Why the Milestone RotoSYNTH? PDF Print E-mail
The limitations of the "conventional" laboratory microwave reactors.

The main limitation of most microwave reactors currently available on the market is their inability to properly mix heterogeneous reaction mixtures, particularly in case of ‘thick’ media. This limitation is even more evident when dealing with large quantities of solids. In such cases magnetic or even mechanical stirrers, although improving the bulk homogeneity, are not capable of achieving good results.

Heating solids by conventional systems leads to uneven temperature distribution, due to the poor heating transfer into the bulk of the material. alt
The use of microwave irradiation generally provides a much more homogeneous heating process.  Solids and porous materials are generally thought of as good thermal insulators. Temperatures can be higher in the middle and lower near the container walls. alt
The benefits of the RotoSYNTH
The RotoSYNTH enables a continuous agitation or mixing of material by rotation of the reaction vessel.  This ensures a very homogeneous temperature distribution with microwave irradiation coupled with rotation of the sample.

altHow the RotoSYNTH works

  • Milestone's unique RotoSYNTH system consists of state-of-the-art microwave platform, with a reaction vessel tilted at 45o.  This platform can be used with other standard reaction vessels/rotors simply by removing the rotating vessel.
  • The standard reactor is made of borosilicate glass with volumes of 300 mL and 2 liters.
  • Reaction temperatures is monitored and controlled by dual (contact-less infrared and direct fiber optic) sensors.
  • RotoSYNTH allows processes under inert and atmospheric pressure.
  • The vessel can also be coupled to a vacuum module for the removal or recovery of volatile organics or solvent during microwave irradiation.
