Closed Type Intelligent Microwave Digestion/Extraction Workstation

Technical parameters
Power and frequency: high-frequency high-power resonance programmable high-voltage microwave power supply. Industrial-grade dual magnetron microwave output power range, 0~2400W (arbitrary adjustment); microwave frequency, 2450 MHz;
★Microwave radiation furnace chamber: the volume of the barrel-shaped 316L stainless steel furnace chamber is 75L; the inner surface of the furnace chamber is multi-layer PFA corrosion-resistant coating, which has a long service life and is easy to clean;
Sample volume and quantity: 12-position, 16-position, 26-position, 42-position rotary table can be adapted; the volume of each sample digestion tank is 100mL (12-position and 16-position) or 75mL (26-position and 42-position).
★Automatic identification of furnace chamber: automatic identification of 12-position, 16-position or 42-position rotary table, without any setting, replace and use, convenient for expansion.
★Sample loading method: Top rotating and translating furnace door, and the sample is loaded/taken out from the top.
★Temperature monitoring method: a specific mid-infrared non-contact temperature sensor that can penetrate the tank scans and monitors the real temperature of all sample solutions in real time, and displays the temperature change curve.
★Pressure monitoring method: a non-contact pressure sensor designed based on the principles of highly elastic dish-shaped metal shrapnel combination and optical distance measuring system, which scans and monitors the real pressure of all samples inside the digestion tank in real time, and displays the pressure change curve.
Temperature-pressure measurement system: temperature measurement range: room temperature~400°C (±0.1°C)；pressure measurement range: 0~10MPa (± 0.01MPa).
Digestion tank: high-pressure position frame-type ultra-high pressure digestion tank, the outer tank is made of  imported high-strength composite fiber PEEK; the high-throughput version of the outer tank is aerospace-compliant fiber material; the inner tank is made of imported modified polytetrafluoroethylene (TFM) . Working temperature: 0-250℃, maximum temperature resistance: ≥300℃; maximum pressure resistance: ≥15MPa; working pressure range: 0-6.Mpa (12/16 position), 0-4.Mpa (42 position);
★Working mode: 1) 256 digestion methods can be programmed, modified and stored at will; 2) each method can be set up to 10 digestion stages; 3) built-in intelligent heating rate control mode and constant temperature control mode; 4) built-in automatic cooling mode , and the termination cooling condition is adjustable.
★Data storage\view function: the method and process data of each experiment can be stored; the historical data can be viewed on the display of the instrument.
★Multiple safety control: The instrument is equipped with up to 10 active and passive safety protection functions, including industrial-grade high-strength barrel-shaped furnace chamber and overhead explosion-proof furnace door design, real-time monitoring and protection of real temperature/pressure of all samples, over-pressure alarm limit, elastic pressure stability protection device, overheat and over-current protection, abnormal sound detection, fault self-check alarm, high temperature and high pressure tank material, non-destructive pressure relief groove and three powerful centrifugal exhaust fans with large air volume of 5.8m3/min to prevent the instrument and the operator from being affected by harmful gases.
Fully intelligent control: full touch screen operation, intuitive and simple; super large screen real-time display of various working parameters and status (such as temperature and pressure change curve, etc.); equipped with standard RS232 interface, which can be connected to a computer.
