1. Product introduction:
NB-990A closed type intelligent microwave reaction/extraction workstation adopts advanced and sensitive optical fiber temperature measurement technology and full tank pressure measurement technology to realize real-time monitoring of the real temperature and pressure of all samples in the tank, greatly enhancing the safety of multi-tank microwave pre-processing equipment. It solves the problem that the uniformity and safety of the digestion cannot be reliably guaranteed when most single-point pressure measurement microwave digestion instruments are digesting multiple tanks at the same time. The industrial-grade stainless steel furnace chamber has strong resistance to explosion, more uniform microwave radiation, built-in PFA protective film, and is anti-corrosion, and easy to clean. It is widely used in microwave pretreatment of samples in food, cosmetics, medicine, feed, environment, soil, mining,
textile, biology, light industry, rock, metallurgy and steel, organic and polymer, ceramic and inorganic
materials
.Description of technical parameters
NB closed type intelligent microwave digestion/extraction workstation
Technical parameters
Power and frequency: non-pulse variable frequency microwave power adjustment function; maximum
microwave power: 1000W; microwave frequency: 2450MHz;
1.Microwave radiation furnace chamber: industrial-grade 316L stainless steel furnace chamber
volume is 35L; the inner surface of the furnace chamber is 6-layer PFA corrosion-resistant coating, which
has a long service life and is easy to clean;
2.Sample volume and quantity: The volume of each sample digestion tank is 100mL, which can digest
1-6 samples at the same time;
3.Rotary table rotation mode: One-way continuous rapid rotation (2 seconds/circle), and each tank
position can receive microwave energy more evenly.
Temperature monitoring method: using optical fiber temperature sensor to monitor the real
temperature of the sample solution in real time, and display the temperature change curve;
Full tank pressure monitoring: a patented non-contact pressure sensor that 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: 0~300ºC (±0.1ºC);
pressure measurement range: 0~10MPa (± 0.01MPa);
High-pressure digestion tank: the outer tank is made of imported high-strength fiber composite PEEK,
and the inner tank is made of imported modified polytetrafluoroethylene (TFM). Maximum pressure
resistance ≥15MPa, maximum temperature resistance ≥300ºC; working temperature: room temperature
-250ºC, working pressure range: 0-6Mpa.
4.Safety design of furnace door: The furnace door has a double microwave shielding mechanism, and
a door locking self-checking device to protect the operator from microwave radiation. The furnace door
adopts a buffer hinge design to maximize the life and safety of the furnace chamber.
5.Multiple safety protection measures: The instrument is equipped with up to 10 active and passive
safety protection functions, including industrial-grade high-strength furnace chamber and buffer
explosion-proof safety door design, furnace door linkage switch, real-time monitoring and protection of full
sample pressure, and over-pressure alarm restriction, abnormal sound detection, fault self-checking
alarm, and two 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.
Working mode: 1) 256 kinds of digestion methods can be programmed, modified and stored at will; 2)
each method can be set up to 10 digestion stages; 3) built-in automatic cooling mode, and the termination
cooling condition is adjustable;
Fully intelligent control: full touch screen operation, intuitive and simple; 7" super large screen real-time
display of various working parameters and status (such as temperature and pressure change curve, etc.).
Power supply: 220V AC, 50-60Hz;
power: 1500W
