Applicable standards: GB/T9168、ASTM D1160。
■ Functional features:
10.4-inch touch screen workstation operation, human-machine dialogue, automatic control, simple operation, convenient control.
◇ Fully automatic control: Press one button to start and complete experiments, automatically distill, and automatically adjust distillation speed.
Real time display of distillation curves, statistical recording, data conversion to WORD, EXCEL storage and printing on the WINDOWS operating system
The experimental results can be uploaded through LIMS.
The vacuum pressure sensor adopts the American MKS pressure sensor. Pressure detection is more stable and reliable!
◇ Automatic determination of initial boiling point, recovery volume corresponding to any distillation temperature, distillation temperature corresponding to any recovery volume, and automatic pressure
Conversion.
Real time display of distillation temperature curve and sample heating temperature curve.
Three ways to end the experiment: end of final boiling point, end of temperature and volume. After the experiment, the electric furnace is equipped with automatic fan cooling
But the function.
◇ It has the functions of setting the distillation temperature, automatically detecting the distillation volume, and automatically reducing the distillation temperature under atmospheric pressure
Conversion function.
Built in self checking calibration system: capable of correcting vacuum degree, sensor temperature, and cylinder volume.
The temperature chip, photoelectric tracking, platinum resistance sensor and other detection circuits, as well as the refrigeration system, are imported components with precise vacuum control
The system has a constant low pressure of 0.1MMHG.
◇ Automatically control vacuum pressure, cold trap temperature, and graduated cylinder temperature.
Imported vacuum pressure detection, three-level negative pressure control, high-precision constant negative pressure, automatic control of vacuum degree and negative pressure according to different oil products
Pressure range: 0.133KPA, 0.267KPA, 0.667KPA, 1.33KPA, 2.667KPA, 6.6667KPA.
◇ Negative pressure control accuracy: ＜ 1KPA: 0.01KPA,> 1KPA: 1/100, ultimate vacuum ≤ 1.33PA.
The temperature of the cold trap is kept below -40 ℃, effectively adsorbing oil vapor and preventing sudden boiling phenomenon. The temperature can be freely selected.
The flask branch and receiving cylinder have heating and temperature control functions, automatic control of the cylinder chamber temperature and distillation rate, and automatic detection of samples
The distillation temperature and volume, the temperature of the measuring cylinder chamber, the vacuum degree of the system, the distillation temperature and volume can be displayed in real time.
