Cleaning various items used in ultra-trace analysis work is a critically important laboratory routine. To minimize contamination, traditional cleaning methods require soaking items in hot acids, often for several hours. To be effective large volumes of acid are consumed and need to be changes regularly. There is also a substantial risk of exposure to hot acids and acid vapors using traditional soaking techniques.
To address these issues, Milestone has developed the traceCLEAN, a fully automated, self-contained, acid steam cleaning system for trace metal analysis accessories. The cleaning process with the traceCLEAN takes about an hour, enhancing the overall lab workflow. Digestion vessels, ICP accessories, volumetric flasks, and other glassware can be cleaned, even multiple times during a day.

  For all laboratory apparatus, either TFM, glass and quartz parts
• Fully automated and safe
  No operator exposure to acid vapors.
• Highly productive
  Fast, convenient, clean, and fully automated.
• Cost-effective and productive
  No changing of acids or soaking required.

The chemical reagents used during the analysis are an important source of the analytical blank. Sub-boiling distillation systems has been demonstrated to be the the leading method of acid purification.
In contrast to acid purification through conventional distillation, where strong boiling action generating aerosolized particles results in contamination of the original liquid with the distillate, acid distillation system using sub-boiling technology prevents the formation of spray or droplets and yields to a very high pure acid.
subCLEAN is a compact and easy-to-use sub-boiling system, where all parts in contact with acids are made of high-purity fluoropolymers. Offering an optimal purification method for preparation of high purity reagents, our subCLEAN system is therefore suitable for HF, as well as for HNO₃ and hydrochloric acid purification.

• Up to 90% cost saving of ultrapure acids
• High productivity
• ‘On-demand’ acid purification
• Re-purification of contaminated acids

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
