Watch Glass (150 mm) – Pack of 12

The 150 mm Watch Glass is a versatile piece of laboratory equipment used for large-scale evaporation, crystallization, or as a protective lid for wider glassware. Its gently concave shape facilitates even spreading of liquids and helps prevent spillage. Made from borosilicate glass, it can endure direct heating, sudden temperature changes, and exposure to corrosive substances. Ideal for use in advanced chemical synthesis, biology labs, or quality control settings. The wide surface is also helpful for placing solids to dry or for conducting qualitative observational studies. Supplied as a pack of 12, these watch glasses are reusable, easy to clean, and suitable for regular high-throughput use.
