Automatic Distillation Apparatus

I. Product Introduction

Distillation is a very common and important preparation step in the pre-treatment experiments of laboratories at all levels. However, traditional distillation apparatus has independent heating, condensation and receiving units, which is cumbersome to operate, low in efficiency and high in failure rate; the heating temperature is difficult to control, the end point cannot be judged automatically, and the distillate easily siphons back, resulting in poor parallelism and low recovery that directly affect experimental results.

The intelligent integrated distillation instrument adopts an intelligent modular design: methods can be customized, saved and recalled, and are automatically loaded at startup; the condensation unit uses a specially customized serpentine condenser; intelligent end-point control prevents excessive distillation; anti-siphon protection and anti-dry-boiling protection are provided. It achieves simple intelligent operation, automatic distillation, an attractive and practical appearance, energy saving and labor saving while improving sample processing efficiency and reducing labor cost.

III. Product Features

1. Batch processing capacity of 1~6 samples; each channel is independently controlled and each channel is equipped with anti-siphon, excessive-distillation prevention and anti-dry-boiling protection.

2. Controlled by a 7-inch LCD touchscreen; distillation methods can be configured and automatically saved, and can be used directly the next time the instrument is powered on. The system includes a distillation volume (weight) correction function.

3. The heating module uses far-infrared ceramic radiation heating with a bowl-shaped heat source design, ensuring close contact between the sample container (round-bottom flask) and the heat source, with a wide heating power adjustment range, good heating uniformity, high thermal radiation efficiency, fast distillation speed and long service life.

4. The system allows setting of distillation volume and distillation time; operating status, distilled volume and remaining distillation time are displayed in real time. Each distillation unit can be set individually, controlled independently and run independently, stopping automatically when distillation is complete.

5. Distillation end-point control uses dual time and weight modes. When the distillation result reaches the set weight or time value, heating stops automatically, the distillate line is cut off and pressure is released automatically, realizing unattended automatic operation.
