The MWD microwave digester has been adhering to the principle and concept of "safe experiement", "efficient and convenient operation" and "durable use" from R&D to production. It can be widely used in routine laboratories and also applied under extreme conditions. MWD adopts advanced dual magnetron non-pulse frequency microwave heating technology, realizing the high power microwave heating & homogeneous heating; At the same time, MWD's highly intelligent man-machine dialogue operation system and wireless control module make the experiment process become efficient, convenient and humanized, and bring safe and comfortable experience to users.


Main features:


Optical fiber temperature control system is safe, meanwhile it can realize accurate temperature control. Optical fiber avoids the drawbacks ofantenna effect of conventional metal resistance temperature sensor, and solves multi-vessel digestion temperature deviation and unevenheating, adopts advanced multicore integrated optical fiber sensor, with an optical fiber diameter of 2 mm, its uses Teflon protectivecoating, and has small bending curvature, good fold-resistant and flexibility. The service life is 5 times longer than the single core optical fiber. MDW adopts advanced high-precision semiconductor pressure sensor, the whole conduction path conducts the anticorrosion treatment,realizing precise pressure control, with pressure precision of ±0.01MPa. MWD series has 2 magnetron, and its inverter microwave heating makes real-timeadjustment of microwave output power according to the temperature and pressurefeedback, thus the microwave f ield is more uniform and the control more precise.Inverter microwave heating can avoid the disadvantages of pause heating andfrequent startup, effectively protect the magnetron, and reduce energy loss. Doublemagnetron heating and professional microwave focusing design can make the magnetic field distribution inside the furnace chamber more even, ensuring theconsistency of the experimental sample digestion. MWD adopts aerospace composite fiber materials Xtra Fiber to make the outer vesselwhich is invincible that can withstand 80 MPa pressure, completely eliminating thepossibility of radial blasting. Its corrosion resistance, high temperature resistance andshock pressure and many performance indexes are excellent, fundamentally solvingthe dangers in the process of using.


MWD adopts ARM chip equipped with UCOS-II operating system, with stable and reliableoperation. It uses 7 inches of LCD touch screen, with touch control for operation, smooth andsimple. The screen gives the real-time display temperature- pressure curve. It has a built-inexpert method library, which can be edited and store user methods. Built-in COT real-time T/Pabnormity monitoring system can give automatic alarm when any reaction vessel hasabnormal temperature and pressure, and cut off the microwave so as to protect theinstrument. P version (MWD-P) has the Wi-Fi wireless control module, not only realizingpoint to point control between the computer and the microwave digestion instrument, butalso using a tablet PC to realize control and real time observation within the local area network (LAN). It brings better experience for "comfort experiment and safe experiment". P version also adopts double screen design and is equipped with 5 inches of LCD color displayfor real-time monitoring of digestion vessel operation inside the furnace chamber throughinternal camera.


With MWD 12-vessel of high throughput digestion capacity, it meets the pretreatment requirements of bulk samples. It adopts high-strength composite materials for enhancing strength, and reaches 1.7 tons of tensile test requirements, and its high pressure resistant frame is of thickening customization and canbear the high pressure during digestion. PEEK elastic tablet can resist high temperature, has larger rigidityand stable dimension, reach 19 MPa for bending strength and compression strength at 260°C, and canprotect PFA vessel cover from being damaged during the digestion. MWD digestion adopts thedesign of automatic pressure release, which puts an end to the occurrence of dangerous high pressureexplosion, and cancels safety membrane and other consumables, simple use and low cost.


MWD’s 316 stainless steel industrial furnace chamber adopts modular design concept, providing great convenience for the upgrading andmaintenance of equipment. The furnace door is made of multiple protective layers, and internal furnace chamber adopts multi-layer Tefloncoating, greatly improving the service life and safety guarantee of the instrument. The optimized groove structure design can eliminate themicrowave leakage. It will automatically cut off microwave when the door is opened naturally or forcibly, protecting the user's safety. Efficientexhaust system design can realize the fast and safe air cooling (drop from 200°C to 80°C within 15 minutes), improving operation efficiency.
