Puridest water stills for distillation is among the most reliable and robust laboratory water treatment systems in the world. Provide ultra-pure, low-gas, sterile and pyrogen-free distillate for the dilution of reagents, sets of samples and more. Puridests 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. Optionally with 1 or 2 distillation stages, they achieve excellent conductance values. Glass stills provide water that is virtually free of metal ions.rMaintenance can be done without specialized personnel. It is limited to cleaning separated contaminants from the evaporator chamber. Glass stills do this automatically.rThey only require electricity and water, without the need for cartridges, adsorbents or to regenerate ion exchangers.rAfter connecting the water and power supply, pure water is produced at the touch of a button.
