After successfully release WX-300 type instrument, which is the first marketing Microwave digestion with dual-control of temperature control and pressure control, Shanghai EU chemical Analytical Instrument Co., Ltd make innovation continuously, develop quickly, at the beginning of 2005, the completely new upgrading product－WX-4000 microwave quick digestion system is released.

WX-4000 microwave quick digestion system configuration with complete new designed frame microwave high pressure digestion Multi-Selected Vessel, the Multi-Selected Vesselbody consists of inner Multi-Selected Vessel, pressure-tight sleeve and frame, adopting innovative open-type frame design, after digestion, the Multi-Selected Vesselbody may be cooled down quickly with air or water, the cooling speed with forced air is average 15 min., the apparent rising of cooling speed completely overcome the shortcoming of home made old product－cooling speed slow, waiting time long, experiment period long etc., so, WX-4000 product raise the working efficiency greatly. The sleeve and frame adopt international latest pressure-tight material, implement the vertical oriented explosion protection function by frame-type design, the safety and service life are upgraded greatly. Furthermore, fitted with special tools for handling, the handling operation of the Multi-Selected Vesselbody is more facile.

Adopting complete new operation system and big screen liquid crystal display, programming and storing multiple digestion program, the programmable temperature rise and real time display the temperature, pressure in the Multi-Selected Vesselcan be realized. It meets requirements of America standard of EPA and ASTM to enable experiment operation more convenience and operator friendly.

Succeed WX-3000 type double-control of temperature control and pressure control property, fitted with high precise measuring & controlling system of pressure and temperature，real time measure and control the pressure and temperature in the digestion Multi-Selected Vesselwith high precise and perfect safety and protection measurers.

Shanghai EU chemical Analytical Instrument Co., Ltd. Collect the advanced technology at home and abroad and the specialized experience of developing microwave equipment for many years, take up with research and development for microwave chemical equipment with domestic leading technology and independence intellectual property, and serve greatness laboratory workers heart and soul.
