Product Details

Commonly used as covers for beakers, with fire-polished edges to prevent chipping. Flinn only carries watch glasses that are made of borosilicate glass, so these can even be gently heated in a burner flame to dry precipitates or evaporate solutions to dryness. Non-borosilicate watch glasses will shatter when heated and are a potential safety risk.
