Know your glassware

When handling, measuring and heating liquids in the laboratory it is important to use the right sort of container. You need to choose a vessel of a suitable size for the required volume of liquid. Do not overfill a container, especially if you are going to heat it — the expanding liquid could overflow or boil over

Beakers are convenient for heating non-volatile liquids on a hotplate or using a Bunsen burner with a tripod and gauze. The contents can easily be stirred with a glass rod. The lip makes it easy to transfer liquids to other vessels. The graduations are only approximate, so beakers are unsuitable for measuring volumes
