duoPUR

Quartz sub-boiling distillation system

Sub-boiling distillation has been demonstrated to be the best method and the most effective approach in acid purification. Offering an optimal purification method for preparation of high purity reagents, this type of acid distillation uses contactless infrared lamps to vaporize the surface liquid at a temperature typically 20°C below the boiling point. The duoPUR allows the purification of the most common acids such as HNO3 and HCl.

In contrast to conventional distillation systems, where strong boiling action generating aerosolized particles results in contamination of the original liquid with the distillate, the duoPUR acid purification system using sub-boiling technology provides gentle surface evaporation preventing the formation of spray or droplets and yields to ultrapure acids. The duoPUR offers an alternative to the purchase of expensive high purity acids for trace elemental analyses.

• Up to 90% cost saving of ultrapure acids
• High productivity
• ‘On-demand’ acid distillation
• Single or double distillation upon on requirements
