Acid stills
Acid stills
SPEX CertiPrep's sub-boiling acid stills employ infrared heaters to distill impurities through surface evaporation without boiling. A single distillation can reduce most impurities below parts per billion. Acids are available in dimensions of 27W x 27D x 60H. The PTFE still handles all acids except sulfuric acid, and the Quartz still handles all acids except hydrofluoric acid. Both stills produce 50 mL/h of operation.
