    It can batch process 8 samples at one time, automatic timing reflux, automatic acid addition, automatic nitrogen blowing, super cost-effective! It is suitable for all levels of food, traditional Chinese medicine inspection and testing, customs, food and traditional Chinese medicine processing enterprises, scientific research institutes of universities, etc.


    Instructions for use

    GB5009.34-2022 "Determination of Sulfur Dioxide in Food"; 2015 and 2020 editions of "Chinese Pharmacopoeia" to detect residual sulfur dioxide in Chinese herbal medicines and decoction pieces

    GB5009.34 and the 2015 edition of "Chinese Pharmacopoeia" stipulate three detection methods for sulfur dioxide: acid-base titration, spectrophotometry (food) / gas chromatography (traditional Chinese medicine), ion chromatography, etc. Spectroscopy/gas phase and ion chromatography have the advantages of high sensitivity and strong specificity, but the equipment is expensive, which is not conducive to the promotion and use of grassroots food and drug inspection systems;

    The acid-base titration method has the advantages of simple equipment and low cost, and is a statutory detection method stipulated in the national food standard and pharmacopoeia. But because they are all glass instrument devices that only describe the method, the purchase, assembly and implementation of the whole set of devices still need to be continuously improved. For example: (1) In addition to glass equipment, 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 too much and cumbersome, and the assembly and implementation are difficult, so it is impossible to carry out this detection method; (2) The assembled devices are varied, and the nitrogen flow rate is unstable, uneven heating, easy to leak, and easy to bump during use. , Susceptible to the influence of cooling water sources, etc., which directly affect the test results such as poor parallelism and low recovery rate; Simultaneous inspection of medicinal materials is time-consuming and labor-intensive.

    Instrument Innovation
    (1) Seven integrated design of heating, distillation reflux, automatic acid addition, cooling, nitrogen blowing control, magnetic stirring, and receiving;
    (2) The far-infrared ceramic heating device is used instead of ordinary electric furnace or electric heating jacket, which is more energy-saving, has good waterproof effect and is resistant to acid and alkali corrosion;

    (3) Through the front LCD touch screen, functions such as nitrogen blowing before acid addition, automatic acid addition, and automatic nitrogen start-up control for samples can be realized;

    (4) 8 samples can be made at a time, and the heating power can be adjusted for a single hole;

    (5) Automatic nitrogen control function, the nitrogen flow rate can be adjusted independently for a single hole (60-600ml/min);
    (6) Food national standard, "Chinese Pharmacopoeia" original design design reflux condenser

    (7) A magnetic stirrer is built in the bottom of the receiving bottle, and the stirring speed can be monotonous for a single group;

    (8) It can be used with our company's nitrogen generator.
