Microwave Digestion System - Compact 8 Vessel Digester - 1000 W - 250°C, 5 MPa

The Master Science 8-Vessel Microwave Digester is a compact closed-vessel system that heats acids and samples with microwave energy until solid or complex organic and inorganic materials become clear solutions ready for elemental analysis. It suits laboratories with moderate sample numbers that still need full temperature and pressure control.

A mid-infrared sensor reads the true temperature of each sample through the TFM vessel wall, and each vessel has its own pressure limit and relief.
