LLG universal reaction block system for magnetic stirrers. Universal alternative to oil bath The reaction block allows syntheses to be carried out in round flasks at temperatures of up to 250°C. As a result; with this system; oil as a heat transfer media is made redundant and your lab is a safer place. The reaction block ensures safety at work and prevents oil baths and heating mantles from overheating in your lab. The messy oil clean-ups that results from changing oil or removing flasks from an oil bath will be eliminated. Injuries and burns from hot oil will never happen again. Uniform mixing is also guaranteed because there is no interference to the magnetic field from the aluminium blocks. This system ensures optimal heat transfer from the heating plate directly into the medium. Universal model for round plates of 135 to 145mm diameter. With adapter plate for all square plates of min. 145mm length side. Reaction blocks are available in six standard sizes. Delivered adapter allows the use with either IKA or Heidolph magnetic stirrers. Syntheses in round flasks without oil bath up to 250°C. Uniform and constant mixing. High-precision thermal conduction directly into the reaction block. Safe and clean working.
