Distilled Water is produced by vaporizing Drinking Water or a higher quality of water and condensing it into a purer state.
It is used primarily as a solvent for reagent preparation, and it is also specified in the execution of other aspects of tests, such as for rinsing an analyte, transferring a test material as a slurry, as a calibration standard or analytical blank, and for test apparatus cleaning.
Distilled Water is also cited as the starting water to be used for making High-Purity Water (see High-Purity Water).
Because none of the cited uses of this water imply a need for a particular purity attribute that can only be derived by distillation, water meeting the requirements for Purified Water derived by other means of purification or Water for Injection could be equally suitable where Distilled Water is specified.
It is the user’s responsibility to verify the suitability of Purified Water or Water for Injection
