Description

Think Pure. 

The Milestone subCLEAN is a compact and easy-to-use sub-boiling system, where all parts in contact with acids are made of high-purity fluoropolymers. The subCLEAN is therefore suitable for the purification of HF, as well as for HNO3 and HCl.

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.

How it Works

The acid is automatically loaded into the distillation container, where it is gently heated below its boiling temperature.
All process is microprocessor controlled by using a compact control terminal with easyto- read, bright, full-color, touch-screen display.

The subCLEAN does not require cooling water or a chiller, as acid vapors rapidly condense into a collection bottle by forced air cooling.

SCHEMATICS

Make Your Own Ultrapure Acids

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.
