This cyanide distillation apparatus is used in testing for soluble and insoluble cyanides in water

Two #11 bushings, back to back, hold the threaded glass adapter to the still head by compressing PTFE ferrules against the adjustable depth glass dispersion tube. The frit on the dispersion tube is 10-20 micron. The trap has a top [ST] 19/22 joint. The threaded glass adapter has a 5/16" hose connection. Fabricated from borosilicate glass.

Flask is 1000mL with [ST] 24/40 joint and #7 Ace-Thred that permits variable depth positioning of the fill tube. The fill tube has been designed with a float valve for added protection against “boil back,” or splattering, that occurs with conventional tubes. The still head is jacketed and lengthened for more efficient condensing. Both the head and the cold finger have [ST] 29/42 joints, and there is a #11 Ace-Thred joint on the side arm of the head.
