Laboratory equipment used for holding liquids is utilized when working in a laboratory either in school or professionally. The purpose of using laboratory equipment is to safely and accurately perform experiments or take measurements. Using the proper laboratory equipment for their intended purpose is essential when conducting experiments for your safety and the safety of others.
Beakers come in different sizes and are usually cylindrical with a spout for pouring liquids. They are specifically used to hold, mix, stir and heat liquids.
Bottles usually have a straight neck and can be used for storing, mixing and for displaying liquids. Some glass bottles used for storing liquids are amber in color to prevent light from affecting its contents. Like beakers, bottles come in different shapes and sizes and can be used with a stopper.

A thermometer is used to measure the temperature of liquids as well as other compounds. Thermometers are marked with a calibrated scale to be able to determine the temperature taken.
Pipettes Burettes and Funnels
A pipette, also known as a chemical dropper, is a glass or plastic tube used to suction small amounts of liquid to enable to transfer the liquid from one place another. They come in different types, each used for a specific purpose either for laboratory experiments or medical tests.
A burette is cylindrical equipment made of glass with a stopcock at the bottom. It is used in experiments to accurately measure small quantities of liquid.
A funnel is a laboratory instrument used to pour liquids into another container without the risk of spilling the liquid. This is made possible by the funnel’s shape, which includes a wide mouth and a narrow tube. The tube can be inserted into the container where the liquid will be poured into.
Evaporating dishes are usually made of glazed porcelain and are used to heat and evaporate liquids under high heat. Some evaporating dishes have a spout for pouring liquids.
A round-bottom flask, also known as round-bottomed flask or Erlenmeyer Bulb, is used for heating or boiling liquids evenly. They have a cone shaped neck with a spherical bottom and are mainly used in distillation experiments.
A volumetric flask is made of glass or plastic and is used for volumetric analysis and to prepare solutions. They have a long neck, a flat bottomed bulb and usually used with a stopper. Like bottles, they are sometimes amber in color to prevent light from affecting the contents.
An Erlenmeyer flask, also known as a conical flask or E-flask, is a container used to heat and store liquids. It has a flat base, a cone-shaped body, and a cylindrical neck, thereby heating faster because of its wider surface. Additionally, its shape allows it to be used with a stopper, to be stirred during an experiment, keeps it from falling over and keeps liquid from spilling.
A stir rod is usually made of glass to be able to withstand high temperatures and is used to mix chemicals and liquids.
