ULTECHNOVO 2-Pack Glass Sheets for Flame Test, 1.96" Square Laboratory Optical Filter for Chemistry Experiments, High-Temperature Observation Lens for Industrial Furnace & Science Class

• ESSENTIAL OPTICAL FILTER FOR IDENTIFICATION: The precision of chemistry flame tests with our cobalt glass sheets; specifically designed to filter out dominant yellow sodium flares, these 1.96-inch lenses allow the distinct pale violet light of compounds to be observed clearly, making them indispensable for accurate element identification in laboratory settings
• COBALT-INFUSED GLASS COMPOSITION: Crafted through a professional process incorporating cobalt metaaluminate (Co(AlO2)2), our laboratory glassware provides consistent optical properties and performance; each 5.00x5.00x0.50cm square is built to withstand the rigorous heat of Bunsen burners and industrial environments, ensuring a tool for your scientific supplies
• VERSATILE INDUSTRIAL & CLASSROOM APPLICATION: Beyond the chemistry lab, this cobalt glass serves as a professional observation lens for cement production, steel plants, and high-temperature furnace monitoring; it is the ideal demonstration tool for physics optics experiments and classroom science projects, providing students with a clear view of light filtration principles
• PERFORMANCE FOR SCIENTIFIC OBSERVATION: Each set includes two authentic cobalt plates weighing approximately 1.48 ounces, offering a compact and manageable size for both handheld use and fixed-mount experimental devices; the vibrant color maximum yellow-light suppression, providing crisp and precise visual data for forensics, identification, and material testing
• PROFESSIONAL GRADE WITH SAFETY GUIDANCE: As a dedicated laboratory experiment device, this glass is optimized for functional purity and heat resistance; please note that due to its industrial-grade technical application, edges are unpolished for maximum utility, we recommend handling with protective gloves or using lab clamps during experiments to a safe and successful discovery process
