Traditionally, liquid/solid solvent extractions have involved either banks of solvent-hungry Soxhlets or slow, sequential pressurized systems that process 1 sample every 20 minutes. All of that changed with the introduction of microwave extraction, a proven method accepted by government agencies and professional organizations around the world. Microwave extraction decreases extraction times, reduces solvent consumption, improves extraction efficiency, and can help increase the productivity of your laboratory.
Closed-vessel microwave extraction helps reduce solvent usage, aiding in the green chemistry initiatives that many laboratories have adopted. The CEM MARS Microwave Reaction System can perform over 500 microwave extractions using the same amount of solvent normally consumed for only 32 Soxhlet extractions.
Methods that involve nonpolar solvents, which are microwave transparent, can be performed easily with CEM's Carboflon® stir bars without any change to a laboratory’s current solvent scheme.
