The Milestone duoPUR is a unique system for sub-boiling the distillation of acids, water, and reagents for ultra-trace applications.

By using a duoPUR system, ultra-trace water and acids can be prepared from standard reagent grade, saving up to 90% of the cost of purchasing ultra-pure reagents.

The duoPUR is microprocessor controlled and programmable for efficiently distilling different acids and mixtures. All parts in contact with purified reagents are constructed of high quality quartz and PTFE materials.
