Cyanide distilling apparatus made of PYREX® borosilicate glass to determine soluble and insoluble cyanides in water.

• Very good chemical resistance
• High temperature resistance
• Minimal thermal expansion giving relatively high resistance to temperature changes

Cyanide, as hydrocyanic acid (HCN), is released from cyanide complexes by means of a reflux-distillation and is absorbed in a scrubber containing a sodium hydroxide solution. Tygon® tubing connects the reaction/distillation section to the absorption scrubber, making set-up easier and less susceptible to glass breakage. Inlet tubes have funnel openings for easy addition of acid. Sample capacity: 500 ml.
