The outer vessel of MDES-15 exclusively made by ultra strength 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),fundamentally eliminating safety risks to operator in use.

Microwave Digestion

Quantified safety bolt design, ensures samples be closed completely and triggers a quantified pressure relief while over pressure; Safety Bolt unit, instead of safety membrane and other consumables,ensure the digestion vessel be sealed completely under normal working conditions, which avoids the loss of volatile elements and incomplete digestion. And only when the pressure is too high 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 requires no replacement. In addition, it is easy for venting to open the cover after completion of digestion.

Microwave Digestion

The industrial-leading pressure measuring technology by piezoelectric crystal and high-precision Pt sensor temperature measurement, through closed-loop control of microwave power by inverted technique, ensure the accuracy of pressure and temperature monitoring and control. The application of patented piezoelectric crystal brings 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 whole set of digestion vessels was designed to rotate continuously in one direction, it breaks conventions of<360° back and forth rotation, avoiding uneven heating on vessels and reducing impact on turntable motor to extend service life. The temperature and pressure cables are short, that they are free from twisting in running and can be disassembled easily.
The new industrial design is smart and colorful, that in line with the needs of modern laboratory construction needs.It re-layout its internal structure more scientifically, with the 65L industrial 316L stainless steal reactor chamber and dual magnetron structure, ensures uniform heating of the microwave and high microwave power emitting.

Microwave Digestion

Innovative remote wireless video monitoring system, together with the high-intensity transparent quartz vessel, makes the digestion process clearly visible. Mobile phones and tablets can realize the observation and monitoring of the reaction, making the operation safer and more convenient.

Sturdy and durable industrial-grade chamber design strengthen its impact resistance, and multi-layer chemical resistant coating greatly improves the service life and safety of the system; the pop up cushioning explosion-proof sliding chamber door (Auto-Pop structure) builds a passive safety protection system, and it can disable the microwave power automatically once explosion happens; efficient exhaust system design achieves fast and safe forced-air cooling (20 min cooling time from 200℃to 60℃), improving operational efficiency.
