Plat Chg. 17For the “Sample Class” select “General” and for “Operator” select “Labtech”. 18Click the Start button to begin the distillation. 19 Once the distillation is complete, the instrument will signal with an audible alarm; press the ACK key on the unit to turn off the signal or allow it to continue until it shuts off after about a minute. 20Remove and clean all glassware including thermometer – place thermometer in glass receptacle at oven corner to store. 21Check distillation data to ensure all parameters are within limits specified by ASTM D86, ex. Distillation rate between 4-5 ml/min. 22 If all parameters are acceptable, click on the “Acknowledge” button on display screen on PC and a box will pop up where the amount of residue is entered to 1 decimal place. 23Click “Okay” to initiate data transfer to Labworks.
