Make your own ultrapure acids Reviews by SelectScience 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 HNO 3 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 Request a quote Questions Questions?

“In the preparation of high purity reagents, there is only one significant and practical choice for the method of purification: sub-boiling distillation" US EPA SW-846, Chapter 3, Update IVB. Why sub-boiling technology? The chemical reagents used during the analysis are an important source of the analytical blank. Sub-boiling distillation has been demonstrated to be the best method of acid purification. It uses contactless infrared lamps to vaporize the surface liquid at a temperature typically 20°C below the boiling point. In contrast to conventional distillation, where strong boiling action generating aerosolized particles results in contamination of the original liquid with the distillate, a gentle surface evaporation during sub-boiling distillation prevents the formation of spray or droplets and yields to a very high pure acid. Compare sub-boiling and traditional distillation duoPUR Quartz sub-boiling system The duoPUR consists of two quartz distillation units. Each unit contains two infrared heating elements (1), a water cooled condenser (2), a high-purity PFA collection bottle (3), and a fully automatic acid loading/discharge system. The vaporized liquid is collected on the i
