Milestone has developed the Duopur, a sub-boiling distillation system that allows laboratories to make their own high-purity acids.
The Duopur can produce one litre (500ml per quartz unit) of high-purity acid from reagent grade acid in about six hours.
The Duopur consists of two high-purity quartz distillation units.
Each unit contains two infrared heating elements, a water-cooled condenser and a reagent collection bottle.
The distillation process is microprocessor controlled, allowing the user to set the distillation time and power level.
Using a Duopur system, ultra-trace water and acids can be prepared from standard reagent grade, saving up to 90 per cent of the cost of purchasing ultra-pure reagents.
The unit is programmable for efficiently distilling different acids and mixtures.
All parts in contact with purified reagents are constructed of high-quality quartz and PTFE materials.
The Duopur also provides the ability to re-purify acids that have become contaminated.
