Multi-channel microwave digestion system

The multi-channel microwave digestion system is a high-throughput, intelligent sample preparation device designed specifically for modern laboratories. The instrument utilizes high-performance industrial-grade magnetrons and intelligent temperature control technology, combined with a comprehensive multi-layered safety protection system, to ensure a safe and controllable experimental process. The device offers high-throughput sample processing capabilities. Combined with 360° unidirectional continuous rotation technology, it ensures uniformity and reproducibility in intra-batch sample processing. The control system utilizes contactless infrared precision temperature control, allowing for intuitive monitoring of the entire temperature curve via a large touchscreen, making operation smart and convenient.

The entire unit features a corrosion-resistant chamber and high-quality PEEK/PTFE digestion vessel components, ensuring a robust and durable structure. With its reliable core performance, comprehensive safety safeguards, efficient batch processing capabilities, and user-friendly intelligent operation, this instrument is the ideal choice for efficient and safe sample digestion in industries such as food, environmental, geological, and metallurgical.

The multi-channel microwave digestion system operates on the principle of combining microwave body heating with high-pressure chemical reactions. Microwaves emitted by the core magnetron are absorbed by polar molecules (such as water and acids) within the digestion vessels, causing high-speed molecular oscillation and friction. This enables rapid and uniform heating from within the sample, significantly reducing sample preparation time.

To ensure precise and controllable processes, the instrument employs non-contact infrared temperature sensing technology to continuously monitor temperature changes in each reaction vessel throughout the process. The unique 360° unidirectional continuous rotation design ensures uniform heating of all samples and consistent results. The system incorporates multiple built-in safety mechanisms; should any temperature or pressure abnormalities be detected, it immediately stops microwave emission and activates pressure relief protection, achieving a balance between high efficiency and safety.

• Stable and Reliable Core Performance with Durable Design
  ① High-Performance Magnetron System: Utilizes industrial-grade high-performance magnetrons with intelligent power regulation to achieve 0–1800 W non-pulsed continuous variable-frequency output. The system features a streamlined structure, stable and reliable operation, high energy conversion efficiency, and lower maintenance costs.
  ② Premium digestion vessel assembly: The inner vessel utilizes highly corrosion-resistant polytetrafluoroethylene (PTFE), while the outer jacket employs ultra-high-strength PEEK aerospace-grade engineering plastic. This configuration delivers a safe working pressure of up to 1500 psi (approximately 10 MPa) with exceptional durability.
  ③ Robust, corrosion-resistant cavity: Premium stainless steel microwave cavity with multi-layer Teflon anti-corrosion coating. Resists acid vapor corrosion, facilitates easy cleaning, and ensures long-term equipment durability.

• Multi-directional Active Intelligent Safety Protection System
  ① Dual Pressure Relief Safety Assurance: Each digestion vessel is equipped with an independent pressure relief device, while the main unit features automatic overpressure discharge functionality. This creates dual protection for both the vessel and the system, ensuring high safety redundancy.
  ② Self-Locking Buffered Explosion-Proof Door: Utilizes a high-strength self-locking buffered door that effectively absorbs impact during abnormal pressure events. Combined with electromagnetic interlocking, it ensures personnel and equipment safety.
  ③ Real-Time Monitoring and Automatic Shutdown: The temperature control system continuously monitors conditions. If parameters exceed limits, it automatically cuts off microwave power, enabling proactive safety intervention.

• High-Throughput, High-Consistency Efficient Processing Platform
  ① Maximum 16-sample high-throughput design: Processes up to 16 samples per batch, significantly boosting laboratory efficiency for large-volume sample processing.
  ② 360° unidirectional continuous rotation: The turret rotates continuously in one direction (non-reciprocating), ensuring uniform microwave exposure at each sample position. This fundamentally guarantees repeatability and parallelism within batches.
  ③ Efficient rapid cooling: An integrated high-power corrosion-resistant exhaust system enables rapid air cooling post-digestion, accelerating temperature reduction and shortening experimental cycles.

• Precision Intelligent Control and Operating System
  ① Smart Non-Contact Temperature Control: Utilizes high-precision non-contact infrared temperature measurement to directly monitor actual vessel temperatures, ensuring precise control (±0.5°C). This method is contamination-free, consumable-free, and delivers authentic, reliable data.
  ② Flexible Method Library: Supports user-defined digestion methods, easily accommodating standardized or customized pretreatment workflows for diverse samples.
  ③ Intuitive Human-Machine Interface: Large-size color touchscreen with graphical interface displays real-time tank temperature and pressure curves synchronously. Operation is intuitive, and processes are clearly visible at a glance.
