Watch Glass (100 MM) – Pack of 12

The 100 mm Watch Glass is a shallow, curved piece of lab glassware used for various applications including evaporation, weighing solids, drying substances, and acting as a beaker lid to prevent contamination. Made from borosilicate glass, it resists thermal stress and chemical corrosion, ensuring long-lasting utility in demanding lab conditions. Its smooth, concave shape allows liquids to spread evenly for evaporation while preventing splashing. Commonly used in chemistry, biology, and environmental labs, this watch glass is also helpful for qualitative analysis and sample observation. The 12-piece pack is ideal for institutions managing multiple concurrent experiments or training sessions.
