The Meicheng DR-15N graphite digestion device is a specialized instrument used for batch pretreatment of chemical analysis samples. The product design is based on the principle of wet digestion and adopts mature technology that is widely used. It has the advantages of fast digestion, high efficiency and energy saving, safety and reliability, simple operation, and easy maintenance.

The Meicheng DR-15N graphite digester can process 15 samples simultaneously. The high-purity graphite surface is treated with 6 layers of Teflon spray coating, providing excellent corrosion resistance. In terms of temperature control, closed-loop automatic control technology (PID) is adopted to achieve fast, uniform, stable and efficient sample processing, which complies with EPA and national industry standards and specifications,The size of the digestion hole can be customized according to customer requirements.

The Meicheng DR-15N graphite digester is an ideal supporting product for laboratory microwave digestion pretreatment and acid treatment, and can also be used for sample pretreatment of analytical instruments such as AAS, ICP, ICP-MS. Compared with traditional methods, the energy-saving and acid saving effects are extremely significant, and it can replace electric furnaces, flat heaters, and water bath heaters, making it an ideal laboratory supporting product for the new generation.

MeichengDR-15N graphite digester is widely used in medical and health, food and beverage, chemical testing, agriculture, forestry, animal husbandry and fishery industries, pharmaceutical industry, cosmetics industry and chemical industry. Especially for the pretreatment of easily soluble chemical samples under normal pressure, it has the performance of traditional methods.

Instrument characteristics

1)Heating evenlyHeating element selected with high thermal conductivity and durabilityWarm high-purity graphite ensures uniform temperature in the dissolution pores. When dissolving multiple samples, it can ensure that each sample has the same reaction temperature,At 150 ℃, the temperature difference between holes is ≤ 1 ℃

2)Strong corrosion resistanceThe graphite surface is sprayed with 6 layers of DuPont Teflon, which is easy to clean, heat-resistant, corrosion-resistant, and can be used for a long time in strong acid and alkali environments

3)Accurate control： PID digital temperature control system, temperature control accuracy can reach ± 0.1 ℃

4)Program controlled heating:Using infrared heating method, the heating rate can be adjusted arbitrarily, and the temperature holding time can be controlled. The highest temperature can reach 260 ℃

5)Security guarantee:After heating is completed, the program automatically stops without any safety hazards

6)A wide range of applicationsCan be used for routine heating of laboratory samples, can accurately control sample digestion, and can quickly remove acid from samples after microwave digestion

7)Easy to replace componentsThe whole machine adopts a modular design, and users can replace the corresponding components according to the instructions, saving time and effort
