish offers exceptional thermal resistance, withstanding temperatures up to 500°C without compromising structural integrity. Its optical clarity ensures accurate visualization of microbial colonies, cell cultures, or sample observations under microscopes. The 90mm diameter provides ample surface area for uniform media distribution, reducing edge effects that can skew results. Unlike plastic alternatives, this glass variant eliminates static charge buildup, minimizing contamination risks during sensitive procedures. The dish’s low thermal expansion coefficient prevents cracking during autoclaving, making it reusable and cost-effective for high-throughput labs. Each dish undergoes rigorous quality checks to ensure consistent wall thickness and flatness, critical for reliable experimental reproducibility. The laboratory-grade certification guarantees compliance with ISO standards for biological testing. Whether used for bacterial streaking, fungal sporulation, or eukaryotic cell adhesion studies, this petri dish maintains performance across diverse protocols. Its chemical inertness resists reactions with acids, alkalis, or solvents, preserving sample purity. The pack of 20 ensures sufficient quantity for batch experiments while optimizing storage space. Designed for professionals, this dish combines functionality with longevity, reducing the need for frequent replacements and supporting sustainable lab practices.
FAQs
1. Can this petri dish be used for plant tissue culture applications?
The borosilicate glass composition is chemically inert and suitable for plant tissue culture, though you may need to verify compatibility with specific agar or gel media formulations used in your protocol.
2. How does the heat resistance compare to soda-lime glass petri dishes?
Borosilicate glass 3.3 can withstand sudden temperature changes up to 500°C, whereas soda-lime glass typically cracks at 200-250°C, making this variant far superior for autoclaving and high-temperature applications.
3. What’s the typical lead time for bulk orders of 500+ units?
Lead times for bulk orders depend on current inventory levels, but standard processing ranges between 10-15 business days for quantities above 500 units, excluding transit time.
4. Are these dishes compatible with automated colony counters?
Yes, the uniform 90mm diameter and optical clarity are designed to work seamlessly with most automated colony counters, though you should confirm the device’s minimum dish thickness requirements.
5. How should these dishes be stored to prevent contamination before use?
Store in their original packaging within a dust-free cabinet at room temperature; avoid exposure to direct sunlight or humidity, and use within 12 months of purchase for optimal sterility.
