This Heat-On Block is suitable for 250 ml multineck flasks, as the lateral recesses were designed for this purpose.

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 125 ml.
