Regular Sulphite/Cyanide Distillation Apparatus TLG®

This cyanide distilling apparatus is used in testing for soluble and insoluble cyanides in water. Cyanide as hydrocyanic acid (HCN) is released from cyanide complexes by reflux distillation and absorbed in a scrubber containing sodium hydroxide solution. The cyanide ion in the absorbing solution is then determined colorimetrically or by volumetric titration. Apparatus meets EPA and ASTM requirements.
