A programmable, fully automated, self contained distillation unit designed and manufactured by Orbis BV, featuring the unique liquid/refrigerant free "Solid State" condenser and cooled receiver compartment.
Distillation programs, comprising temperature/time profiles and volume setpoints, can be downloaded from a personal computer or entered via the control panel. Up to 10 programs can be stored in the on-board memory, and can be modified whilst using the 'Learn' facility. The unit continually measures the temperature of vapour in the distillation flask, the volume of distillate in the receiver, and the time interval. Whenever a setpoint is reached these parameters are recorded. The readings are corrected automatically from data supplied by the integral precision electronic barometer. The results memory can hold up to 28 datasets of 100 volume setpoints.
To ensure conformity to ASTM D86, the temperature in the flask is measured by a digital system that incorporates dynamic simulation models of ASTM 7C/F and 8C/F mercury-in-glass thermometers. The probe carries an embedded calibration curve. Re-calibration can be carried out by the user via the distillation unit.
