How is the boiling range determined?

Thread Content

The SY7534B fully automatic boiling range analyzer is designed and manufactured in accordance with the latest national standard GB/T7534-2004 for the determination of the boiling range of volatile organic liquids used in industry, as well as the standard methods for determining the distillation range of methanol and alcoholic products. It is suitable for organic liquids with boiling points between (30–300)°C under normal pressure, and those that maintain stable chemical properties during the distillation process (such as hydrocarbons, esters, alcohols, ketones, ethers, and similar organic compounds). Performance features: 1. The heating and cooling during the boiling range determination process, level monitoring, temperature recording, printing, and other functions are all carried out automatically. 2. It features a built-in micro thermal printer that automatically reports the test results, enabling boiling range determination with just one button press. 3. The testing process complies with standard requirements, ensuring reliable data. The detection method is reliable and offers good reproducibility. 4. The imported infrared level detection system is not affected by indoor lighting, ensures accurate readings of the recovery volume, and offers a detection precision that exceeds **the standard. Technical specifications: 1. Display type: Embedded industrial-grade color touch screen. 2. Cooling method: Refrigeration using compressors imported from Germany. 3. Temperature range: Room temperature to +500°C, with an accuracy of ±0.1°C. 4. Heating method: Electric heating element, with a maximum heating power of 800 W. 5. Temperature sensor: Pt 100 glass probe imported from Germany. 6. Volume detection range: 0 to 100 mL, with a resolution of 0.01 mL. 7. Constant temperature range for the cold bath: -10 to +70°C. 8. Distillation rate: 4 to 5 mL/min. 9. Power supply: AC220V 50Hz. 10. Maximum power: 1500 W. 11. Operating temperature range: 10 to 40°C℃
