Each petri dish includes a fitted lid to protect samples and maintain a clean environment, preserving experimental integrity and reducing contamination risk. Key benefits Clean, controlled conditions: fitted lids keep airborne contaminants out so cultures and samples stay reliable during incubation and handling. Durable, heat-resistant glass: made from glass that withstands high temperatures, providing reliable performance across a range of laboratory tasks. Ample working area: the plate size offers enough surface for tissue culture, agar work, and other scientific applications, making it a versatile option for many lab needs. Reinforced construction: thickened glass walls add strength for rigorous experiments and repeated use, increasing longevity compared with thinner alternatives. What makes this product stand out Glass construction resists scratching and chemical staining better than many plastics, helping preserve clarity for observation. Thickened design improves mechanical strength and durability for frequent handling and cleaning. Lidded configuration simplifies sample protection without additional accessories. Typical applications Cell and tissue culture: provides a stable, open surface for seeding and observing cells. Microbiology and mycology (agar plates): suitable for preparing agar plates for microbial growth and mushroom cultivation. Chemistry and heat-involved procedures: durable glass tolerates higher temperatures required by many laboratory protocols. Practical notes Each dish ships with a matching lid to help maintain sample integrity. Thickened glass construction supports repeated lab use and handling for consistent performance over time. This product is designed for laboratory and research use where a clean, durable, and reusable glass petri dish is required.
