Introduction:
Sample distillation is a commonly used and important pretreatment application for sample pretreatment. It is widely used in laboratory sample testing at all levels, but it is limited to cumbersome experimental operations, low distillation efficiency, and complex distillation unit distillation. The process is extremely prone to danger, leading to distillation failure and affecting work efficiency. This product adopts intelligent automatic design, integrates far infrared radiation heating module, cooling water circulation device and optical fiber terminal controller. The whole process does not need manual control, microcomputer control, simple operation, energy saving, accurate temperature control, automatic distillation and circulation. Condensation, anti-back suction, explosion-proof boiling, intelligent end point control, cooling water backflushing and air tightness detection. Applicable to food, water, soil, solid waste and other sample testing projects: cyanide, volatile phenol, COD, ammonia nitrogen and other pre-treatment projects using distillation. State of the art: Distillation is a common and important pretreatment method for sample separation and purification of liquid mixtures. Although conventional distillation units can achieve basic distillation functions, the following problems exist:
1. The connection of the distillation device is cumbersome, the space occupied is large, the safety of the experiment is not guaranteed, and the labor intensity is large;
2. The traditional distillation device is directly heated by open flame or high-power electric furnace, which has large power consumption and uneven heating, and is easy to bump;
3. The temperature of the heating source is uncontrollable during the distillation process, which easily causes the bottle to burst, resulting in short circuit, leakage, and poor safety;
4. The cooling water source uses tap water, which cannot be recycled and wastes water resources;
5. The distillation end point needs to be manually controlled, and there is no anti-back suction protection, which often leads to distillation failure. Technical advantages: on the basis of the traditional distillation device, the mold power adjustable heating system, the circulating condensation system, the terminal control system, and the anti-back suction system are combined, with double control of knob and button, automatic temperature control, constant temperature heating, cooling water sealing Cycling, distillation end point automatic control, end point alarm, anti-back suction, cooling water backflushing and flow path air tightness detection, etc., no need for personnel to be on duty, safe and reliable, practical and convenient, environmental protection and energy saving.

2. Non-open flame mold ceramic or high-purity aluminum heat source bowl, special surface coating treatment.
3. Far infrared radiation heating, high heat conversion efficiency, precise temperature control, uniform heating, no bumping and waterproof and corrosion resistance.
4. The distillation unit can be arbitrarily combined to complete the distillation of 2-12 samples at one time. The efficiency is high and the single hole can be controlled. The heating power, heating time and distillation amount can be set freely.
5. Customized special snake-shaped condensate bottle with independent intellectual property rights, the airflow is smooth, no reflow, and the condensation efficiency is more than twice that of the conventional condensing bottle.
6. Closed cooling circulation water source, compressor refrigeration, even in the hot summer, there is no need to connect external tap water source, the water temperature is constant within 20 degrees, to meet the condensation work under different working conditions.
7. The distillation end point control adopts the imported digital optical fiber level sensor and the weight sensor dual end point control mode.
8. The distillation amount and the receiving bottle specifications can be arbitrarily set and selected. After the set value is reached, the power failure will be automatically stopped and the sound and light alarm will be prompted.
9. With anti-back suction protection, avoid distilling the distillate and pour it into the flask to ensure no loss of labor results.
10. China's first atmospheric pressure, temperature and humidity combined with environmental protection and energy saving mode, the instrument can automatically adjust the heating power, constant distillation speed, and good repeatability.
11. The distillation speed is 1-12mL/min continuously adjustable, which can be arbitrarily set according to the requirements of different methods such as cyanide, volatile phenol and ammonia nitrogen. For example, the cyanide HJ standard is 2-4ml/min, which meets the standard. Classic methods require speed, repeatability, and precision.
12. The automatic scan code system can be upgraded, and the experimental information data is automatically imported into the laboratory LIMS system without manual recording.
13. With cooling water back-blowing function, after the distillation is finished, the cooling water is automatically blown back to the cooling water tank to avoid the loss of cooling water during the condensing bottle disassembly process.
