MWD-700 Closed Intelligent Microwave Digestion Instrument

Product Name: MWD-700 Sealed Intelligent Microwave Digestion Instrument

Product model: MWD-700

Microwave digestion, as an efficient sample pretreatment method, has the advantages of fast heating speed, uniform heating, less reagent dosage, low blank, energy saving and high efficiency compared to traditional electric plate digestion. In the analysis and detection of volatile elements, it can maintain the integrity of the sample well and has a high sample recovery rate. At present, it has been widely used in fields such as food, textiles, geology, metallurgy, plastics, coal, cosmetics, petrochemicals, biomedicine, environmental monitoring, sewage treatment, battery manufacturing, etc.

Instrument features and functions

◆ Zero consumables whole machine design: From the perspective of users, the traditional design method of consumables such as explosion-proof membranes, elastomers, sealing bowls, and sealing rings in microwave digestion instruments has been abandoned. New design concepts have been applied to innovate and develop a zero consumables microwave digestion instrument, which solves the problems of difficult declaration, insufficient funds, and long cycles for users to purchase consumables and accessories in the future;

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

◆ Self recovery compound sample digestion tank: The design of the self recovery compound structure enables the sample digestion tank to automatically restore its sealed state and continue to work after overpressure relief during the digestion process. This provides a guarantee for avoiding batch sample scrap and reducing solvent waste rate;

◆ Tank Material: The sample digestion tank is processed using 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, making it safe and durable;

◆ Temperature pressure dual monitoring/protection system: Mid infrared temperature measurement technology can measure the true temperature of the sample solution in the digestion tank. Combined with multi fiber non-contact scanning pressure measurement, it not only achieves complete isolation between the sample and the temperature pressure monitoring/protection system, avoiding cross contamination between samples, but also realizes the dual monitoring function of individual temperature and pressure measurement for all sample digestion tanks, and has overvoltage and temperature overheating protection functions;

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, and extends the service life of the motor;

◆ External 8-inch color touch screen, which can simultaneously display temperature, pressure, time, and microwave power curves in real time. It also adds a real-time output display window for pressure and temperature 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 set the relevant parameters (temperature, 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 (temperature, pressure, time, and microwave power) during program operation; 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 refer to the analysis and handling methods of related problems, saving time from 'reporting to the manufacturer, understanding the situation, phone guidance or on-site maintenance', improving work efficiency, and bringing convenience to operators during use;

Standard output port: can be connected to computers and other devices;

◆ 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 regulation method: Adopting frequency conversion resonance or non pulse (optional) continuous microwave intelligent regulation method, the microwave output is stable, and users can adjust it freely between 0-3000W according to their needs;

Multiple active and passive safety protection functions: dual safety protection door, temperature monitoring function, over temperature and sudden temperature rise protection function, pressure monitoring function, over pressure and sudden pressure rise protection function, instrument fault monitoring prompt function, door opening pause protection function, abnormal noise monitoring function, emergency stop button protection, etc; Optional remote control function.
