DuoPUR and SubPUR

Make your own ultrapure acids

Reagents contaminations increase the background concentration of the analytes present in a sample.

Therefore, many laboratories purchase expensive high purity acids for trace elemental.
There is, however, an alternative: Milestone has developed the DuoPUR and SubPUR, a sub-boiling distillation system which allows laboratories to make their own high purity acids at dramatically reduced costs.

Main Advantages

• Up to 90% cost saving of ultra-pure acids by purifying low cost reagent grade acids
• High productivity, up to 3 liters in 8 hours
• Continuous supply of fresh high purity acids
• "On-demand" acid purification
• Re-purification of contaminated acids
• Single or double distillation upon on requirements

The author, Dr. Robert Richter, explains the most useful techniques for the Modern Laboratory.
