High-pressure digestion tanks for heavy metal detection in the food and drug industry, also known as autoclaves, high-pressure digestion tanks, sample dissolvers, pressure-dissolving bombs, and stuffy tanks , digestion tank, polytetrafluoroethylene high pressure tank. Our company's digestion tanks have solved the customers' problems of large quantity, high requirements, small size and difficulty in digestion during the digestion process.
Specialized for testing in the food and drug industry
High pressure digestion tank.
High-pressure digestion tanks are used for detection of heavy metals lead, chromium, cadmium, nickel and mercury
and sample pretreatment.
In addition: According to the specific requirements of the experiment, Nanjing Ruinike Technology has also independently developed an imported polytetrafluoroethylene
inner cup
that can withstand higher temperatures, is more resistant to penetration, and is more resistant to deformation. As well as more corrosion-resistant alloy outer tanks, digestion tanks with anti-corrosion coatings, double-layer inner cups, etc. Such as
Taiyuan City, Shanxi ProvinceD, Xinzhou City, Shanxi ProvinceD, Zhongshan City, Guangdong ProvinceD, Nanshan District, Shenzhen City, Guangdong ProvinceD, Nanning City, Guangxi ProvinceD, Beihai City, Guangxi ProvinceD,
Guangxi Zhuang Autonomous Region The feedback results from the Institute of Food and Drug Control, Beijing Institute of Botany, Chinese Academy of Sciences, Nanjing Soil Research Institute, Chinese Academy of Sciences, Shanghai Silicate Research Institute, Chinese Academy of Sciences, Nanjing University, Qingdao CTI, Beijing CTI, and Shanghai CTI have been excellent.
Working principle: High-pressure digestion tanks for heavy metal detection in the food and drug industry
Use the environment of the high-temperature and high-pressure sealing system (strong acid and strong alkali) in the tank to achieve the purpose of quickly digesting insoluble substances, which can make the digestion process faster. In order to shorten the time, minimize the volatilization loss of the component being measured, and improve the accuracy of the measurement, it 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 (M), atomic absorption and atomic fluorescence. In food, geology, metallurgy, commodity inspection, nuclear engineering and other systems, it can digest pesticide residues, medicines, food, rare earths, etc. , heavy metals such as b, r, Z,,, H, etc. in various organic matter in aquatic products. Sample pretreatment digests heavy metals, pesticide residues, food, sludge, rare earths, aquatic products, organic matter, etc.
The temperature of the high-pressure digestion tank for heavy metal detection in the food and drug industry can reach
℃ and the pressure
in the oven.
Features of high-pressure digestion tanks for heavy metal detection in the food and drug industry
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, which facilitates sample collection after the experiment.
, Safety: Unique design, fine workmanship, there is a vent hole on the top of the cup, high safety factor. Even if the temperature is out of control, only the inner cup will be deformed, but the outer can will not be damaged.
It has high digestion efficiency and strong ability. It can digest many samples that are difficult to digest by traditional methods and has wide adaptability.
, The element blank value of the inner cup is low, which improves the accuracy and precision of analysis, and reduces the work intensity and environmental pollution
. The inner cup/outer tank is sequentially numbered to facilitate equal opportunity use.
, low cost and easy to use. The investment in the early stage and later stage is very small, the operation is easy, the operator requires almost no training before use, and the maintenance is simple.
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, lower background guarantee, and higher use temperature.
The selected materials for the inner and outer tanks, years of production experience, recognition by many users, quality assurance, and trustworthy.

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 d, H, b, r, and Z.
Our company’s domestically exclusively developed imported polytetrafluoroethylene inner cup
Characteristics
The inner tank is made of high-purity experimental grade imported enhanced modified M material
Compared with: In addition to all the advantages of M, it also has some improved characteristics: lower background guarantee, better resistance to deformation, penetration resistance, and recoverability under high temperature and pressure, and its appearance is closer to jade white
. The maximum operating temperature is d, and the limit can even reach
. Special R&D and production technology ensures the smoothness of the extra-long tanks of special manufacturers (such as M). The inner tanks of microwave digestion instruments of various manufacturers and specifications can be customized and matched with the original factory. The microwave digestion instrument is used
. It is processed by a special process to optimize the processing technology to ensure an extremely low background value (blank value). The manufacturer's processing technology can also affect your experimental results
. For imported microwaves The inner tank matching the digestion instrument is especially the M inner tank which is widely used
. The processed inner cup can be used with other instruments. The experimental data of the product is as good as that obtained from the original import
. Various models of matching M microwave digestion are provided. The inner tank used by the instrument is all made of M material, the lid is made of transparent material, the tube body and gasket are all made of M material, and all materials are available for customers to choose
The only company that can customize the standard equipment of each manufacturer Inner tank, at the same time we promise that the product quality is consistent with the original factory and has the highest cost performance.
Advantages and disadvantages of three commonly used methods for sample pretreatment
Advantages of high-pressure digestion method
: safety, low initial investment, simple equipment, easy operation, small amount of sample and reagents, low blank value, avoid Contamination, safe and thorough sample processing, high accuracy, and can process samples in large batches
Limitations
: Slightly longer sample processing cycle, uncontrollable temperature and pressure, simple appearance
Advantages of room temperature digestion method
/>: Low investment, simple equipment, easy operation, large amount of reagents, average accuracy, short working cycle, large batch processing of samples
Limitations
: Easy to stain, pollute the environment, and harmful to operators Healthy, poor precision. Slightly more reagents are used, and it has limitations for some insoluble samples
