**Hot water for injection (WFI)** is essential in the **pharmaceutical** and **biotechnology** sectors for several important uses, including:

1. The **preparation of pharmaceutical solutions** such as sterile drugs and vaccines, where hot water for injections is used as an excipient to be sure that the water used is free of contaminants and safe for human use.

1. **Washing and cleaning of equipment** **and containers** used in the production of medicines, ensuring that they are free of impurities and bacteria that could contaminate the final product.

1. The preparation of single doses useful for the **dilution of concentrated and lyophilized pharmaceutical substances** in order to obtain the desired concentration for medical use, assuring that the water used is safe and free of contaminants that could alter the composition of the final solution.
