Chinese herbal medicine sulfur dioxide analyzer

Product Usage

The instrument is a new intelligent distillation treatment device that integrates constant temperature heating, automatic control of distillation endpoint, and cooling water circulation according to the laboratory distillation pretreatment operating procedures. This instrument has experimented with functions such as temperature control, automatic anti backflow suction, uniform heating, anti boiling, and intelligent endpoint control. Easy to use, energy-saving and environmentally friendly. After comparing and verifying the distillation recovery rate in the metrology certification laboratory, the results are accurate and reliable, with a recovery rate of over 95%.

Chinese herbal medicine sulfur dioxide analyzerIt can be widely applied to distillation experiments of various chemical laboratories such as pharmaceutical companies, schools, research institutes, factories, and mining enterprises that require the distillation treatment of sulfur dioxide residues in traditional Chinese medicinal materials.

Chinese herbal medicine sulfur dioxide analyzerScope of application:

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.

Compliant with the 2015 edition of the Chinese Pharmacopoeia for detecting residual sulfur dioxide in traditional Chinese medicinal materials and decoction pieces.

Technical Specifications:

The traditional Chinese medicine sulfur dioxide analyzer consists of the following units: four sets of heating control units, one set of built-in cooling water self circulation unit, four sets of nitrogen flow automatic control units, four sets of magnetic stirring control units, timing control unit, and titration unit.

Heating method: using far-infrared ceramic heating furnace, infrared radiation heating (no open flame heating, waterproof)

The whole machine has micro boiling and full boiling adjustment, and automatically adjusts the heating power to prevent explosion boiling during the experimental process.

Heating units: 4, can be single hole single hole

Heating time: 5-8 minutes

Distillation speed: 2-12ml/min (adjustable)

Nitrogen device: The host is equipped with a nitrogen main interface with nitrogen protection function, which can control the nitrogen flow rate (60-600ml/min) through a single hole. After the experiment is completed, the nitrogen can be automatically turned off.

Control mode: Distillation time can be set simultaneously, heating will automatically stop, automation level, no need for manual supervision.

Single hole power: 0-500W (single furnace, adjustable)

Total power: 0-2500W (adjustable)

Cooling method: Closed internal circulation reflux system, no need for external cooling water source, built-in cooling water tank, compressor cooling and cooling internal circulation system, suitable for large-scale work, with excellent condensation effect.

Time control: 0-200min (adjustable), can automatically stop working by setting the distillation time. One click water tank adds water, reaches the liquid level, beeps an alarm, and automatically stops adding water.

Distillation flask specification: 1000ml X4

1. Receiving bottle specification: conical bottle

Working conditions:

Power supply: AC 220V, 50Hz

Environmental temperature: 10-35 ℃

Environmental humidity:<60%

Magnetic stirring control unit:

An independent built-in magnetic stirring device should be installed in the receiving area of each distillation unit, and the stirring speed can be adjusted by an incremental encoder.

Titration unit: The host should be equipped with an independent titration butterfly clip for easy fixation of the burette for titration.

Timing control unit: According to the pharmacopoeia method, each distillation unit should be equipped with an independent timing control device, which can set the working time to 0-200 minutes. After the working time is set, it will automatically count down, and the power will automatically turn off when the timing is over.
