Anton Paar offers an instrument for microwave-assisted organic synthesis, the Synthos 3000, which is specially designed for the production of chemical compounds in the multigram range. Two powerful magnetrons (1400 W) generate a homogeneous microwave field and allow the rapid heating of sample volumes up to 1 l. Microwave protocols which have been optimized on a small scale can therefore be reproduced easily on a larger scale. The reaction vessels can be used at temperatures up to 300 °C and pressures up to 80 bar. Rotor systems for 8 and 16 vessels enable parallel syntheses and increased sample throughput. Precise temperature and pressure measurement guarantee optimal and safe reaction progress. Synthos 3000 is equipped with numerous safety features which reduce the risks of the consequences of using large amounts of chemicals in the microwave field.
