    Function introduction


    The upgraded version of 107-1, PLC control, LCD touch screen, anti-dry-burning design, micro-boiling control program for sample heating, common air-cooled internal circulation cooling system.

    Instructions for use
    It can be used for the pretreatment of detection of sulfur dioxide residues in Chinese herbal medicines and decoction pieces in the method specified in "Chinese Pharmacopoeia".
    The 2015 edition of the Chinese Pharmacopoeia stipulates three detection methods for sulfur dioxide: acid-base titration, gas chromatography, and ion chromatography. Gas and ion chromatography have the advantages of high sensitivity and specificity, but the equipment is expensive, which is not conducive to the popularization and use of basic drug testing systems; acid-base titration has the advantages of simple device and low cost, and is a legal detection method stipulated in the Pharmacopoeia. However, since the Pharmacopoeia only describes the glass instrument device of the method, the purchase, assembly and implementation of the whole device still need to be continuously improved. For example: (1) In addition to the glass instrument device, magnetic stirring, electric heating mantle, titration platform, nitrogen device with flow meter, etc. should be equipped and assembled. Many units feel that the purchase of equipment is cumbersome and difficult to assemble and implement, so they cannot carry out this detection method; (2) The assembled devices are varied, and there are unstable nitrogen flow rates, uneven heating, easy gas leakage, and easy bumping during use. , easily affected by the cooling water source, etc., which lead to the phenomenon of poor parallelism and low recovery rate that directly affect the test results; (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 testing of secondary medicinal materials is time-consuming and labor-intensive.

    Instrument innovation
    (1) Heating, distillation reflux, cooling, nitrogen blowing control, magnetic stirring, receiving six integrated design;
    (2) The closed cooling water automatic cooling and circulating return device does not need external tap water cooling, saving energy and reducing consumption;
    (3) The far-infrared ceramic heating device is used to replace the ordinary electric heating furnace or electric heating mantle, which is more energy-saving, has good waterproof effect and is resistant to acid and alkali corrosion;
    (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) Additional nitrogen protection function, the nitrogen blowing flow rate can be adjusted independently per hole (60-600ml/min);
    (6) The original design of the "Chinese Pharmacopoeia" reflux condenser
    (7) There is a built-in magnetic stirrer at the bottom of the receiving bottle, and the stirring speed can be monotonous in a single group;

    Applicable units and testing items:
    All levels of Chinese medicine inspection and testing, Chinese medicine R&D and production enterprises, Chinese medicine and other units that need to detect sulfur dioxide residues in Chinese medicines, medicinal materials, and decoction pieces
