Description of use It can be used in the pre-treatment of the detection of sulfur dioxide residues in traditional Chinese medicinal materials 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 and use 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 is also necessary to be equipped with a magnetic stirring, an electric heating mantle, a titration platform, a nitrogen device with a flow meter, etc., and to be 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 air 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. Simultaneous inspection of secondary medicinal materials is time-consuming and laborious.
(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) There is a built-in magnetic stirrer at the bottom of the receiving bottle, and the stirring speed can be single group and monotonous;
* ST107-1RW is a high-end version, and the newly added functions are as follows:
① Different cooling methods: compressor + air cooling dual cooling mode, good cooling effect, suitable for continuous batch processing of samples, not affected by room temperature;
② Newly added anti-dry burning design, thermal overload protection, to prevent the flask from cracking and drying out;
③Added the automatic timing function, according to the requirements of the Pharmacopoeia, the instrument can automatically count down and heat, and it will automatically stop when the time is up;
④The newly-added micro-boiling heating system makes the sample heated more evenly and the detection structure is more reliable
