the amount of matter an object contains

These are very common in school laboratories. Their precision can vary from 1 g to 1 mg.

Almost museum pieces, but still common in some laboratories. They measure masses with good precision.

For containing volumes of liquids. The marking lines on the narrow neck indicate the precise volume on the flask.

Mainly for heating liquids. Its shape reduces losses from stirring or evaporation.

For dispensing and transferring known volumes of a liquid. It’s got a valve at one end for letting out precise volumes.

For measuring volumes very precisely. Put the level we want you to measure at eye level.

how much space an object it takes up

For collecting and measuring very small volumes of liquids. We use the wheel to suck the liquid into the pipette.

For measuring masses with great precision. It’s closed, so it avoids variation due to air drafts.

For containing or measuring volumes of liquid substances when we don’t need precision.
