Reaction blocks allow syntheses to be carried out in round-bottomed flasks at temperatures up to 180 °C, avoiding the use of oil baths. The system ensures optimum heat transfer from the heating plate directly into the medium. Uniform mixing is also guaranteed since there is no interference to the magnetic field from the aluminium blocks. Reaction blocks range from 100 to 5000 ml in size, and inserts accommodating round bottom flasks from 10 to 3000 ml are available. Due to the wide range of interchangeable inserts, this system can be used for a range of different applications with the RCT, RET and RH magnetic hotplate stirrers.

• Perform safe and clean syntheses in round bottom flasks at temperatures up to 180 °C
• Uniform mixing
• Thermal conduction is directly into the reaction blocks and is very precise
• PTFE coating prevents burning and helps ensure the system is safe to work with
