Food sulfur dioxide distiller

Instrument features:

1. Intelligent microcomputer operation, microcomputer 7-inch color touch screen, display screen fixed in front of the machine, convenient for experimental personnel to operate, friendly and convenient interface, easy for experimental personnel to operate, and can independently set various instrument parameters;

2. Adopting far-infrared radiation heating, it can be switched on and off with a single channel or one button. Temperature dynamic display, heating temperature range: room temperature -650 ℃. Intelligent PID temperature regulation, temperature control accuracy can reach ± 1 ℃.

3. Four/six distillation units, capable of single hole control, can be switched freely during the micro boiling and full boiling experiments, and the micro boiling temperature and full boiling temperature can be set separately.

4. Time countdown. Real time display of remaining time, with an alarm indicating the end of distillation and automatic stop of heating and nitrogen blowing when the set time is reached.

5.Food sulfur dioxide distillerEquipped with 4/6 magnetic stirring channels, the speed can be controlled separately. Each magnetic stirring channel has an independent switch and can be infinitely adjusted, with a stirring speed of 0-1400r/min.

6. Four/six nitrogen blowing units, controlled by independent rotor flow meters, with a flow range of 0-500ml/min (0-2L/min), and automatic pressure relief for overpressure.

7. After the distillation is completed and the instrument automatically stops heating, the anti backflow function is automatically turned on to prevent the absorption liquid from backflow during the cooling process of the flask, which may cause experimental failure.

8. The instrument can be cooled by external tap water, which can automatically start and automatically shut down after a delay, achieving water conservation. Optional high-power cooling water machine.

9. The instrument is equipped with an independent titration butterfly clip, and the fixing rod can be flexibly inserted and removed for easy titration.

10. The body adopts sheet metal spray coating, which is resistant to acid, alkali and organic solvent corrosion. Greatly improve the lifespan of experimental instruments.

11. The instrument adopts a wide range of 24V safe voltage internally, ensuring the absolute safety of experimental personnel.

12. Temperature parameters can be calibrated to improve experimental accuracy.

Instrument usage:

Can be used for the determination of residual sulfur dioxide in food according to GB 5009.34-2022 national food safety standard, in compliance with the first method of the national standard, acid-base titration method.

It 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. It complies with the detection of sulfur dioxide residue in traditional Chinese medicinal materials and decoction pieces in the 2020 edition of the Chinese Pharmacopoeia and is suitable for drug supervision, drug inspection, industry associations, research institutes, universities, and medicinal material enterprises.
