A watch glass is a circular concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, for heating a small amount of substance, and as a cover for a beaker. When used to cover beakers, the purpose is generally to prevent dust or other particles from entering the beaker; the watch glass does ...
Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook ( colloq. lab notebook or lab book ) is a primary record of research . Researchers use a lab notebook to document their hypotheses , experiments and initial analysis or interpretation of these experiments.
Description: This book explained Dalton's theory of atoms and its applications to chemistry. Importance: The book was one of the first to describe a modern atomic theory, a theory that lies at the basis of modern chemistry. [3]: 251 It is the first to introduce a table of atomic and molecular weights.

[4] [5] These are the most universal character and are used for various purposes—from preparing solutions and decanting supernatant fluids to holding waste fluids prior to disposal to performing simple reactions. Low form beakers are likely to be used in some way when performing a chemical experiment.

The experiment became a popular way to illustrate the principles of air pressure, and many smaller copies of the hemispheres were made, and are used to this day in science classes. Reenactments of von Guericke's experiment of 1654 are performed in locations around the world by the Otto von Guericke Society.
