Closed Vessel Microwave Chemistry Workstation
SELON-8G Closed Vessel Microwave Digestion/Extraction System is a microwave chemical sample preparation equipment with excellent performance and reliable quality which is manufactured by improving the original SELON-8 closed vessel microwave chemistry workstation with newest materials and production technique by SELON Scientific Instrument Co., Ltd. Outer vessel made of super aerospace composite fiber material, which is only equipped for current international high-end microwave chemical apparatuses is applied in SELON-8G; it has light weight, durable performance and strong transverse impact-proof; it cannot have be cracked or broken under the action of explosion; its strength is higher than all other polymer engineering plastics and even steels. In this way, fusible, inflammable and explosive defects of polymeric plastic under high temperature and pressure are eliminated thoroughly and safety of operation is improved greatly. The SELON-8G high throughput microwave digestion/extraction system is applicable to microwave digestion, extraction, synthesis and many other application fields.
Technical advantage:
1) Outer vessel is made up of super aerospace composite fiber material with independent research and development. The outer vessel cannot be broken, torn and cracked under the action of explosion, and meanwhile it is provided with various features of corrosion resistance, high-temperature resistance, and impact resistance, pressure-withstanding. Thus, it far exceeds the outer vessel manufactured with PEEK and fundamentally resolves the potential safety hazard during the use by operators.
2) The combined application of quantified vertical blast pressure-relief technology and outer vessel made of composite fiber material do avoid the personal injury and damage to instruments caused by traverse bursting due to sudden reaction or violated sample-preparation during digestion. Thus, this product can be really compliant with safety design concept of vertical blast.
3) The instrument adopts piezoelectric crystal sensing and highprecision temperature sensing up to international advanced level capable of improving the accuracy for pressure and temperature measurement. The piezoelectric crystal sensing technology can allow the sample in master vessel to be completely isolated during pressure measurement to prevent several problems such as leakage from traditional gas-guide tube and enclosed interface of waterline pressure and cross contamination of samples.
4) The instrument maintains the non-pulse continuous microwave heating technology and ideally achieves the automatic closed-loop control of microwave power based on pressure and temperature feedback in order to realize the purpose of accurate control on reaction parameters and accurate display for congruent relationship between pressure and temperature and changing process during reaction. Meanwhile, trend curve of pressure, temperature and time can be switched into from time to time for the convenience of observation and analysis of operators.
5) Combined passive protection measures, pop-up buffer safe anti-explosion sliding chamber door and high-strength safe protective cover forms the vertical security and protection system to allow the operators to feel relieved.

Technical index:
1) Piezoelectric crystal pressure transducer conducts real-time control and displays pressure in digestion vessel and pressure rise curve, with scope of 0-10MPa (1500psi), and accuracy of ±0.01MPa
2) High-precision platinum resistance temperature sensor conducts real-time control and displays temperature in digestion vessel and temperature rise curve, with controlled temperature scope of 0-300°C and accuracy of ±1°C.
3) The structure of pop-up buffer safe anti-explosion sliding stove-door: when something abnormal occurs, the pop-up buffer structure can guarantee that operators are safe and stove-door structure is undamaged.
4)High throughout sample processing allows up to 8 or 10 samples to be simultaneously processed. In addition, 1-8/10 samples can be processed respectively.
5) High-pressure closed digestion vessel adopts high strength frame structure with safe and reliable anti-explosion mechanism. Auxiliary vessel-opening design with reduced pressure makes the operation easier and more convenient. The double-layer vessel structure: the maximum pressure can exceed 15Mpa (2250psi); the maximum temperature≥300°C and the volume is 100ml. The inner vessel adopts TFM material, and the outer vessel adopts super aerospace composite fiber material.
6) The forced cooling of all reaction vessels in chamber have the program prompt alarm for safety cooling. In addition, the cooling can be done outside the chamber. Since the composite fiber material has unique conductivity for heat, cooling speed is faster and the utilization ratio of chamber will be higher.
7) The design of uniform chamber (microwave resonance cavity) can guarantee that all samples are processed at the same time. In addition, the multiple anticorrosion painting can guarantee the chamber resists the corrosion from various acid gases and solvents.
8) The high-power exhaust system is equipped with chamber, thus every reaction can be done in the environment which is ventilated, safe and easy to observe reaction for a long period of time.
