Microwave Digestion


Set a new brenchmark for practical compact microwave digester

  • All-steel industrial grade chamber with corrosion resistance and ultra-long life;
  • Ultrastrength aerospace composite fiber digestion outer vessel;
  • Exclusive patented multifunctional safety bolt design, instead of safety membrane and other consumables;
  • Precise pressure control by piezoelectric crystal without cross-contamination problem

MDES-6 microwave digestion/extraction/synthesis system (nickname: SMART), a subversion of tradition, is a market-oriented practical compact microwave digester made by Bioevopeak 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 SMART exclusively 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℃, fundamentally eliminating safety risks to operator in use.

Closed Microwave DigestionExtraction System1

Quantified vertical blast/safety bolt design, ensures samples be closed completely and trigger 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.

Closed Microwave DigestionExtraction System2

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 technique, ensure 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 %).

The patented design that the whole set of digestion vessels in chamber always continuous rotates in one direction, breaks conventions of <360° back and forth rotation of the digestion unit, avoiding uneven heating on vessels by microwave and reducing impact on turntable motor, extending service life.

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.
