GGC-ZY Traditional Chinese Medicine Sulfur Dioxide Analyzer

1、 Product Usage:

The instrument is a new intelligent distillation treatment device that integrates constant temperature heating, automatic control of distillation endpoint, and cooling water circulation according to the laboratory distillation pretreatment operating procedures. This instrument has tested functions such as precise temperature control, automatic anti backflow suction, uniform heating, anti boiling, and intelligent endpoint control. Easy to use, energy-saving and environmentally friendly. After comparison and verification of distillation recovery rates in the metrology certification laboratory, the results are accurate and reliable, with a recovery rate ofMore than 95%.

This instrument can be widely used in various chemical laboratories such as pharmaceutical companies, universities, research institutes, factories, and mining enterprises that require distillation experiments to treat residual sulfur dioxide in traditional Chinese medicinal materials.
2、 Scope of application:

Can be used for pre-treatment of sulfur dioxide residue detection in traditional Chinese medicinal materials and decoction pieces according to the methods specified in the Chinese Pharmacopoeia

comply withDetection of residual sulfur dioxide in traditional Chinese medicinal materials and decoction pieces in the 2015 edition of the Chinese Pharmacopoeia

3、 Technical parameters:
1. The traditional Chinese medicine sulfur dioxide analyzer consists of the following units: four sets of heating control units, one set of built-in cooling water self circulation unit, four sets of nitrogen flow automatic control units, four sets of magnetic stirring control units, timing control unit, and titration unit.

2. Heating method: using far-infrared ceramic heating furnace, infrared radiation heating (no open flame heating, waterproof)

The whole machine has micro boiling and full boiling adjustment, and automatically adjusts the heating power to prevent explosion boiling during the experimental process.

3. Heating units: 4, can be single hole single hole;

4. Heating time: 5-8 minutes

5. Distillation speed: 2-12ml/min (adjustable)

6. Nitrogen device: The host is equipped with a nitrogen main interface with nitrogen protection function, which can control the nitrogen flow rate (60-600ml/min) through a single hole. After the experiment is completed, the nitrogen can be automatically turned off.

7. Control mode: Distillation time can be set simultaneously, heating will automatically stop, high degree of automation, no need for manual supervision.

8. Magnetic stirring control unit:

8.1 * Independent built-in magnetic stirring devices should be installed in the receiving area of each distillation unit, and the stirring speed can be adjusted through an incremental encoder.

8.2 Timing control unit: According to the pharmacopoeia method, each distillation unit should be equipped with an independent timing control device, which can set the working time to 0-200 minutes. After the working time is set, it will automatically count down, and the power can be automatically turned off when the timing ends;

8.3 Titration Unit: The host should be equipped with an independent titration butterfly clip for easy fixation of the burette for titration

9. Single hole power: 0-500W (single furnace, adjustable)

10. Total power: 0-2500W (adjustable)

11. Cooling method: Closed internal circulation reflux system, no need for external cooling water source, built-in cooling water tank, compressor cooling and cooling internal circulation system, suitable for large-scale work, with better condensation effect.

12. Time control: 0-200min (adjustable), can automatically stop working by setting the distillation time. One click water tank adds water, reaches the liquid level, beeps an alarm, and automatically stops adding water.

13. Distillation flask specification: 1000ml X4

14. Receiving bottle specification: conical bottle
