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 digestion rotor in chamber, etc.

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 MDES 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.  Explosion-proof outer vessel made of composite Xtra Fiber, better than those similar products on the market.
The composite Xtra Fiber material is light, thin, and having better hardness (better than metal) and good rigidity. Moreover, its pressure resistance and corrosion resistance performances are much better than PEEK (Poly-Ether-Ether-Ketone) outer vessel. It applies painted PFA processes, improves the corrosion-proof capacity by packing the composite fibers totally. Moreover, the high tensile invincible composite material may withstand pressure of 10000psi and temperature of 500-600℃.

2.  Advanced and reliable pressure measuring technology by piezoelectric crystal.
At present, the air-pipe is generally applied to transmit, measure and control the pressure inside the vessel for most venders. The air-pipe has apparent demerit that is too long, usually 400-600 mm in length. Hence, the digestion turntable shall rotate back and forth in 360 degrees to avoid the air-pipe being twisted. Besides, the samples in master vessel may be polluted easily, and it may not withstand high pressure to prevent breaking the air pipe. Therefore, after years of research and development, It acquires the pressure measuring technology by piezoelectric crystal, reliable and durable. Such technology may measure and control the pressure under 12 MPa. The measuring and control cable is quite short, only 120-140 mm, therefore, there will be no twisting, sealing joint or leakage. Such technology allows easy operation and its greats merit is the absolute isolation of measuring and controlling component and sample, thus giving no chance to cross contamination. Integrating the technology of synchronous rotation of temperature-pressure device and digestion vessel with the rotary table in one direction and the patented technology of junction box, the turntable plate may rotate towards one directly constantly. The pressure control system is the standard configuration of product, more reliable than units with temperature monitoring only.

Piezoelectric crystal is installed on the bottom or top of the vessel frame like an electronic balance, and the parameter of pressure will be delivered via electrical signal.

3.  The temperature inside the digestion vessel can be controlled by the combination of precise measure of temperature inside master vessel and IR temperature scanning.
The precise measurement and control of temperature inside the master vessel (Pt or optical fiber) combines with the IR temperature scanning, and the computer may identify the master vessel automatically and give the real-time comparison of temperature with standard vessel, more precise and reliable than only IR temperature measuring.

4.  High throughput rotor with optional strong magnetic stirring function specially for extraction or synthesis.
Ultra high pressure and high temperature 18-vessel digestion vessel and carousel may work under 6MPa and 260℃, quite suitable for digestion of insoluble samples or closed microwave synthesis under extreme conditions. The strong magnetic stirring function is available for this configuration.

5.   200ml vessels for large volume sampling. LV-200 carousel with16-200ml vessels can be reacted simultaneously, and the sample size can reach 1-2 g. Magnetic stirring makes samples be digested faster and thoroughly. The patented design of innovative Safety Bolt can guarantee the safe as well as a completely digestion. The demand of large sampling digestion can be met.

6. Wireless remote visual monitoring system make reaction be clear at a glance.
Innovative remote wireless video monitoring system, makes the digestion process clearly visible. Mobile phones and tablets can realize the observation and monitoring of the reaction, making the operation safer and more convenient.

7.  100-vessel ultrahigh throughput closed microwave digestion vessel and carousel breakthrough products for the industry.
To adapt to the rapid development of advanced analytical instrument, the requirement for limit of detection, volume of sample, acid amount and blank interference are decreased, but the amount of samples to be detected are increased. Therefore, small volume, good pressure-bearing capacity and excellent batch processing performance, has become the trend for the development of microwave digestion technology. After releasing the first microwave digestion apparatus with 40 vessels at home, we cooperated with National Research Centre of Geoanalysis and developed MDES-100. Its unique UTH-Caro design is based on the previous designs and technologies of high throughput products. Such product is well received by the users in geological industry, food industry, sanitary inspection industry and environment industry. The 100-vesssel digestion carousel has 3 volume specifications, 15ml, 30ml and 50ml, and it may be customized according to the specific requirement of the user.
