Graphite Automatic Digestion Furnace

Advantage:

1. This digestive system is a sample processing system designed with the curved heating digestion furnace 

as the main body, with exhaust gas collection and exhaust gas neutralization. This system realizes one-click 

completion from 1 sample digestion → 2 exhaust gas collection → 3 exhaust gas neutralization treatment → 4 digestion

 to stop heating → 5 digestion duct and heating body separation and cooling to be used, realizing the sample automate

 the digestion process, improve the working environment, and reduce the work intensity of operators.

2. Test tube bracket in place detection: the test tube bracket is not placed or the system alarm is not in place, 

preventing equipment damage caused by no sample or wrong placement of the test tube operation.

3. Anti-fouling tray and alarm system: Anti-fouling tray can prevent the acid solution of the exhaust gas collection 

port from polluting the operating table or other environments. If the tray is not removed, the operating system 

alarm and stops running.

4. The digestion furnace is a sample digestion and conversion equipment developed according to the principle 

of classical wet digestion. It is mainly used in agriculture, forestry, environmental protection, geology and petroleum, 

chemical industry, food and other departments, as well as higher education institutions and scientific research depar

tments before the chemical analysis of plants, seeds, feed, soil, ores and other samples. It is the best supporting product

 of Kay's nitrogen analyzer.

Dissolving device:

1. The graphite heating module has good uniformity, small temperature buffer, and the design 

temperature is as high as 550 ℃.

2. The aluminum alloy heating module has a fast heating, long service life and a wide range of 

applications. The design temperature is 450 ℃.

3. The temperature control system adopts a 5.6-inch color touch screen, Chinese and English 

conversion, simple operation.

4. The input of the formula program adopts the table format fast input method, which is logically clear, 

fast and error-pronable.

5. 0-40 segment programs can be selected and set at will.

6. Dual modes of single-point heating and curve heating can be selected at will.

7. Intelligent P, I, D self-rectification temperature control has high accuracy, reliability and stability.

8. Segmented power supply and anti-power restart functions can avoid potential risks.

9. Equipped with overheating, overvoltage and overcurrent protection modules.

Exhaust gas collection device:

1. The sealing cover is made of polytetrafluoroethylene, which is resistant to high

 temperature and resistant to strong acids and alkalis.

2. It is designed as a conical plus flat cover structure, and each sealed cover weighs 35 g.

3. The sealing method adopts gravity natural sealing, which is reliable and convenient.

4. The collection pipe collects acid gas deep into the pipe, which is highly reliable.

5. The shell is welded by 316 stainless steel plate, which has good anti-corrosion performance.

Neutralizer:

1. This product is an acid and alkali neutralization equipment with its own negative pressure pump. 

The pump has a large flow rate, long life and is convenient to use.

2. The three-level absorption of alkali, distilled water and gas ensures the reliability of excluding gases.

3. The instrument is simple to use, safe and reliable.
