The 100mm watch glass is a compact yet essential tool for laboratories, refineries, and educational environments. Crafted from high-grade borosilicate glass, it offers excellent resistance to heat, thermal shock, and most chemicals—making it ideal for precision work in scientific and metallurgical settings.
Watch glasses serve a variety of purposes in the lab. With its smooth, slightly concave surface, the 100mm model is perfect for evaporating liquids, drying solid compounds, and covering small beakers or flasks to prevent dust, debris, or cross-contamination. Its smaller diameter makes it especially useful for handling small quantities or working in confined lab setups.
Thanks to its chemical resistance and thermal stability, this watch glass is suitable for applications involving gold and silver refining, sample testing, or student experiments. Whether you’re heating substances over a flame or using it to hold crystals or reagents, it performs safely and consistently.
