Standard compliant design, for the capable, confident user
Guaranteeing full compliance with ASTM D189, DIN 51 551, IP 13, and ISO 6615:1993, Ayalytical Instruments’ Gas Conradson apparatus is ideal for the manual determination of the coke-forming properties of petroleum oils. The instrument works to heat the oil sample in a porcelain crucible over a gas flame for a predetermined period of time. The carbon residue remaining following the evaporation and pyrolysis is then cooled, weighed, and calculated as a mass percentage of the original sample.
Designed with procedural efficiency in mind, the Gas Conradson is comprised of a Meker lamp with safety valve for the quick heating of liquefied petroleum gas, and three concentric crucibles: an Inner heat-resistant glazed porcelain crucible with approximate 30 ml capacity; a center Skidmore iron crucible, 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 severe temperatures up to 550ºC, a metal tripod holder with bare 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.
