1. The temperature of both the cold bath and the cold trap is controlled by a segmented program. The cold bath part adopts a metal bath technology that integrates condenser tubes and refrigeration evaporation tubes, ensuring direct conduction of cold and heat without liquid heat transfer medium, which is both safe and convenient

2. The instrument adopts a lifting and self-locking lifting control technology, and the heating furnace can be quickly raised and lowered, and can be stopped at any position, truly realizing non-polar adjustment technology. At the end of the experiment, the furnace frame automatically slides down, cutting off the residual heat of the heat source and achieving rapid cooling

3. The heating furnace adopts ceramic heating device pulse modulation infrared radiation heating method, with fast heating and cooling speed, ensuring safety and reliability

4. The compressor, heating ceramic element, temperature sensor, and refrigeration diversion valve all use imported components to ensure the accuracy and reliability of instrument data, while also having a long service life and low failure rate

5. Unlimited storage of experimental data and real-time viewing, with built-in micro thermal printer outputting detection results

6. Electric furnace cooling, after the experiment is completed, the cooling fan can automatically start and quickly cool down

7. Infrared modulation optical technology realizes liquid level tracking detection and initial distillation detection, which is not affected by environmental interference, automatically detects the zero position of the volume, and can accurately determine the dry point

8. Coated quartz orifice plate, heat-insulating and non explosive, easy to install orifice plate structure, no need to adjust when replacing orifice plates with different diameters
