This Heat-On Block is suitable for all applications in which a 4 liter round bottom flask is to be heated up. The maximum temperature for continuous use is 260 °C. In order to measure this precisely with a temperature sensor, a small hole is provided on one side of the Heat-On Block. For comfortable and safe transport of the Heat-On Blocks - especially in hot condition - optional safety lifting handles are available separately. For an efficient reaction with no loss of media, it is recommended to use solvent volumes of up to 2 liter.
