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. We 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°C
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 400-600mm 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 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, we acquires the pressure measuring technology by piezoelectric crystal, reliable and durable. Such technology may measure and control the pressure under 12MPa. 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 our product, more reliable than units with temperature monitoring only.
