Watch Glass 120mm – Versatile Borosilicate Glass for Laboratory Use
The 120mm watch glass is a versatile and widely used tool in laboratories, refineries, and academic settings. Made from high-quality borosilicate glass, it delivers excellent resistance to heat, thermal shock, and most laboratory chemicals—ensuring long-lasting and safe performance.
This size offers a perfect balance between surface area and maneuverability, making it ideal for evaporation, drying of chemical solids, and covering medium-sized beakers or containers. Its slightly concave design prevents spillage and supports even drying, while its transparency allows you to monitor your samples without interference.
Whether you’re working in a gold refining facility, conducting metallurgical testing, or managing a chemistry lab, this 120mm watch glass provides consistent results under various thermal and chemical conditions. It’s also reusable, easy to clean, and suitable for both professional and educational use.
