Model: PTH-1B

Acid-base Neutralizing Device is the best for collecting, neutralizing, and filtering acid mist. It consists of a three-level filter. The first stage is achieved by neutralizing the acid mist with a corresponding concentration of alkali solution. The second stage uses distilled water to continue filtering the residual exhaust gas. The third stage is where the residual exhaust gas enters the buffer bottle for buffering. The gas filtered by the third stage can meet the emission standards without causing harm to the environment or facilities, ultimately achieving pollution-free emissions.

Model: PRSJ

Waste Gas Collection Device is a specially designed acid gas collection device for digestion furnaces. It can collect a large amount of acid gas (acid mist) generated during the sample digestion process through this collection device, and then process it through a neutralization device.

Model: PZF-06 /PZF-06A

Automatic Fat Analyzer is designed for fully automatic one-button operation, with easy operation, stable performance and high precision. It has multiple automatic extraction modes such as Soxhlet extraction, thermal extraction, Soxhlet thermal extraction, continuous flow and standard thermal extraction. According to the Soxhlet extraction principle, the gravimetric method is used to determine the fat content in grains, grains, and foods.

Model: ZDDN-9830S

Sulfur Dioxide(so2) Analyzer is a sulfur dioxide measuring instrument designed based on the principle of distillation according to national standards. It can automatically complete reagent addition, distillation, nitrogen blowing and other functions. This product is widely used in basic analysis, technological research and development, quality control and other fields.

Model: ZDDN-9830Y

Automatic Cation Exchange Analyzer is based on the method of "LYT 1243-1999 Determination of Cation Exchange Capacity of Forest Soil". The soil is repeatedly treated with 1mol/L ammonium acetate solution to make the soil saturated with ammonium ions. The excess ammonium acetate is washed away with 95% ethanol, and then Add magnesium oxide for distillation. The distilled ammonia is absorbed with boric acid solution, titrated with standard acid solution, and the soil cation exchange capacity is calculated based on the amount of ammonium ions.
