I. Function parameters
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.

2. Product features (description of technological advancement):
Ø The microwave digestion workstation with technologically advanced optical fiber temperature sensor and full tank pressure scanning monitoring has a high safety factor;
Ø Industrial-grade microwave furnace chamber has strong anti-explosive power and more uniform microwave radiation. The furnace chamber is covered with multiple PFA anti-corrosion coatings.
1)Microwave system
1.1 High-efficiency exhaust air cooling: equipped with three powerful centrifugal exhaust fans with large air volume of 5.8 m3/min.
1.2 Using optical fiber temperature sensor with high sensitivity, which is not interfered by microwave.
Ø A non-contact full tank pressure monitoring system, which can monitor the reaction pressure status of each sample in real time during the digestion process
Ø (Non-contact full tank temperature and pressure control. Advanced mainstream technology, safety guarantee)
2)Safety class
As we all know, in the microwave pressure digestion process, the so-called "danger" is usually caused by the reaction "out of control" and the pressure beyond the tolerance range. The pressure sensor control system of NB-990A microwave digestion workstation monitors the pressure of each digestion tank in real time to solve potential safety hazards.
3)Sensor
3.1 Optical fiber temperature sensor, when the microwave reaches a certain temperature, it is not interfered by microwave, and the sensitivity is relatively high.
3.2 Pressure sensor, inside the top cover of the digestion tank, specially made material to react pressure, as an important part of pressure sensing, during digestion, continuously scans and monitors the pressure of each digestion tank in real time through rotation.
4)Software system
Ø Easy to operate, intuitive and concise, large screen display of various working parameters
Ø Equipped with RS232 interface, which can be connected with a computer
Ø More than 250 kinds of digestion methods can be freely programmed, modified and stored
5)Pressure digestion tank
Ø The number of samples that can be digested at the same time is 6-8, and the volume of the digestion tank is 100mL;
Ø The outer tank is made of imported hydrophobic high-strength pressure resistant PEEK®, and the inner tank is made of imported modified polytetrafluoroethylene (TFM). Maximum pressure resistance≥15MPa, and maximum temperature resistance≥300℃;
