MWD-800 Microwave Digestion System for High-Throughput Elemental Analysis

Product Overview

The MWD-800 Microwave Digestion System is a high-performance sample preparation solution designed for laboratories requiring efficient, accurate, and safe digestion processes. With a capacity of up to 40 digestion vessels, this advanced microwave digestion system is suitable for batch experiments and high-throughput elemental analysis applications.

By combining powerful microwave energy control, precise temperature and pressure monitoring, and intelligent safety protection technologies, the MWD-800 helps laboratories achieve consistent sample digestion results for ICP-OES, ICP-MS, AAS, and other analytical instruments. It is widely used in environmental testing, food analysis, pharmaceutical research, geological inspection, and industrial quality control.

High-Capacity Design for Efficient Batch Digestion

The MWD-800 microwave digestion system supports up to 40 vessels, making it an ideal choice for laboratories handling large numbers of samples. The high-capacity configuration improves workflow efficiency while maintaining stable digestion performance across all vessels.

The optimized rotor design ensures uniform microwave energy distribution, allowing multiple samples to be processed simultaneously. This reduces preparation time and increases laboratory productivity without compromising digestion accuracy.

Advanced Digestion Vessel Design for Enhanced Safety

Safety and sample protection are essential during high-pressure acid digestion. The MWD-800 is equipped with specially designed digestion vessels featuring auto vent and self-resealing technology.

When unexpected over-pressure conditions occur, the vessel can automatically release excess pressure and quickly reseal itself. This innovative structure helps prevent vessel damage, reduces sample loss, and minimizes the risk of element loss during the digestion process.

The durable vessel design also improves long-term reliability, making the microwave digestion system suitable for demanding laboratory environments that require continuous operation.

Contactless Temperature and Pressure Monitoring

Accurate monitoring of digestion conditions directly influences analytical results. The MWD-800 uses imported contactless infrared temperature sensors and pressure sensors to provide real-time monitoring of each individual vessel.

Unlike traditional measurement methods that detect vessel wall temperature, the contactless IR sensor measures the actual temperature of the sample solution. This improves control accuracy and ensures that digestion conditions are monitored more precisely.

The pressure monitoring function provides real-time pressure data from each vessel, allowing operators to clearly understand digestion progress throughout the entire process. This technology reduces the risk of sample cross-contamination and supports more reliable elemental analysis results.

Flexible Method Programming and Intelligent Operation

Different samples require different digestion conditions. The MWD-800 microwave digestion system allows users to create, edit, and store up to 255 digestion method programs, providing excellent flexibility for various applications.

Each method can include up to 10 programmable steps with adjustable parameters, including:

• Temperature settings

• Pressure control

• Digestion time

• Microwave power adjustment

The built-in 7-inch color touch screen provides a user-friendly interface for simple operation and real-time monitoring. Laboratory personnel can easily manage digestion procedures, modify parameters, and review operating conditions during the entire process.

Comprehensive Safety Protection System

The MWD-800 integrates multiple safety technologies to ensure stable and secure operation during high-pressure microwave digestion.

The system features a double-lock safety door, automatic over-pressure adjustment, over-temperature protection, and abnormal sound monitoring functions. These protection mechanisms work together to create a safer operating environment for laboratory users.

The microwave cavity is manufactured with a 316L stainless steel structure and coated with corrosion-resistant and heat-resistant materials. This design provides excellent chemical resistance and extends equipment service life when handling aggressive digestion reagents.

Efficient Cooling and Reliable Performance

High-efficiency cooling is important for improving laboratory workflow. The MWD-800 adopts a powerful corrosion-resistant air exhaust and cooling design to accelerate temperature reduction after digestion.

The adjustable microwave power range of 0–3000W provides flexible energy control for different sample types. Combined with accurate temperature and pressure management, the system delivers stable digestion performance for complex samples.
