Heat-on blocks from Radleys offer a means of heating round bottom flasks from 10ml to five litres.
With increasing focus on health and safety issues, many organic synthesis labs are choosing reaction blocks located on stirring hotplates as the preferred way of heating round bottom flasks to eliminate the inherent mess and dangers associated with using oil baths and heating mantles.
However, not all reaction block designs offer the same level of performance, safety and operational productivity.
In comparative tests summarised in Applications Bulletin TDS02S, Radleys showed that the lower thermal mass of heat-on blocks produce faster heat-up times and faster post-synthesis cool-down times than competitive reaction blocks.
In addition, the heat-on well design, which eliminates sticking and cracking of flasks associated with other reaction block designs, maximises the heated surface area further contributing to improved heat-up times.
Heat-on blocks are therefore more efficient as they use less energy to achieve the same results.
