CEM Microwave™ Synthesis System, Discover® SP with Explorer SP-D Plus 24/48
The CEM Focused Microwave™ Synthesis System, Discover® SP, is designed to enhance the ability to perform chemical reactions under controlled conditions on a laboratory scale. The system facilitates either homogeneous or heterogeneous solution phase chemistry, solid phase chemistry or chemistry conducted on solid supports. It accommodates vessels ranging in working volume from 5mL to 125mL for reactions performed under atmospheric conditions and 10mL or 35mL vessels with septa in addition to 80mL vessels for reactions performed at elevated temperatures and pressures. Primary uses of the Discover are in the discovery and lead optimization phases of the new product development process.
The Discover SP system also incorporates ActiVent Technology which permits the user to release unwanted gaseous byproducts from the reaction to prevent over pressurization and vial failure from gaseous buildup. This ensures safe handling of the vial during and at the end of the reaction. The ActiVent safely bleeds the solvent/vapor from the reaction vessel and releases it through the vent tube connected to the back of the system and into a controlled environment.
Microwave energy is applied to the vessel contents (reactants, catalysts, salts, solvents and/or solid supports) to accelerate the chemical reaction. The microwave absorption properties of some liquid and solid materials, due to their polar and ionic characteristics, have the capability to significantly enhance chemical reactions relative to traditional energy application (heating) techniques. The microwave interaction properties with the reactants, intermediates, catalysts, solid supports and salts provide unique opportunities for the synthetic chemist.
