Product Details
Introduction:
The main principle is to process Chinese medicinal materials by distillation according to the detection methods provided in the pharmacopoeia. After acid treatment, the sulfite series substances in the sample are converted into sulfur dioxide, which is then carried into an absorption bottle containing hydrogen peroxide with nitrogen gas flow. The hydrogen peroxide oxidizes it into sulfate ions, and the acid-base titration method is used to determine the residual sulfur dioxide in the medicinal materials and decoction pieces. On the basis of strictly following the requirements of the pharmacopoeia, this product integrates functions such as heating, distillation, water circulation, and nitrogen blowing into one, and can provide processing of 3-5 samples (blank samples, parallel samples) simultaneously, greatly improving the accuracy of detection data and reducing working time.
Compliant with standards:
The sulfur dioxide distiller series products are used in accordance with the provisions of General Rule 2331 * * in Part 4 of the Pharmacopoeia of the People's Republic of China to determine the residual amount of sulfur dioxide in medicinal materials or decoction pieces that have been fumigated with sulfur
Product Usage:
This instrument is mainly suitable for various traditional Chinese medicine production enterprises, Chinese medicine research institutes, as well as food production enterprises related to sulfur fumigation, etc., and is used for routine determination of sulfur dioxide residue.
Product principle:
The sulfur dioxide distiller mainly consists of a heating module, a distillation module, a cooling circulating water module, and a nitrogen blowing module. The heating module is equipped with high, medium, and low heating rate control functions, which can achieve a control panel for heating efficiency; The distillation module is made of high borosilicate material, which has good heat resistance and is sturdy and durable; The cooling water circulation system can choose an external cooling water circulation machine (optional built-in) to ensure cooling effectiveness. The nitrogen blowing module can be externally connected to a nitrogen generator or nitrogen steel cylinder, and is equipped with a high-precision gas flow meter to strictly control the nitrogen blowing rate

Product description of low-temperature constant temperature bath:
Low temperature constant temperature bath is widely used in research departments such as petroleum, chemical industry, electronic instruments, physics, chemistry, bioengineering, medicine and health, life sciences, light industry and food property testing and chemical analysis, as well as in higher education institutions, enterprise quality inspection and production departments. It provides users with a controlled and uniform temperature field source for constant temperature experiments or testing of experimental samples or produced products. It can also be used as a heat or cold source for direct heating or cooling and auxiliary heating or cooling.
Main features:
1. The body shell adopts mirror anti-aging electrostatic spray painting technology, and the inner tank surface is made of S304 stainless steel, which is clean, hygienic, beautiful, and corrosion-resistant.
2. Temperature control technology, equipped with standard PT100 and electronic components.
3. The software system facilitates the correction of errors between the displayed temperature and the actual temperature, with a temperature correction resolution of 0.01 ℃, making the displayed temperature value accurate and error free.
4. Equipped with over temperature protection, over temperature alarm, can set the over temperature alarm temperature, and automatically cut off the load when over temperature occurs.
5. The intelligent software has strong temperature stability, and the PID can automatically adjust the matching parameters according to different media. Special users can also manually readjust the parameters.
6. Use software to digitally lock the control system's various settings to avoid accidental operations by unrelated personnel, and ensure that the experimental data is correct and error free.
7. Accurate temperature control ensures rapid and stable temperature inside the work tank.
8. Pressing the "Power" button can turn off all functions of the instrument, but the instrument can also display the process of natural temperature rise and fall in the slot.
9. Efficient fully enclosed compressor refrigeration with fast cooling speed and multiple protections such as overheating and overcurrent.
10. Internal and external circulation systems, the internal circulation ensures uniform and stable temperature, and the external circulation pump outputs a constant temperature liquid to establish a second constant temperature field outside the machine. It can also be used as a cold source to cool the experimental container outside the machine.
11. Optional options include: upgrading temperature control accuracy to 0.001 degrees, equipped with magnetic stirring function, and horizontal low-temperature constant temperature bath.
