This package includes the Multi-Well holder and 3 inserts for small round bottom flasks. The Heat-On inserts are suitable for 25-ml, 50-ml and 100-ml round bottom flasks respectively; a maximum of two flasks at a time can be received by the Multi-Well holder.

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.

The safety lifting handles are optional and so they are available separately.
