microwave digester has been used in food, medicine, textile, plastics, geology, metallurgy, coal, biomedicine, petrochemical industry, environmental monitoring, sewage treatment, cosmetics and other fields, but the inner tank of imported microwave digester is really troublesome in terms of processing cycle and product price, Our factory can process various types of microwave digester inner cans and related shelves, turntables, plugs and gaskets

The microwave digestion tank is composed of a shell (sheath) and an inserted digestion tank
Such a combined tank can be separated
The combined tank is generally composed of shell, frame (middle layer) and inserted digestion tank, and some combined tanks do not use the middle layer
Shell materials include composite fiber, peek, high temperature ceramics and ultem-100 (ULTEM materials have basically been eliminated)
The frame is mainly made of PFA and high-strength engineering plastics
The inserted digestion tank is in direct contact with the sample and acid
The performance of acid resistance, temperature resistance and high pressure resistance should be considered first
There are generally four kinds of materials for the inserted digestion tank (or integrated digestion tank), including PTFE, TFM, PFA and quartz
The first three belong to fluoroplastics
Quartz digester can not be used alone, but should be sheathed
Compared with the three fluoroplastics, there is no doubt that TFM is a good digestion material
Therefore, at present, the plug-in digestion tanks of high-pressure digestion tanks of imported microwave digestion systems are made of TFM
PFA and PTFE can only be used as medium and low pressure digestion vessels

The inner cans of microwave digester that can be customized by our factory are as follows:
It is suitable for American CEM, melstone, antonpa, Jena, Shanghai Xinyi, Shanghai Xintuo, Shanghai Yiyao, Beifen Ruili, Beijing Xianghu, Shandong Haineng, etc

3、 TFM material performance description (its advantages over PTFE)
1
Deformation resistance, penetration resistance, good recoverability and slightly better transparency under high temperature and high pressure
2
Special process finishing, good sealing performance
3
High surface finish, smooth inner and outer walls, no water hanging, easy to clean
4
Strong acid and alkali resistant organic solvents
5
It has low metal dissolution and precipitation, anti pollution, and does not adhere to samples
It is suitable for trace, ultra trace and micro analysis

4、 What makes us special:
1
The microwave cans processed by our factory can match the original instruments, and the cover and body are matched without any dimensional error;
2
The inner tank cover of the digestion instrument produced by us is made of PFA material, and the tank body and spring pad are made of TFM material;
3
The experimental data is no less than the original factory, and the cost is low, which greatly reduces the cost of purchasing consumables by many scientific research institutions;
4
Selected materials without adding recycled materials, clean processing environment, optimized processing technology and ensured very low background;
5
TFM is resistant to high and low temperature, sometimes 300 ℃, and has the characteristics of low blank value, good deformation resistance, penetration resistance, strong recovery under high temperature and high pressure, etc

5、 Explain
TFM belongs to modified PTFE, melting point 320-340 ℃
In addition to all the advantages of PTFE, there are some noteworthy characteristic improvements: less deformation and permeability at high temperature and high pressure, better heavy pressure recovery at high temperature and high surface finish
Although PFA is translucent, its service temperature is not as good as PTFE
Therefore, TFM is the material of digestion container
PTFE digestion tank can only do medium and high pressure, while TFM digestion tank can do ultra-high pressure microwave digestion

1
It is applicable to the digestion pretreatment process of various samples in the laboratory, and provides efficient and high-quality samples for the analysis of major and trace elements in experimental samples
