MWD-500 is highly favored by users for its stable performance, convenient operation methods, intuitive human-computer interaction interface, and humanized modular structure design. Suitable for sample pretreatment of analytical methods such as atomic absorption spectroscopy (AAS), ultraviolet visible spectrophotometer (UV Vis), inductively coupled plasma emission spectrometer (ICP-AES), atomic fluorescence spectrometer (AFS), graphite furnace atomic absorption spectrometer (GFAA), X-ray fluorescence spectrometer (XFS), inductively coupled plasma mass spectrometer (ICP-MS), high-performance liquid chromatography (HPLC), etc. At present, it has been applied in fields such as food, textiles, geology, metallurgy, plastics, coal, cosmetics, petrochemicals, biomedicine, environmental monitoring, sewage treatment, battery manufacturing, etc.

Instrument features and functions

◆ Self recovery low consumable digestion tank: The digestion tank eliminates consumables such as sealing bowls and explosion-proof membranes, saving users consumables expenses; The digestion tank can automatically restore its sealed state and continue to work after encountering overpressure relief during the digestion process, which provides a guarantee for avoiding the scrapping of batch samples and reducing the waste rate of solvents used;

◆ Suitable for high-pressure sealed microwave digestion, microwave extraction, microwave synthesis, etc;

◆ Material of digestion tank: The sample digestion tank is processed with modified TFM, and the protective outer tank is made of composite material (PEEK+fiberglass) fused together, which is temperature and pressure resistant, as well as acid, alkali and organic solvent resistant, safe and durable;

Pressure monitoring/protection system: Adopting multi fiber non-contact scanning pressure measurement, it not only achieves complete isolation between the sample and the pressure monitoring/protection system, but also avoids cross infection between samples; And it has achieved the function of individual pressure measurement for all sample digestion tanks, and has overvoltage protection function;

360 ° continuous uniform rotation platform: It realizes the continuous uniform rotation of the digestion tank combination in the same direction inside the furnace cavity, solving the problem of unequal and uneven heating of different tank positions by microwaves; The simultaneous continuous rotation method reduces the impact of reciprocating rotation less than 360 ° on the rotating motor in the market, thereby extending the service life of the rotating motor;

The built-in 7-inch color touch screen can simultaneously display pressure, time, and microwave power curves in real time. It also adds a real-time output display window for the pressure inside a single digestion tank, making the digestion process and changes clear at a glance;

Large capacity memory system: can freely edit, modify, and store 255 types of digestion programs; Each method program can have 10 digestion steps; Users can design the relevant parameters (pressure, time, and microwave power) for each digestion step according to their needs, providing convenience for their use and operation;

Humanized and intelligent software operation interface: equipped with a flip back function, users can also flip back the interface to view relevant parameters (pressure, time, and microwave power) during program operation, designed for humanization and convenience; There is a 'Help Interface' that provides detailed and systematic explanations of various common problems and troubleshooting methods. If operators encounter problems during use, they can quickly and promptly refer to the analysis and handling methods of related problems, saving time from 'reporting to the manufacturer for information' to 'phone guidance or on-site repair', improving work efficiency, and bringing convenience to operators during use;

◆ External emergency stop button: In case of an accident, it can directly and quickly cut off the microwave power supply, ensuring the personal safety of the operator;

Power and power adjustment method: Adopting non pulse continuous microwave intelligent adjustment method, the microwave output is stable, and users can adjust it freely between 0-1000W according to their needs;

Multiple active and passive safety protection functions: dual linkage safety protection door, pressure monitoring function, overvoltage and pressure surge protection function, instrument fault monitoring prompt function, door opening pause protection function, abnormal noise monitoring function, emergency stop button protection function, etc.
