Cyanide Distillation Apparatus
Cyanide, Model B
Cyanide distillation apparatus used in testing for soluble and insoluble cyanides in water. Flask is 1000mL with 24/40 joint and #7 Ace-Thred that permits variable depth positioning of fill tube. Fill tube has been reduced in diameter to retard "boil back" or splattering that occurs with conventional tubes. Still head and cold finger have a 29/42 joint and a #11 Ace-Thred on the medium wall side arm. Two #11 bushings, back to back, hold the threaded adapter to still head by compressing PTFE ferrules against the glass dispersion tube. Because of this feature, the dispersion tube depth is adjustable inside the trap and the fritted end need not be in contact with caustic solutions when not necessary. This will extend the life of the frit and assure consistentdispersion for a longer time. Trap is supplied with #11 Ace-Thred for direct connection. PTFE ferrules are supplied in place of FETFE o-rings for threaded compression fittings. As in Model A, dispersion tube depth is still adjustable. Side arm on trap is 8mm O.D.
