Application Description

Can be used for pre-treatment of sulfur dioxide residue detection in traditional Chinese medicinal materials and decoction pieces according to the methods specified in the Chinese Pharmacopoeia.
2015The Chinese Pharmacopoeia specifies three detection methods for sulfur dioxide: acid-base titration, gas chromatography, ion chromatography, etc. Gas chromatography and ion chromatography have the advantages of high sensitivity and strong specificity, but the expensive equipment is not conducive to the promotion and use of grassroots drug testing systems; The acid-base titration method has the advantages of simple installation and low cost, and is a legal detection method specified in the pharmacopoeia. However, as the pharmacopoeia only describes the glassware device for this method, the purchase, assembly, and implementation of the entire device still need to be continuously improved. For example: （1）In addition to the glass instrument device, magnetic stirring, electric heating jacket, titration platform, nitrogen device with flow meter, etc. need to be equipped and assembled. Many units feel that purchasing a large number of equipment is cumbersome and difficult to assemble and implement, making it impossible to carry out this testing method; （2）The assembled devices are diverse, and there are problems such as unstable nitrogen flow rate, uneven heating, gas leakage, boiling, and susceptibility to cooling water sources during use, which directly affect the test results due to poor parallelism and low recovery rate;3（.
）The work efficiency is low, and currently the equipment adopts a single unit, making it difficult to process multiple samples simultaneously. It is time-consuming and laborious to inspect multiple batches of medicinal materials simultaneously
Instrument * * Point(1)
Integrated design of heating, distillation reflux, cooling, nitrogen blowing control, magnetic stirring, and receiving;(2)
Closed cooling water automatic cooling and circulating reflux device, no need for external tap water cooling, energy-saving and consumption reducing;(3)
Using far-infrared ceramic heating devices instead of ordinary electric furnaces or electric heating sleeves is more energy-efficient, has good waterproof effect, and is resistant to acid and alkali corrosion;(4)4Can do it once
Sample group, heating power can be adjusted through a single hole (knob type);(5)Additional nitrogen protection function, nitrogen blowing flow can be independently adjusted through a single hole（60-600ml/min
）；(6)
Original design of reflux condenser tube in the Chinese Pharmacopoeia(7)
The bottom of the receiving bottle is equipped with a magnetic stirrer, and the stirring speed can be monotonous for a single group;* ST107-1RW
For the high-end version, the following new features have been added:① Different cooling methods: using a compressor+
Dual cooling mode with air cooling, 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;
③ Added automatic timing function, according to pharmacopoeia requirements, the instrument can automatically * * heat up and stop automatically when the time is up;
④ Add a micro boiling heating system to make the sample heated more evenly and the detection structure more reliable

Applicable units and testing items:

Units at all levels of traditional Chinese medicine inspection and testing, traditional Chinese medicine research and development production enterprises, and traditional Chinese medicine that require testing for sulfur dioxide residue in traditional Chinese medicine, medicinal materials, and decoction pieces
