AHF Analysentechniks DST-1000 Subboiling Distillation System operates as a practically completely closed system, producing the highest quality acids for demanding analytical applications. The systems high purity fluoropolymer construction allows for the distillation of all of the acids most commonly used in sample preparation and analysis via ICP-OES and ICP-MS, including HF. The instrument is safe and easy to operate. The compact unit is suitable for most laboratory fume hoods, and takes up less than 1 sq/ft of critical working space inside of the hood. The heating mantle surrounding the evaporation chamber gently heats the contents without using lamps or other external heating devices that can corrode in harsh acidic environments.
