Puridest Water stills
Easy to use and reliable

The highest-quality double distillates

Puridest stills provide ultra-pure, low-gas, germ and pyrogen-free distillate. They purify any raw water to produce a distillate with conductivities down to below 1.6 µS/cm. It complies with DAB regulations and the international pharmacopeia requirements.

These devices are extremely easy to start up and operate. Ultra-pure water can be removed directly after connection to raw water and electricity supplies. The only maintenance required is removing pollutants from the still.

The Puridest devices are an easy and reliable solution anywhere in the world since they do not require any complex service or expensive consumables. LED lamps provide information about operating status and the need for cleaning and make the handling of the Puridest devices even easier.
