Microwave Synthesizers

Microwave synthesis is a well-accepted technique used by research facilities and major pharmaceutical and biotech companies worldwide. This new technology is changing the way many chemistries are performed, as well as pre-conceived ideas about the capabilities of microwave energy. Microwaves are a low-frequency energy source that is remarkably adaptable to many different types of chemistries including peptide synthesis and proteomic applications.

  • Increase yields in difficult chemistries
  • Increase purity profiles/selectivity
  • Significantly decrease reaction times
  • Access chemistries that can’t be performed with conventional methods



Microwave energy has been used for more than 20 years to accelerate synthetic reactions, which for the most part have been chemistries that could withstand higher temperatures (up to 280 °C). It is a very efficient means of driving reactions to completion, often resulting in higher yields and cleaner chemistries. Microwave energy has the additional advantage of being “instantly on/instantly off”. Because energy is applied directly to the reactants and not transferred through an intermediate system, once the microwave energy source is turned off, the application of energy stops, decreasing the possibility of unwanted side reactions. CEM microwave systems give chemists the ability to tightly control the amount of energy introduced to a reaction, which is especially important when performing temperature- sensitive chemistries such as peptide synthesis and enzymatic digestions.

CEM’s patented microwave peptide synthesizers produce short bursts of finely controlled energy. Such control is not possible with thermal heating methods. This unique utilization of microwave energy significantly increases reaction rates and product purity, overcomes chain aggregation and gives biochemists the unprecedented ability to synthesize peptides that were previously inaccessible by conventional synthetic methods
