Make distilled water yourself - that's how it works

It does not have to be to buy distilled water. With a little time and skill, distilled water can also be made by yourself. How it works, what you need, and how best to make and store distilled water is explained here.

Basics of distillation

Distillation always works on the principle that water first evaporates and then condenses on a colder surface. During evaporation, all impurities and all substances dissolved in the water remain behind - the condensate is completely pure H2O.

For distilling water is not necessarily a distillation flask required. You can also manage well with funds from your own kitchen. The principle always remains the same.

Distilling with pot and lid

Fill a pot (preferably made of stainless steel) with tap water for approximately two-thirds. Then bring the water to a boil.

A bowl is placed on the water surface. If she does not swim by herself, it's best to put her on a suitable stand. This is about the grill attachment of the microwave.

When the water boils, put a lid on the pot. The lid handle must point inwards, into the pot. The pure steam now fogs on the lid and drips into the bowl. What is caught in the shell is distilled water.

To speed up the process, you can put ice cubes on top of the lid. They cool the lid and thus accelerate the condensation process. The shell becomes full faster.

Bottling the distilled water

The filling of the recovered distillate goes out of the shell easily. The container should be clean. If germ-free distilled water is required, the container and its closure, as well as the funnel, must also be germ-free. This is best achieved by boiling the container, cap and funnel for at least 10 minutes.

Storage of distilled water

As a rule, distilled water can be stored indefinitely, as long as it is protected from dirt and air. In glass bottles, however, the shelf life is limited because distilled water reacts aggressively and dissolves silicates over time from the glass. As a result, it is increasingly contaminated after some time.

The best is the storage in a plastic container.

Sterile distilled water

If the distilled water is sterile, the lid and the glass bowl should be boiled before distilling. Care must be taken to ensure that no contamination occurs when transferring to the boiled container. If possible do not touch the water with your hands.

If in doubt, you can also sterilize the distilled water with a Steripen again. As long as it is kept under exclusion of air, it also remains germ-free.

Tips & Tricks

Germ-free, distilled water is almost never needed in the home. So you do not have to worry about that.
