ST107-1RW Traditional Chinese Medicine Sulfur Dioxide Analyzer
Introduction: It can be used for the pre-treatment of the detection of sulfur dioxide residues in Chinese herbal medicines and decoction pieces in the methods prescribed in the Chinese Pharmacopoeia. The 2015 edition of the Chinese Pharmacopoeia stipulates three detection methods for sulfur dioxide: acid-base titration, gas chromatography, ion chromatography, etc. Gas phase and ion chromatography have the advantages of high sensitivity and specificity, but the equipment is expensive, which is not conducive to the popularization of primary drug testing systems; acid-base titration has the advantages of simple equipment and low cost, and is a legal testing method prescribed by the Pharmacopoeia. However, since the pharmacopoeia only describes the glass instrument device of this method, the purchase, assembly and implementation of the entire device need to be continuously improved. For example: (1) In addition to the glass instrument device, it needs to be equipped with magnetic stirring, electric heating mantle, titration platform, nitrogen device with flow meter, etc., and assembled. Many units feel that the purchase of equipment is too cumbersome and the assembly and implementation are difficult to carry out this detection method; (2) The assembled devices are diverse, and there are unstable nitrogen flow rates, uneven heating, easy leakage, and easy bumping during use. , It is susceptible to problems such as the influence of the cooling water source, and the corresponding phenomenon that directly affects the test results such as poor parallelism and low recovery rate; (3) The work efficiency is low. The current equipment adopts a single device, which is difficult to process multiple samples at the same time. The simultaneous inspection of secondary medicinal materials is time-consuming and laborious. Features: (1) Six-position integrated design of heating, distillation reflux, cooling, nitrogen blowing control, magnetic stirring, and receiving; (2) Closed cooling water automatic cooling and circulating return device, without external tap water cooling, energy saving and consumption reduction; (3) Use far-infrared ceramic heating device to replace ordinary electric heating furnace or electric heating mantle, which is more energy-saving and has good waterproof effect and acid and alkali corrosion resistance; (4) 4 sets of samples can be made at one time, and the heating power can be adjusted by a single hole (knob type); (5) With the addition of nitrogen protection function, the nitrogen blowing flow rate can be independently adjusted for a single hole (60-600ml/min); (6) "Chinese Pharmacopoeia" original design reflux condenser (7) A magnetic stirrer is built into the bottom of the receiving bottle, and the stirring speed can be single group and monotonous; technical parameter: Model: ST107-1RW (designed for the residual sulfur dioxide of Chinese herbal medicines and decoction pieces) Display mode: LCD touch screen Heating method: far infrared ceramic heating (no open flame heating, low power consumption and high efficiency) Nitrogen blowing control: The host is equipped with a nitrogen general interface, and the nitrogen flow of a single hole can be individually controlled by a flowmeter Magnetic stirring device: Four sets of magnetic stirrers are built into the bottom of the receiving bottle, and the stirring speed can be single set and monotonous Cooling method: Built-in compressor forced refrigeration cycle system, without external tap water cooling Temperature control: Built-in micro-boiling heating control system, temperature control range 0-200℃ Number of distillation units: 4 groups Distillation flask specifications: Standard configuration: 1000ml flask Receiving bottle specifications: Standard configuration: 100ml×4 conical flask Rated power: 3000W Rated voltage: 220V/50HZ Dimensions (mm): 960*575*413 Leakage protection device: Yes Anti-dry design: Yes Scope of application: It is suitable for the pre-distillation treatment of the residual sulfur dioxide of Chinese herbal medicines and Chinese herbal medicines
