Nanjing Ruinike high-pressure digestion tank dedicated for dairy product testing is also known as autoclave, high-pressure digestion tank, sample dissolver, pressure dissolve bomb, stuffy tank, digestion tank, high-pressure polytetrafluoroethylene Can. -- (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.
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, penetration and deformation. As well as more corrosion-resistant aluminum alloy outer tanks and digestion tanks with anti-corrosion coating double-layer inner cups, etc. Such as: Anhui Danuo Dairy Co., Ltd., Hebei Handan Fuyang Dairy Co., Ltd., Danyang Kangli Dairy Products Co., Ltd., Zhangjiakou Great Wall Dairy Co., Ltd., Qinghai Xining Wahaha Qili Beverage Co., Ltd., Inner Mongolia Yili Industrial Group Co., Ltd., Foshan Nanhai District Buffalo Milk Research and Development Co., Ltd., Foshan Nanhai District Lishui Kanghua Dairy Beverage Factory, Wangwang Group Xinjiang Shihezi Industrial Park, etc. have received excellent feedback.
Working principle: The special high-pressure digestion tank for dairy products uses the environment of the high-temperature and high-pressure sealing system (strong acid and strong alkali) in the tank to achieve the purpose of rapid digestion of insoluble substances, which can greatly shorten the digestion process and make the tested group Minimizing the volatilization loss of parts and improving the accuracy of 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.
The temperature used in the high-pressure digestion tank oven for dairy product testing can reach ℃ pressure
.
In January 2017, the General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China put forward new requirements for dairy and infant formula milk powder enterprises based on the current quality and safety of domestic infant dairy products. That is, the above-mentioned enterprises must resubmit production license applications in accordance with relevant document requirements and submit the Initially re-examined. Compared with the original rules, the new rules have added a number of self-inspection items especially for infant formula milk powder products, including: melamine, harmful heavy metal contamination elements, nutrients, pesticide residues, fatty acids and trans fatty acids, vitamins, etc.
Features of the high-pressure digestion tank dedicated for dairy product testing:
.Safe design, passive temperature control turns into active pressure control. There is no danger even if the temperature goes out of control.
.High digestion efficiency and strong ability to digest many samples that are difficult to digest with traditional methods and wide adaptability.
.The high-pressure digestion tank has good sealing performance and the inner cup has a concave and convex tongue and groove design.
.The low element blank value of the inner cup improves the accuracy and precision of analysis and reduces work intensity and environmental pollution.
.The outer tank and inner cup have corresponding numbers to facilitate experiments.
. 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
(Microwave tank inner tank material)
More resistant to penetration and deformation, lower background ensures 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.
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 .

Features: --(Wenli-)
The inner tank is made of high-purity experimental grade imported enhanced modified materials< br/> Compared with: In addition to all the advantages, it also has some improved characteristics: it has a lower background to ensure better resistance to deformation, penetration resistance and recoverability under high temperature and high pressure, and its appearance is closer to jade white< br/>, the maximum operating temperature is the limit or even up to
, special R&D and production technology ensures the smoothness of the extra-long tanks of special manufacturers (such as), the inner tank of the microwave digestion instrument of each manufacturer can be customized to match the original microwave digestion instrument Use
, special processing and optimized processing technology to ensure extremely low background value (blank value). The manufacturer's processing technology can also affect your experimental results
, the inner tank matching the imported microwave digestion instrument 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 all made of materials The lid is made of transparent material, the tube body and the gasket are made of all materials 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.
Advantages and disadvantages of three commonly used methods for sample pretreatment:
Advantages of high-pressure digestion
: safety, low initial investment, simple equipment, easy operation, less sample and reagent consumption, low blank value, Avoid contamination, sample processing is safe and thorough, high accuracy, and can process samples in large batches
Limitations
: The sample processing cycle is slightly longer, the temperature and pressure cannot be controlled, and the appearance is simple
Advantages of room temperature digestion method< br/>: Low investment, simple equipment, easy operation, large amount of reagents, average accuracy, short working cycle, and can process large batches of samples
Limitations
: easy to stain, pollute the environment, and damage the operation Personnel health, poor precision, slightly more reagents, limitations for some insoluble samples
Advantages of microwave digestion
: safety, temperature and pressure control, high efficiency in small batches, samples and reagents Less dosage, low blank value, avoid contamination, high accuracy, high degree of intelligence
Limitations
: Large investment in the early and late stages, high requirements for operators, limitations for certain samples, and Large loss, incomplete digestion, low working temperature, and inability to achieve maximum temperature and pressure at the same time
