Synthetic organic chemistry, built on functional group conversions and carbon-carbon bond formation, has long benefited from microwave heating. Microwave reactors have become the industry standard for methodology development and total synthesis because they work better than conventional bench methods, providing: Faster reaction times, Access to different product distributions, more accurate and precise reaction control, faster and more simple reaction setup. Inorganic chemistry from catalyst preparation to solid-state synthesis can take advantage of faster reaction times and improved yields using microwave energy. Compared to conventional heating, microwave energy can also furnish: Unique morphologies and phases, access to novel reaction pathways and lower polydispersity using volumetric heating Useful for both monomer synthesis and subsequent polymerizations, microwave energy provides unique reaction control to influence molecular weight and polydispersity characteristics. Perform reactions in minutes or hours rather than days with the ability to add more monomers, catalysts, or other reagents during the reaction.
The MARS 6 multimode reactor is suitable for running a single vessel or up to 40 in parallel. Fully customizable, the MARS 6 benchtop system can be dedicated for synthesis or serve as an all-in-one microwave reactor for a variety of applications.
The custom-engineered microwave cavity of the MARS 6 is constructed of high-grade 316 solid-steel for maximum safety and coupled with a heavy-duty, spring-mounted door, featuring safety interlocks. Dual magnetrons provide ample power (1800 W) for high-throughput synthesis, and strategically designed waveguides disperse microwave energy uniformly throughout the cavity, providing even heating. CEM’s patented solid-state isolators protect the magnetron from reflected microwave energy, prolonging the lifespan of the system.
Accurate temperature control is critical for controlled heating. The MARS 6 features only the best options for temperature measurement. Inert to microwave energy, the fiber optic temperature probe provides direct in situ temperature measurement of a reference vessel for rapid feedback during both sealed and open vessel reactions. Contactless, volume-independent infrared (IR) sensors accurately measure temperature of all sealed vessels during parallel runs, including those positioned in the inner row of high-throughput vessel sets. When both temperature options are configured on the MARS 6, the DuoTemp technology can dynamically adjust the “Control Vessel” to prevent excessive venting or exothermic reactions. The ability to configure the MARS 6 with appropriate control options, coupled with a full line of vessel technologies, accommodates a variety of chemistries within the realm of synthesis, acid digestion, and extraction. Perform multi-gram to nearly kilogram scale syntheses, teach classes of up to 40 students, use inert atmosphere or add and remove reagents…organic, inorganic, and materials chemistry can all be performed with one microwave system.
