MDE-45D  microwave digestion/extraction/synthesis system  a subversion of tradition, is a market-oriented practical compact microwave digester made by Acculab with its over 20 years’ experience; It highlights the company’s three major ideas of product design and also meets users’ needs in “safety”, “durability” and “convenience of operation

• The outer vessel of MDE-45D made by ultrastrength aerospace composite fiber is invincible in anti-explosion, and its performance indicators such as corrosion resistance, high temperature/impact/pressure resistance are far better than that of the widely used modified PEEK engineering plastics vessel (this material is fusible at high temperature, fragile at high pressure and explosive by chemical corrosion). The compressive strength of aerospace composite fiber is up to 10000psi and temperature 500-600°C, fundamentally eliminating safety risks to operator in use.
• Quantified vertical blast/safety bolt design, ensures samples be closed completely and triggers a quantified pressure relief while over pressure; safety bolt (patent) unit, instead of safety membrane and other consumables, ensure the digestion vessel be sealed completely under normal working conditions. And only when the pressure is large enough and may constitute a danger to the safety, the safety bolt will automatically blow out vertically and the cover auto-up to release the pressure, achieving quantified vertical blast pressure-relief to guarantee its well operation. Under normal operation, the safety bolt won’t blow out and requires no replacement. In addition, it is easy for venting to open the cover after completion of digestion.
• The industrial-leading pressure measuring technology by piezoelectric crystal and high-precision Pt sensor temperature measurement and control, through closed-loop control of microwave power by inverter technology, ensures the accuracy of pressure and temperature monitoring and control. The application of patented piezoelectric crystal brings about complete isolation of samples from pressure measurement system in digestion process, thoroughly solving the problems of cross contamination of samples due to commonly used air pipe in market and of the limitation in digestion samples because of low-pressure proof of air pipe

• The Gold Award in Automatic Frequency Control of Non-pulse Microwave Power on BCEIA represents that the company not only achieves the accurate closed-loop control of the temperature and pressure, but also improves the efficiency of microwave transmitter of magnetron, realizing energy saving (37.5 %).

• Sturdy and durable industrial-grade chamber design strengthen its impact resistance; Professional focused microwave design make microwave heating more efficient; Multi-layer chemical resistant coating greatly improves the service life and safety of the system; the popup cushioning explosion-proof sliding chamber door builds a passive safety protection system, easing operation; double-locked self-checking system of the chamber door and the push-type open-door mechanism at the top make the operation simple and easy; efficient exhaust system design achieves fast and safe air-cooled cooling, improving operational efficiency

Microwave Reaction System adopts the international advanced double magnetronFrequency microwave heating system and realizes

the high power microwave balanced magneticField safety heating. Microwave Reaction System has been widely used in food,

textile, plastic, geological, metallurgical, coal, biological medicine, petroleum chemical industry, environmental monitoring,

sewage treatment, battery manufacturing, cosmetics, etc.

Characteristic:

Double magnetron variable frequency control system: It could adjust microwave output continuously.

It makes the microwave field more uniform and more accurate that could ensure the sample digestion is uniform.

The high accuracy pressure sensor could make the pressure control more precise.

7″LCD color touch-screen real time display the temperature and pressure curve.

Built-in method library (50 methods for MRS-45C) and the methods could be programmed.

Feature:

Multiple safety protection function

It has more than ten safety protection measures to ensure experiment safety, including temperature control system,

pressure control system, and explosion-proof security doors, thicken cavity with 8 layer TEFLON coating,

High-power exhaust system, program with suspend or start at any time. Ladder-style control temperature system,

the material is TFM for the vessel and aerospace composite material for the vessel cover,

The vessel cap with PFA and the pressure shrapnel use PEEK.

Optical fiber temperature control system

The instrument adopts the internationally advanced optical fiber temperature control system. It avoids producing the spark which other temperature control mode caused, effectively eliminates microwave interference temperature control system and other factors. It not only achieves precision control temperature but also it is the most safe microwave digestion temperature control mode at present.

The ARM chip with UCOS -II operation system

It is suitable for the experimental preparation equipment which runs stably and operates easily.

The advantages of MRS-45C type are:
1.The MRS-45C  Type is double screen, one 7″ LCD color touch-screen, another 5″ LCD Video monitor, can observed the dynamic experiment directly.

Other two types can’t.
2. Remote control system- MRS-45C only, based on Wi-Fi technology, peer to peer control. Other two types don’t have the function.
3. Digestion method: 50 preinstalled methods, programing 100 methods, more than other two types.
4.10 Teflon coating, more safety.

The microwave chemical reactor can control the microwave temperature, and adjust the timing function and power. It has functions such as over-temperature protection and abnormal sensor protection. The inner shell is made of stainless steel, which is durable, reliable and safe.

1. Safe interlock switch. Open the oven door under any circumstances to stop the microwave output. And equipped with protective gas inlet.
2. Open reaction system, according to the reaction conditions, a standard reaction vessel (volume 10-500ml) and devices for condensing reflux, dripping, liquid replenishment and water separation can be added arbitrarily.
3. The contact type tetrafluoroethylene temperature sensor can detect the internal temperature of the reaction system. The temperature measurement accuracy is 0.2, and the temperature control accuracy is less than ±1℃. The temperature control range is 0-250℃, and it has a temperature error correction function.
4. Temperature error correction function, if there is an error between the displayed temperature and the actual temperature, it can be automatically corrected.
5. The distribution of keys conforms to operating habits, with reasonable spacing and voice prompt function.
6. Display real-time curve function: Let you view the temperature change more intuitively.
