 The OmniPure Sub-Boiling Distillation System is a fully automated unit with all wetted parts composed of inert, high-purity Teflon® PFA and FEP. The distillation assembly consists of a directly heated distillation container and an
air-cooled condensation bottle. No external cooling system is required.
The OmniPure uses a closed design with a standard storage bottle for collection,
eliminating potential contamination from open-air or transfer bottles. The system is
designed for easy disassembly, cleaning, and exchange of still assemblies. A sliding
bottle rack with a built-in tray provides further ease of use, while protecting against
accidental liquid spillage.

Elements were spiked at
10μg/L in the original reagent grade
HNO3. Concentrations for many elements
are below the detection
limit.
Note: Distillation was performed under non-cleanroom conditions.
