With the most advance technology and material of Shanghai Sineo Microwave Chemistry Technology Co., LTD., MASTER serial ultrahigh throughput microwave digestion/extraction workstation was launched in 2012. MASTER cavity is versatile for 16-vessel independent frame-type high pressure digestion rotor, 18-vessel carousel integrated ultrahigh pressure digestion rotor, 40/100-vessel ultrahigh throughput carousel rotor and 16-200ml-vessel carousel large capacity rotor etc., meets different experiment application requirements. Other core technologies including airplane Xtra Fiber digestion outer vessel, quantitative Safety Bolt patented design, UTH-Caro design of high throughput carousel, unique piezoelectric crystal pressure measuring technology and Uni-Turn technology of one direction continuous rotation of
With the popularity of analytical instruments, e,g, Mass Spectrometer, there are increasing demands of rapid and efficient microwave sample preparation instrument with high productivity. However, the present high throughput microwave digestion products on the market that mostly adopt the spring structure are those which may bear low pressure, be easy to be leaked, and may not be heated evenly and operated easily. The MASTER closed microwave digestion system is developed by aiming at coping all the above mentioned problems, and the followings may show its unique characteristics of the innovative technologies:
1. High-strength alloy carousel: higher pressure and better digestion performance.
The high throughput vessel, since being connected by the high tensile alloy draw bar, may withstand great pressure (≥10000Kg). Each digestion vessel may receive great supports from the vessel frame on its top and bottom and it may not be deformed or leaked under the pressure of ≤4MPa and temperature of ≤250℃. (However, those similar products made by other venders generally may bear the temperature of 210℃ maximally.)
2. UTH-Caro design makes the carousel stir the microwave, guarantee samples digested evenly
3. Safety Bolt: safer, more accuracy in result and higher recycling rate.
Quantified Safety Bolt design, ensures samples be closed completely and triggers a quantified pressure relief while over pressure; Safety Bolt unit, instead of safety membrane and other consumables, ensure the digestion vessel be sealed completely under normal working conditions, which avoids the loss of volatile elements and incomplete digestion. And only when the pressure is too high and may constitute a danger, 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 requires no replacement. In addition, it is easy for venting to open the cover after completion of digestion. (However, those similar products on the market may bear low pressure and temperature, and since the cover is not made of metal, it may not recover after deformation; consequently, it may be not flexible anymore and be useless as it loses its sealing function after several times of recovering. This is why the samples inside the digestion vessel are reduced or dried and it has low recovery rate.)
4. Uni-Turn technology, increased homogeneity and reliability.
The whole set of digestion vessels was designed to rotate continuously in one direction, it breaks conventions of<360° back and forth rotation, avoiding uneven heating on vessels and reducing impact on turntable motor to extend service life. The temperature and pressure cables are short, that they are free from twisting in running and can be disassembled easily.
