Microwave Digestion System，BNMD-106

The outer vessel 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 tempera- ture 500-600°C, fundamentally eliminating safety risks to operator in use.
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.
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.

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
