Quartz sub-boiling
distillation system

In the preparation of high purity reagents, there is only one significant and choice for the method of purification:
sub-boiling distillation.

US EPA SW-846, Chapter 3, Update IVB.

Sub-boiling technology

watch 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.
