Microwave Digestion System, MDS-100-R8

MDS-100-R8 is a sample pretreatment device that uses microwave energy to heat acids and samples in a closed container, rapidly and efficiently decomposing (digesting) solid or complex organic/inorganic samples into clear solutions under high temperature and high pressure conditions. Equipped with multiple active and passive safety protection functions, a specific mid-infrared non-contact temperature sensor that can penetrate TFM scans and monitors the true temperature of each sample solution in real time. The full tank pressure control technology ensures precise pressure relief for each reaction tank, ensuring the digestion of various samples in the most economical and efficient way to achieve the best results.

	Microwave focusing technology Accurate heating: Realize more precise and uniform heating effect, avoiding uneven heating phenomenon in microwave heating. High efficiency and energy saving: improve heating efficiency, reduce energy waste, and thus save energy. Safety and environmental protection: avoid the harm of microwave radiation to human body and environment, with better safety and environmental protection.
High-precision true temperature feedback Mid-infrared temperature sensor, real-time scanning and monitoring of the actual temperature of all sample solutions.
	Full vessel pressure control The safety pressure-limiting design ensures the digestion vessel is completely sealed and leak-proof during normal operation. In case of over-pressure, it automatically relieves pressure, guaranteeing operational safety.

Application Fields

Plastics and polymers	Cosmetics	Metals and alloys	Geological samples

Features

• Furnace door and door lock structure

High-strength safety explosion-proof door, side-opening door opening method and floating buffer design, can float and release part of the pressure when the pressure in the cavity is too high, taking into account both safety and ease of use.

• Corrosion-resistant exhaust system

High-flow exhaust system efficiently dissipates excess heat from the exterior walls of digestion vessels during the digestion process, prolonging operational lifespan and enabling rapid post-digestion cooling.

• Sample loading mode

Load or unload samples one by one without the need of moving the rotor.

• Temperature control mode

Utilize mid-infrared non-contact temperature sensor capable of penetrating TFM material to scan and monitor the actual temperature of all sample solutions in real time and display the temperature change curve.

• Pressure controlmode

The fully sealed design prevents pressure release during digestion, ensuring safety. This enhances sample digestion capability, particularly for difficult-to-digest samples. Precise pressure control for each reaction vessel guarantees operational safety.

• Active and passive safety protection

Features real-time full-sample temperature monitoring, over-temperature/over-current protection, abnormal noise detection, and a self-diagnostic fault alarm. Combined with high-temperature/pressure resistant vessel materials and a high-volume centrifugal exhaust fan.

• Smartcontrol

Built-in touch screen control, various working parameters and status shown on screen in real time.

• Method setting

100 digestion method parameters can be set, modified, and stored at any time, and each method can have up to 10 digestion stages.
