MWD-800 Microwave Digestion System for High-Precision Metals Analysis

Overview of MWD-800 Microwave Digestion System

The MWD-800 Microwave Digestion System is designed for advanced laboratory sample preparation in elemental analysis workflows. It delivers controlled high-pressure, high-temperature digestion conditions that ensure complete decomposition of complex sample matrices before instrumental testing.

This microwave digestion system is widely used in environmental laboratories, food safety testing centers, pharmaceutical quality control departments, geological research institutes, and industrial analytical laboratories. It is particularly effective for microwave digestion for metals analysis, supporting accurate detection of trace and ultra-trace elements in challenging samples.

By combining high throughput capacity, precise monitoring technology, and strong safety architecture, the MWD-800 supports laboratories requiring reliable and repeatable digestion performance for ICP-OES, ICP-MS, and AAS analysis.

High Throughput Design for Laboratory Efficiency

The MWD-800 Microwave Digestion System is built for batch processing efficiency, accommodating up to 40 digestion vessels per run. This capacity significantly improves laboratory productivity and reduces sample preparation bottlenecks in high-demand testing environments.

Each digestion cycle is optimized for consistent energy distribution, ensuring uniform reaction conditions across all vessels. This allows laboratories to process multiple sample types simultaneously without compromising digestion quality or analytical accuracy.

The system is suitable for laboratories handling large workloads in environmental monitoring, industrial compliance testing, and research applications requiring continuous sample throughput.

Advanced Digestion Vessel Technology

A key feature of this microwave digestion system is its specially designed digestion vessel structure. The vessels integrate an auto vent and self-resealing mechanism, enabling automatic pressure release in case of sudden over-pressure events.

This intelligent structural design ensures:

• Prevention of vessel damage during high-pressure reactions

• Reduced risk of sample loss during digestion

• Stable batch operation without interruption

• Improved safety during aggressive acid digestion processes

The vessels are constructed using imported TFM material, providing excellent chemical resistance and durability under harsh digestion conditions. This makes them suitable for strong acid systems commonly used in metals analysis.

Real-Time Contactless Monitoring Technology

The MWD-800 Microwave Digestion System features a dual contactless monitoring architecture for precise process control.

Temperature Monitoring

Each vessel is equipped with an infrared non-contact temperature sensor, which directly measures the temperature of the sample solution rather than the vessel wall. This ensures highly accurate thermal readings during the entire digestion process.

Temperature control range: 50–400°C
Maximum working temperature: 250°C
Temperature accuracy: ±0.1°C

Pressure Monitoring

A contactless pressure detection system monitors each vessel independently, providing real-time pressure data during operation.

Pressure control range: 0–15 MPa
Maximum working pressure: 6 MPa
Pressure accuracy: ±0.01 MPa

This dual monitoring approach ensures stable digestion conditions while preventing cross-contamination between samples, which is critical for trace-level elemental analysis.

Intelligent Method Storage and Programming

The microwave digestion system supports advanced method management functions, allowing laboratories to create structured digestion protocols for different sample types.

The built-in control platform can store up to 255 digestion methods, each method supporting up to 10 programmable steps, including:

• Temperature settings

• Pressure limits

• Time control

• Microwave power adjustment

This flexibility enables laboratories to standardize procedures across multiple operators and maintain consistent analytical results over time.

Safety Protection Architecture

Safety is a core design principle of the MWD-800 Microwave Digestion System. Multiple protection layers ensure safe operation under high-pressure and high-temperature conditions.

Key safety features include:

• Double-locked security door structure

• Real-time temperature and pressure monitoring

• Automatic over-pressure and over-temperature regulation

• Abnormal acoustic detection system

• Corrosion-resistant airflow exhaust system

These integrated safety mechanisms provide stable operational protection for laboratory personnel and sensitive analytical environments.
