Deionised Water - 1L

Deionised Water is a highly purified form of water that has had its mineral ions (e.g. calcium, magnesium, sodium, and chloride) removed through a process called ion exchange. 

This non-conductive water is almost completely free of dissolved solids, making it the ideal choice for cleaning delicate equipment without leaving a residue. 

The purity of this laboratory-grade water also ensures accuracy during tests, eliminating the variables caused by dissolved ions.

Free of mineral ions such as calcium, magnesium, and sodium, Deionised Water (DI Water) can be used to clean delicate equipment without scratching the instrument or leaving behind a residue. 

It can also be used for laboratory testing, ensuring accuracy by removing the variables caused by dissolved ions.

Additionally, Deionised Water can help to prevent mineral build up, extending the lifespan of machinery and devices. It is also widely regarded as the more sustainable alternative to Distilled Water, minimising waste and driving standards of efficiency. 

Although it is used throughout the food industry, Deionised Water is also a popular choice across the electronics industry, due to the fact that it doesn't conduct electricity. 

Key Features

  • Free of mineral ions: ensures purity and eliminates residue
  • Suited to sensitive applications
  • More sustainable than distilled water: minimises waste and drives efficiency
  • Won't conduct electricity 


Distilled Water is purified by boiling and condensing the steam, while Deionised Water is purified by removing ions using resin beads. Both waters are pure, but Deionised Water is often preferred for scientific and industrial uses due to its higher purity level and efficiency.
Deionised Water is commonly used at food and drink production sites, often in their on-site laboratories. It is also used across the electronics, medical, and pharmaceutical industries.
Deionised Water should be stored in clean, airtight, and non-reactive containers (e.g. glass or high-grade plastic) to prevent contamination.
