Conradson Manufacturer,Supplier and Exporter in India
Product Code : EL-MLE-13265
Jlab Export is a leading Conradson Manufacturer,and suppliers in India
Conradson (code EL-MLE-13265) is a carbon residue apparatus of the Conradson type that determines how much carbon an oil leaves behind after evaporation and pyrolysis. It is built for the ASTM D189 and IP 13 methods and comes with three nested crucibles, an insulating ring block, a tripod with nichrome triangle and a stainless steel chimney. Each Conradson set, crucibles and chimney included, is made by JLab in Ambala, India.

How the Carbon Residue Is Measured
A weighed oil sample goes into the inner porcelain crucible, which sits inside the middle iron crucible with its Skidmore lid; both go into the external iron crucible, which rests on the nichrome triangle within the insulating ring block. Strong heating drives off the volatile part of the oil, and its vapours burn above the chimney, while the heavier fractions crack in a destructive distillation and leave a carbon-rich residue. After cooling, the residue is weighed and reported as a percentage of the sample mass, a figure that indicates how readily the oil forms carbon deposits when heated.
