MWD-610 Series Microwave Digestion System for Safe and Precise Sample Preparation

Product Overview

The MWD-610 Series Microwave Digestion System from METASH is designed for efficient and controlled digestion of complex samples before elemental analysis. It combines microwave heating with contactless temperature and pressure monitoring to provide accurate control of sample conditions throughout the digestion process. The solution is suitable for laboratories requiring reliable sample preparation for applications such as ICP-MS, ICP-OES, and atomic absorption analysis.

With support for 6, 8, 10, or 12-position sample rotors, the microwave digestion system provides flexible batch processing for different laboratory workloads. Each vessel can be monitored and controlled independently, helping improve digestion consistency while reducing variations between samples.

Contactless Temperature and Pressure Monitoring

The MWD-610 uses imported contactless IR and pressure sensors to monitor the actual temperature and pressure of the sample solution, rather than relying on vessel-wall measurements. Temperature can be controlled from 50 to 400°C, with a maximum working temperature of 250°C, while pressure control ranges from 0 to 15 MPa with a maximum working pressure of 6 MPa.

Real-time temperature and pressure curves can be displayed on the 7-inch color touchscreen, allowing operators to observe digestion conditions throughout the process. This design supports more precise method development and repeatable sample preparation.

Safe Closed-Vessel Digestion

Safety is an important consideration when processing samples under elevated temperature and pressure. The MWD-610 features an auto-vent and self-resealing vessel design to help manage pressure conditions while reducing potential element loss during digestion. A double-locking protection structure provides an additional layer of operational safety.

The digestion cavity is manufactured from 316L stainless steel and protected with multiple corrosion-resistant and heat-resistant coatings. Professional electromagnetic protection and microwave leakage control further support safe laboratory operation, with microwave leakage maintained below 5 mW/cm².

Flexible Methods and Batch Processing

The microwave digestion system can accommodate different sample quantities through interchangeable 6/8/10/12-position rotors. A 360° continuous rotating design promotes more uniform microwave exposure during digestion, helping improve processing consistency across vessels.

The intelligent touchscreen interface provides straightforward operation and method management. Multiple international application methods are pre-installed, while users can edit, modify, save, and delete digestion methods according to specific sample requirements. Up to 255 method programs can be edited and stored for convenient routine analysis.

Lower Maintenance and Efficient Cooling

The MWD-610 is designed without consumable components such as bursting disks and sealing cups, helping reduce routine replacement requirements and maintenance costs. A high-power turbulent air cooling design accelerates the cooling process after digestion, supporting faster preparation for subsequent laboratory procedures.

Microwave power is adjustable from 0 to 1000W, allowing operators to select appropriate heating conditions for different sample matrices. The corrosion-resistant air exhaust design also helps maintain a suitable working environment during operation.
