---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.

Advantages gathering

Buchner Funnel with Filter Bottle PTFE Filter Device Pharmaceutical Factory
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.

  • Acid purifier is the equipment used to purify acid in laboratory work in order to avoid the poor purity of acid, which is easy to cause the deviation and error of analysis results.The purity of acid is substantially important in trace-element and ultra-trace element analysis. The higher the purity, the lower the background.
About Us
  • Overview
    Nanjing Binzhenghong Instrument Co., Ltd. was established in the early 1970s. In the mid-1980s, it jointly developed high-tech PTFE products with Shanghai Plastics Research Institute.It is a professional manufacturer of high-quality laboratory Teflon utensils and instruments in China that "develops, customizes, and sells".
    We provide whole-process solutions for "elemental analysis" experiments.

    We have always been adhering to the vision of "making sample pretreatment no longer difficult", and will continue to challenge "the lowest background value of trace analysis containers".

    In the past few decades, our products have been affirmed by many customers in the industry (such as CUG, IGCAS, SGS, etc.), and we will sincerely look forward to cooperating with you now and in the future!
