WX 6000
The WX-6000 Microwave Digestion System is an innovative primary microwave instrument, which can simultaneous process 6 sets of 100mL vessel. It has the simple and practical operating function and satisfies variety types of sample digestion requirements.
The WX-6000 Microwave Digestion System is widely applied to the area of food, pharmaceutical and environment, which is an ideal choice for small-batch of sample pretreatment.





The WX-6000 Microwave Digestion System is a basic model which possesses dual temperature and pressure control directly via specific sensors assembly, high performance vessels and enhanced protection door, meeting the application in the high pressure range. The WX-6000 System, specially ideal instrument for a beginner, is easy to master this new method of sample preparation, changing the traditional method.

• Classic microwave source design: Adopt Panasonic inverter technology and realize non-pulse continuous microwave output, which can satisfy small-batch continuous tunable microwave output.

• Dual temperature and pressure measurement and control system: Temperature sensor directly monitors and controls temperature change inside the reaction vessel in real time. High precision high temperature melt pressure sensor directly measures the pressure of the reaction vessel in real time and cooperates with temperature sensor to control the pressure.
