A microwave digester is a laboratory device used to rapidly dissolve or decompose solid sample matrices into clear aqueous solutions using microwave energy and concentrated acids.

Kindly consult the person in charge (PIC) before proceeding with any booking.

Core Uses and Applications

1. Trace Metal Analysis: Preparing solid samples like rocks, soils, sludge, and biological tissues for elemental detection using instruments like ICP-OES or AAS.
2. Environmental Testing: Digesting water, wastewater, and solid waste to determine parameters like Chemical Oxygen Demand (COD), total phosphorus, and heavy metals.
3. Food and Agriculture: Decomposing food products, plants, and animal feeds to test for toxic heavy metals (lead, cadmium, mercury) and essential nutrients.
4. Industrial and Material Testing: Breaking down tough, indigestible materials like polymers, plastics, ceramics, and battery components (e.g., lithium).
