]]> Guaranteeing full compliance with ASTM D2416, Ayalytical Instruments Electric Conradson apparatus isideal for the determination of the coking value of tar and pitch with an ash content of at or below 0.5%.The instrument works to heat the test sample in a porcelain crucible via electric furnace for apredetermined period of time. The carbon residue remaining following the evaporation and pyrolysis isthen cooled, weighed, and calculated as a mass percentage of the original sample.

Designed with reliability in mind, the Electric Conradson apparatus contains a vertical electric muffle furnace forthe quick heating of test samples, allowing for greater test reproducibility over its gas counterpart. Likethe standard gas Conradson, the electric model is comprised of three concentric crucibles: an Innerheat-resistant glazed porcelain crucible with approximate 30 ml capacity; a center Skidmore ironcrucible, flanged and ringed, and fitted with cover; and an external sheet-iron crucible fitted with cover.The apparatus also comes equipped with an insulating ring block for the maintenance of severetemperatures up to 1100C in accordance with modified Conradson methods, a metal tripod holder withbare Nichrome triangle for the superior stability and support of crucibles during testing, and a sturdy,circular sheet-iron hood with stainless steel, easy-clean chimney for the safe diversion of test vapors.
