SKD-3104 Intelligent Sulfur Dioxide Distillation Instrument, 4 Channels, SHANGHAI PEIOU ANALYSIS INSTRUMENT CO.,LTD (CAT#: STEM-AIAE-3381-LGZ)

Distillation unit: 4 channels
Actual operation: 7-inch high-definition touch LCD screen
Control core: PLC control
Heating method: far-infrared ceramic radiation heating, no open flame
Heating time: ＜8min
Temperature control: (room temperature～450)°C
Time control: 1-600min
Anti-suck back function: built-in anti-suck back protection
Distillation endpoint control: Weighing endpoint control + timing control
Distillation end point accuracy: ±2g (actually up to ±0.1g)
Distillation volume setting: 1-600g
Single hole single control: yes
Cooling method: External refrigeration compressor
Built-in method: The built-in distillation method can be directly selected or edited to save the method. You can customize the method and save the application according to the experimental needs without frequently entering repeated data.
Automatic design: one-key cleaning, one-key setting for 4 channels of the same distillation parameters.

Unattended: The system automatically completes heating, peeling, temperature control, compressor refrigeration, cooling water circulation and distillation end point judgment.
Heating module: Using advanced far-infrared ceramic radiation heating technology, no open flame, low power consumption, high efficiency, long life, uniform heating, not easy to bump, and corrosion resistance. Each heating component can be controlled independently without interfering with each other.
Refrigeration cycle module: External refrigeration: External customized small-volume compression refrigeration components, cooling water closed circulation, saving space.
One-key cleaning function: The distillation apparatus is equipped with an automatic cleaning pump, and there is no need to disassemble the bottle body. After the experiment, the distillation pipeline can be cleaned directly with one key, which is convenient, fast, safe and efficient.
Distillate anti-suckback: When the effluent reaches the set end point, the outlet of the effluent is automatically locked, and the built-in suction valve is automatically opened, so that accurate weighing and anti-suckback are both correct.
Distillation dual mode: Weighing distillation: (1-600) grams can be freely set, using high-precision weighing end-point detection module, the distillation will automatically stop when the distillation end point is reached.
Timing distillation: (1-600) minutes can be set arbitrarily, according to the set time distillation, the distillation will be automatically stopped when the time is reached.
The two modes can be selected arbitrarily, and the distillation mode of each unit can be set independently.
Built-in method: There are seven built-in distillation methods in the distillation apparatus, and the method can be directly selected without frequent input of repeated data; the method can also be customized and saved according to the experimental needs.
Automatic precision distillation: After the distillation volume reaches the set value, the liquid outlet will be automatically locked to prevent excessive distillation caused by waste heat and ensure that the precise distillation is not excessive.
Automatic lifting device: When the distillate is 200mL, the lower end of the condenser tube will automatically leave the liquid level, and then distill for 1min, which meets the requirements of the national standard.
Automatic nitrogen control: automatically control the opening of nitrogen without manual operation.
