Product Description
Interfering substances can skew cyanide results, and a dedicated distillation setup removes them before analysis. This complete kit lets water and wastewater labs perform the acid reflux distillation described in ASTM D2036, isolating cyanide as HCN and capturing it in an alkaline absorber for accurate downstream measurement.
This listing is for Wheaton catalog number 377160: CLEAR-SEAL Cyanide Distillation Kit, Complete Unit. In use, the sample reacts with sulfuric acid and magnesium chloride, converting cyanide to hydrogen cyanide, which distills over and is trapped in sodium hydroxide solution for CN analysis. Glass parts are WHEATON 33 low extractable borosilicate meeting ASTM E438 Type I, Class A, and the components join with standard taper CLEAR-SEAL joints for a tight, grease-free assembly. LIGHT LABS ships genuine DWK Life Sciences products with knowledgeable support from our Englewood, Colorado team.
