2.2.1 Where an approximate volume is required
Where accuracy is not essential you will generally use a measuring cylinder (Figure 3), having a volume scale etched into the glass, or a dispenser (Figure 4). The latter fits onto a container of liquid and is used for the repeated delivery of known volumes.
In addition, the humble Pasteur pipette (Figure 5) is probably one of the most commonly used items in the laboratory. These are used for the transfer of liquids (often dropwise) where accuracy is not required.
