  • Product number



    2016 new, PLC control, built-in compressor plus air-cooled dual cooling mode, the sample is heated micro-boiling control program. Anti-dry protection against short circuits can.


    Upgrade section 107-1, PLC control, touch-screen LCD, anti-dry design, the sample is heated boil control program, the air-cooled general circulation cooling system.

    Completely faithful to the 2015 edition of "Chinese Pharmacopoeia" legal method for detecting the national invention patent technology products, patent No invention: ZL200910019901.4
    2012 annual Jinan independent innovation products (included in the government priority procurement plan)

    Instructions for use may be used to detect <br style="margin: 0px; padding: 0px; list-style: none; color: rgb(71, 71, 71); font-family: Arial, Helvetica, sans-serif; font-size: 12px; white-space: normal; background-color: rgb(255, 255, 255);"/> pretreatment "Chinese Pharmacopoeia" Method of medicines and residual amounts of sulfur dioxide Pieces.
    2015 edition of "Chinese Pharmacopoeia" provides for three detecting sulfur dioxide: acid-base titration, gas chromatography, ion chromatography and the like. Gas, ion chromatography has high sensitivity, specificity and other advantages, but expensive equipment is not conducive to promoting the use of drug testing system of the base layer; acid-base titration with simple means, the advantages of low cost, a method for detecting a predetermined statutory Pharmacopoeia. However, due to the glassware Pharmacopoeia apparatus only describes the method, the entire purchase, assembly and embodiment of the apparatus needs to continue to improve. For example: (1) except glassware means it needs equipped with a magnetic stirring heating mantle, the platform titration, nitrogen gas flow rate meter device or the like is provided and assembled. Many later devices units that many and complicated, difficult to assemble embodiment, the detection method can not be carried out; (2) a wide variety of apparatus assembled, the presence of the nitrogen flow rate is unstable during use, uneven heating, easy to leak, easy to bumping susceptible to affect the cooling water and so on, to bring the respective parallel poor, low recovery phenomena directly affect the test results; (3) low productivity, equipment currently adopt single apparatus, it is difficult to simultaneously process a plurality of samples of the batches times herbs while time-consuming tests.

    Instrument innovation
    (1) is heated at reflux for distillation, cooling, nitrogen purge control, magnetic stirring, receiving six integrated design;
    (2) closed cooling and circulation of cooling water recirculation apparatus for an automatic, no external water cooling, energy saving;
    (3) use of far infrared ceramic heater or an electric heater instead of an ordinary electric furnace jacket, more energy, better waterproof effect acid corrosion;
    (4) a set of samples 4 to do, the heating power may be adjustable hole (knob);
    (5) Additional protection of nitrogen, the nitrogen may be blown into the single flow adjust Kong Duli (60-600ml / min);
    (6) "Chinese Pharmacopoeia" reflux condenser design artwork
    The bottom (7) built-in the receiving flask with a magnetic stirrer, stirring speed may be a single set of monotone;
