---Microwave digestion vessels

As an efficient sample pretreatment method, microwave digestion has the advantages of fast heating speed, uniform heating, less reagent consumption, low blank space, energy saving and high efficiency compared with traditional electroplate digestion. Especially in the analysis and detection of volatile elements can well maintain the integrity of the sample, with a high sample recovery. At present, microwave digestion apparatus has been widely used in food, textile, geology, metallurgy, plastics, coal, cosmetics, petrochemical, biological medicine, environmental monitoring, sewage treatment, battery manufacturing and other fields.

we can provide the microwave digestion inner vessels suitable for CEM, Milestone, ect. the experimental results can compared with the original factory.

1. It is suitable for pre-digestion treatment of various laboratory samples and provides efficient sample preparation for the analysis of major and trace elements in experimental samples.

2. Suitable for pre-extraction and analysis of organic pollutants and pesticide residues in laboratory samples.

3. General requirements for instrument accessories: able to quickly process 40 samples of food, medicine, health care cosmetics, sewage sediments, atmospheric environment, geology, mining, metallurgy and other related samples in the same batch.

4. The wall thickness of the inner tank is uniform, and the error does not exceed 0.02mm, ensuring uniform microwave energy field and ensuring that the sample is fully digested.

5. The material density is 2.17~2.25g/cm3, and the average particle size is 25um, ensuring uniform microwave energy field and ensuring that insoluble samples are fully and evenly digested.

6. Material hardness is 59 N/mm2, tensile strength, elongation at break (tested with 0.2 film): 40N/mm2 and 650%, compression deformation: 9% (15N/mm, 2175psi, 100 hours), resistance The flammability is greater than 95%, the dielectric strength (tested with 0.2 film) is 104~105KV/mm, the volume resistivity is 1010~1018Ω.cm and many other safety indicators ensure the safe use of the inner tank.

7. The roughness of the inner and outer walls is lower than Ra 3.12~3.36um, which is easy to clean, high work efficiency and extends the service life of the inner tank.

8. Volatile organic compounds (target compounds) are precipitated. During high-temperature use, no other substances are precipitated and do not interfere with the digestion of target compounds;

9. The total product weight is 125±2 grams, the capacity is 55ml±1%, the temperature resistance is: 260℃, the surface pressure is: 2200psiMax, the heating rate is ≤5℃/min

10. The materials are enhanced TFM (lining + plug) and enhanced PFA (top cover)

11. Applicable equipment, CEM–MARS series

A Buchner funnel is an instrument used in laboratories for filtration using vacuum or negative pressure suction. The Buchner funnel can replace the ceramic Buchner funnel to avoid fragmentation. The Buchner funnel made of polytetrafluoroethylene has strong resistance and can be filtered using vacuum or negative pressure suction. It can also be matched with a suction filter bottle for use in crystal or inorganic preparation. Reduced pressure filtration of coarse particle precipitation can prevent corrosive solvents from splashing out.
