Digital controller displays both overhead and flask temperature, along with vacuum reading. Test the range of boiling points for petroleum and bio fuel products with this vacuum distillation system. A distillation curve can be generated relating volume percent distilled and the atmospheric equivalent boiling point temperature. The sample is distilled at a reduced pressure and the initial and final boiling points are measured. Built-in fan reduces cooling time of the distilling flask for shorter turnaround times between tests. Main body of the system is constructed of an aluminum frame and cold-rolled steel walls with a clear protective door for added safety.
