Digestion tank
1. Introduction:
Nanjing Ruinike Technology’s special high-pressure digestion tank for detection of heavy metal element lead in food is also called They are high-pressure digestion tanks, sample dissolvers, pressure dissolve bombs, pressure digestion tanks, pressure digesters, digestion tanks, and polytetrafluoroethylene high-pressure tanks. -- (Wen Li-) Our company's digestion tanks have solved the problems of customers with large quantities, high requirements, small size and difficulty in digestion during the digestion process.
Lead: It is toxic to all tissues of the human body. The poisoning route can be through inhalation of its vapor or dust through the respiratory tract, and then the phagocytes in the respiratory tract quickly bring it to the blood or absorb it into the blood circulation through the digestive tract, causing poisoning. Poisoners generally have a history of exposure to lead and lead compounds. Oral administration - grams can cause poisoning and can lead to death.
Excessive amounts of some trace elements in daily life are also harmful to the human body. For example, different units such as lead, cadmium, chromium, etc. also choose different methods for digestion of heavy metals. Some laboratories use microwave digestion equipment. However, according to the national standard sample digestion, the sample volume of lead digested by the microwave digestion equipment cannot be greater than . And the loss is large. At the same time, the digestion is not complete. When the sample amount is large, the experimenter finds it difficult. Therefore, Nanjing Ruinike's high-pressure digestion tank solves this problem and solves the confusion of the laboratory, such as: Taiyuan City, Shanxi Province D, Xinzhou City, Shanxi Province D, Zhongshan, Guangdong Province City D, Nanshan District, Shenzhen City, Guangdong Province D, Nanning City, Guangxi Province D, Beihai City, Guangxi Province, Guangxi Zhuang Autonomous Region Food and Drug Inspection Institute, Beijing Institute of Botany, Chinese Academy of Sciences, Nanjing Soil Research Institute, Chinese Academy of Sciences, Shanghai Ceramic Institute, Chinese Academy of Sciences, Nanjing University, Qingdao CET, Beijing CET, Shanghai CET, etc. have received very good feedback.
The temperature of the high-pressure digestion tank in the oven can reach ℃ withstand pressure. The inner cup is made of experimental-grade high-purity polytetrafluoroethylene. The blank value of metal elements is low. The content of lead and uranium is less than 100%. No dissolution and precipitation. No recycled materials are added. The outer tank is made of national standard stainless steel. The inner cup can also be equipped with an acid catcher. In the later stage, acid removal and digestion experiments will be done.
Selected materials, no recycled materials added, clean processing environment, optimized processing technology to ensure extremely low background.
2. Features of the high-pressure digestion tank:
, Good sealing: the inner cup of the high-pressure digestion tank has a concave and convex tongue and groove design, and the inner cup lid has a pointed bottom design to facilitate sample collection after the experiment
, safety: design The unique workmanship and the vent hole on the top of the cup have a high safety factor. Even if the temperature is out of control, the inner cup will only deform and the outer jar will not be damaged.
It has high digestion efficiency and strong ability to digest many samples that are difficult to digest with traditional methods. It has wide adaptability.
The low element blank value of the inner cup improves the accuracy and precision of analysis and reduces work intensity and environmental pollution.
The inner cup/outer can are sequentially numbered to facilitate equal opportunity use.
, low cost and easy to use. There is very little investment in the early and late stages, and it is easy to operate. The operator requires almost no training before use and is simple to maintain.
The inner cup can be changed to imported polytetrafluoroethylene (the material of the inner tank of the microwave tank), which is more resistant to penetration and deformation and has a lower background to ensure a higher use temperature.
The selected materials for the inner and outer tanks, many years of production experience, and the quality assurance recognized by many users are trustworthy.

3. Work Principle:
The high-pressure digestion tank uses the high-temperature and high-pressure sealing system (strong acid and strong alkali) environment in the tank to achieve the purpose of quickly digesting insoluble substances, which can greatly shorten the digestion process and reduce the volatilization loss of the measured components. Minimizing the accuracy of the measurement is a powerful assistant for digesting samples when measuring trace elements and trace elements.
It is widely used in sample preprocessing for chemical analysis methods such as spectrum mass spectrometry (-), atomic absorption and atomic fluorescence. It is used in food, geology, metallurgy, commodity inspection, nuclear engineering and other systems to digest pesticide residues, medicines, food, rare earths, water, etc. Heavy metals such as, Sample pretreatment digests heavy metals, pesticide residues, food, sludge, rare earths, aquatic products, organic matter, etc.

Inner cup
Characteristics: -- (Wenli-)
The inner tank adopts high-purity experimental grade imported enhanced modification Processing materials
Compared with: In addition to all the advantages, it also has some improved characteristics: it has a lower background to ensure resistance to deformation, penetration resistance, and recoverability under high temperature and pressure, and its appearance is much closer to Jade white
, the maximum operating temperature is the limit or even up to
, the special R&D and production process ensures the smoothness of the extra-long tanks of special manufacturers (such as), and can be customized to match the original factory of the inner tank of the microwave digestion instrument of various manufacturers and specifications. The use of microwave digestion equipment
, special processing and optimization of processing technology to ensure extremely low background value (blank value). The processing technology of the manufacturer can also affect your experimental results
, supporting imported microwave digestion equipment The inner tank, especially the widely used inner tank
, the processed inner cup can be as good as the experimental data of the general product of its instrument and the original imported one
, and the inner tank used in supporting various types of microwave digestion instruments is provided. All materials are made of transparent materials. The lids are made of transparent materials. The tube body and gaskets are made of natural materials and all materials are available for customers to choose
. We are the only company that can customize the inner tank that comes standard with each manufacturer's instruments. At the same time, we promise that the product quality is consistent with the original factory and has the highest price/performance ratio. .
The high-pressure digestion method is recognized as a standard method by relevant departments in my country, such as,,,,,/,/-, etc. The United States also stipulates that this method is the standard decomposition method of samples for the determination of elements such as , , , , , and .
Advantages and disadvantages of three commonly used methods for sample pretreatment:
