The i-Fischer® AUTODEST 850AC is a fully computer controlled vacuum distillation unit of turn-key design, and ready for use after installation and commissioning. The unit extends the current test method and does not limit your vacuum distillation testing options.

You are able to define your own tailored program also beyond the current standard. The system is fully housed and equipped with doors in the front and rear to satisfy safety requirements and to facilitate service aspects.

The protocol is printed out simultaneously to the distillation and the distillation curves in actual boiling temperatures (ACT) and atmospheric equivalent temperatures (AET) as well as essential distillation parameters are shown on the monitor.

The final data and the distillation curves are printed and stored on harddisk and/or data disks.

Features

• Fully automatic vacuum distillation apparatus according to ASTM Dl 160 with PC, printer and data transmission facilities
• Unit is fufly housed regarding to additional safety aspects, all front parts arc made transparent for convenient viewing of the whole distillation process
• Easy maintenance of the system in spite of fuily honsing, all components can be reached easiiy for dismantiing and reassembiing
• PC  will be supplied directly from manufacturer with printer, software allowing to run and control the distillation through monitor and keyboard / mouse.
• Temperatures can be switched between °F and °C
• Caiculation of the distillation data, monitoring and printing of the distillation curves,boiling temperatures (ACT and AET), charge temperatures and distillation rate versas the yield (vol%)
• Programmable set for condenser temperature following the vapour temperature
• Recalling of distillation protocols and curves at any time
• All controlling distillation pararneters can be modified at any moment
• Speciai software feature with “Supervisory Mode“ for operating (partiy or totaily) the unit manually by overruling the automatic control with indication of every manuaily operated controi Ioop in the bw chart
• Calibrating procedure for all temperature and vacuum sensors
• Automatic calibration of volume measuring system delivers accurate detailed distillation data, precise volume measurement
• Volume follower system for automatic control of the distillation rate and heating rate, equipped with light barrier and stepper motor (resolution and accuracy better than 0.05 ml)
