Tap water contains a mix of ingredients which should never to put into an autoclave.
A water distiller produces 99% pure water which will extend the life and optimise the performance of your autoclave.
The distiller works by gently boiling the water to remove impurities and leave pollutants behind. The steam gathers in a stainless steel coil where it then cools, forming pure water. This water is then filtered through a charcoal filter to remove any final traces of impurity.
