Der Begriff Uhrglas leitet sich von früheren Taschenuhren ab, da diese meist ein gewölbtes Schutzglas hatten. Dem entsprechend sind Uhrgläser an den Aussenrändern leicht nach oben gewölbt, so dass eine flache Schale entsteht. Sie eignen sich für kleine Mengen von Flüssigkeiten, um diese Verdampfen zu lassen. Man kann Uhrgläser auch über dem Bunsenbrenner erhitzen, um das Verdampfen zu beschleunigen.
Durch ihre leicht gewölbte Form werden Sie im Labor auch zum Abdecken von Bechergläsern oder Petrischalen benutzt, zum Schutz vor Verunreinigung, vor Spritzern oder Verdunstung.
