Product Overview
EXPEC 790S is a microwave-assisted sample pretreatment system developed for demanding laboratory environments where digestion quality, operating safety and turnaround time matter. The system uses directly coupled microwave excitation and patented waveguide coupling technology to improve microwave transfer efficiency and support controlled digestion performance.
Its programmed independent cooling-water circulation, spiral water-cooling concept and pressure-oriented design help shorten cooling time after high-temperature operation. The result is a more workflow-ready system for laboratories that need reliable preparation before downstream elemental analysis or related inorganic testing procedures.
