Super Microwave Digestion System CNWB-8H - Fully Automatic Pressure Relief, Safe and Reliable

Super Microwave Digestion System CNWB-8H - Fully Automatic Pressure Relief, Safe and ReliableAt the pinnacle of modern sample pretreatment technology, this is specifically designed for the rapid and complete dissolution of complex matrix samples. Compared to traditional hotplate or conventional microwave digestion techniques, "Super Microwave" typically signifies higher energy efficiency and more precise temperature and pressure control. The CNWB-8H utilizes advanced microwave generation and coupling technology to directly and evenly apply energy to the mixture of samples and acid within the digestion vessel, thereby thoroughly decomposing organic or inorganic samples into clear, uniform solutions within an extremely short time frame—usually just ten to several dozen minutes. This high-efficiency capability significantly boosts the sample throughput of laboratories, particularly suitable for large-scale and difficult sample pretreatment tasks in fields such as environmental, food, geological, and pharmaceutical sectors.

The core safety assurance and automation essence are embodied in the "Full-Automatic Pressure Relief" function. Traditional decompression processes require manual monitoring of pressure and manual relief, or with assistance from complex mechanical devices, posing operational risks and uncertainties. The CNWB-8H integrates an intelligent closed-loop pressure management system. The instrument monitors the pressure inside each decompression vessel in real-time through high-precision sensors during operation. The microcomputer control system then executes the pressure relief operation automatically and smoothly, based on pre-set safety thresholds and program logic, either after decompression is complete or when the pressure is nearing critical levels. This process requires no human intervention, eliminating the risks of acid mist exposure or burns that could arise from manual pressure relief, and ensures that the timing and speed of each pressure relief are perfectly consistent, fundamentally guaranteeing the safety of operators and the integrity of the samples.

Therefore, the Super Microwave Digestion System CNWB-8H fulfills its core promise of "safety and reliability" through its fully automatic pressure release mechanism. This reliability is evident throughout the entire workflow: from the efficiency and uniformity of the digestion process, to the automation and precision of the pressure release stage, and finally to the stability and high recovery rate of the final sample results. It establishes a standardized, error-free sample digestion solution for the laboratory, significantly reducing the risk of safety incidents due to improper operation and batch variations. For modern analytical laboratories that strive for high-throughput, high safety, and data accuracy, the CNWB-8H is more than just a tool to enhance efficiency—it is a crucial equipment for ensuring a smooth, reliable experimental process and personnel safety.

Super Microwave Digestion System CNWB-8H - Fully Automatic Pressure Relief, Safe and ReliableKey Features:

1. Achieve high-temperature and high-pressure efficient digestion of samples through microwave heating

2. Single Reaction Vessel Design: The microwave is directly emitted from the bottom to the vessel, ensuring that all samples placed within this reaction vessel are digested under strictly the same temperature and pressure conditions.

3. Offer at least 4 different capacity sample tubes for selection. Choose the tube specifications according to your needs.

4. Fully Automatic Enclosed Compartment: The digestion compartment's seal cover and gripper close and lock automatically, eliminating the need for manual operation and external tools.

5. Full automatic pre-pressure, pre-filling the cavity with inert gas, ensuring strict high-pressure digestion of the sample, over-pressure protection, and automatic pressure release; simultaneously, pressure balance between the tube and its surroundings is achieved, eliminating the risk of bursting.

6. Pressurized gas enters the cavity directly through the lid, avoiding intake on the exterior of the cavity, then being conducted to the lid's intake. Long-term sealing between the tank and lid can lead to leakage in the sealing rings, resulting in reduced pressure in the pressurization system. Prolonged exposure can easily cause leakage accidents, unexpected tightness issues due to deformation or leakage, and pressure not being adequately maintained.

7. Dual-phase steel cavity design, where microwaves are confined within a metallic cavity, ensuring a high-pressure safety of up to 20 MPa and preventing leakage.

8. Equipped with an efficient cooling method for rapid dissolving liquid cooling

9. Full Automatic Pressure Relief: Once the cavity is cooled to the set target temperature, it will automatically relieve pressure. The internal piping is coated with Teflon, preventing oxidation and acid corrosion.

10. It should be equipped with a high-precision temperature sensor for real-time control and display of the temperature inside the reaction vessel and its heating curve.

11. The hydraulic clamping section utilizes dual cylinders for operation, avoiding the unsafe factor of two points on a single cylinder, with the cylinders cooled by an external cooling water circulation system.

12. The platinum resistance temperature sensor extends from the bottom of the chamber into the interior of the housing, the workbench surface, featuring Teflon-lined intervals for corrosion resistance. It controls and displays in real-time the temperature and heating curve inside the reaction vessel.

13. The control system supports both wireless and wired connections, with simple and direct operation. The minimum storage space is no less than 128G, and no data export is required throughout the device's lifecycle. The operation terminal can play operation videos, view manuals, SOPs, and other files.

14. One-Touch Operation: The one-touch operation completes the sample dissolution process, including automatic lid closure, pressure increase, dissolution, cooling, pressure relief, and lid opening, with no manual intervention required throughout. Operators can stay away from high-temperature/high-pressure equipment.

15. Equipped with a deep cleaning module, it can automatically add water for cleaning and maintenance of the high-pressure pipeline system, reducing acid corrosion. The pipeline is located above the lid.
