• Borosilicate glass supports use with common laboratory chemicals
• 50mm diameter fits standard classroom lab activities
• Concave shape helps contain liquids during observation
• Fire-polished edges reduce sharp handling surfaces
• Pack of 10 supports group experiments or shared lab use

These borosilicate cover glasses are designed for classroom and laboratory activities involving specimen observation, evaporation studies, and small-scale material handling. The concave form supports demonstrations where liquids or samples need to be contained and observed without spillage. Commonly used in chemistry and biology instruction, cover glasses help students practice careful handling of fragile labware while reinforcing proper microscopy and experimental techniques.
